CS35L41 amplifiers in an ASUS Zenbook on linux

Asus Zenbook UX3402 speakers on Linux

Important

THIS IS NOW OBSOLETE WITH KERNEL VERSIONS ≥ 6.7.0

A recent announcement in the kernel mail list by Cirrus developers will solve the problem described here. Therefore, the proposed solutions will be soon obsolete. See this comment (thanks, @flukejones, for the tip).

I got the speakers working on my Asus Zenbook 14 OLED UX3402, the one with Intel CPU and the two CS35L41 audio amplifiers connected over SPI (not the UM3402YA, with AMD and I²C). The amplifiers are supported by the snd_hda_scodec_cs35l41 module in recent kernel versions, but they require some model-specific configuration paramaters, that should be provided by the BIOS, via ACPI. Of course, they are missing. It seems that the Windows drivers have those parameters somehow hardcoded, instead of using ACPI (bad idea, but who am I to criticise). Since Asus has been nasty and refused/was not able to update the BIOS with the missing data, I have patched the ACPI tables myself.

Warning

As stated by Cirrus developers, if you try this there is a non-zero (low, I hope) possibility of blowing your speakers. Take into account that this procedure is not just configuring your box, it is hardware-level hacking with very scarce information about the hardware (thank you, ASUS, and thank you, Cirrus, for not publishing the CS35L41 datasheet and making it only available by request). Additionally, You should know how to work with DSDT or SSDT files (I have a brief guide here) and how to recover from a non booting system. You are on your own. You have been warned.

Note

I have used the patch for some months, and everything seems OK. As you can see, the most recent versions do not require electrical parameters to be specified, just providing the functions of several GPIO pins, that are already present in the original BIOS, and the behavior associated to them. I am almost sure that the patch is totally safe.

My BIOS is the most recent one (version 310). I have added two _DSD objects in the SSDT file (ssdt_csc3551.dsl, or its already assembled version, ssdt_csc3551.aml):

  • One inside the SPK1 device, providing the missing "cirrus,dev-index" and other properties, just like the I2C models. You can also provide these properties by patching the kernel module (the linux/sound/pci/hda/cs35l41_hda.c file).

  • Another one, after the SPK1 device, with the chip select GPIOs, "cs-gpios", required by the SPI bus (the somehow simpler I²C bus does not use chip select pins, but addresses). Without this _DSD object, only one amplifier can be addressed and activated. In this case, the driver refuses to load even for this single working amplifier.

Obsolete: DSDT patch

Instead of applying a SSDT file, you may patch the full DSDT dissassembled DSDT file (dsdt.dsl). This was my original solution (thanks to @thor2002ro for pointing to the simpler, nicer SSDT solution, see the comment, especially if you use grub). The patch is available for reference, just apply the SSDT file.

Obsolete: internal boost

I keep the old, original patch, that produced AMP short error messages when the volume was high enough, for reference. Please try first the simpler patch with external boost, that seems to work without flaws (thanks to @bdandy, see the comment).

Boot log

Output from journalctl -b -g CSC3551 --output short-monotonic after the old patch:

The "Falling back to default firmware" disappears if spk-id-gpios are provided (the block is commented in the patch). As a result, a different firmware is loaded, resulting in very low volume and strong distortion. If the new patch is used, that uses external boost, the sound is correct, and the log is

Sorry for replying a bit late, I was busy during the weekend and I faced some other problems with my laptop and I just managed to solve it yesterday.
First, you want to see whether your amps are on i2c or spi. To do this, you run the comman sudo journalctl -b -g CSC3551. If it does not show up anything then maybe you do not have the exactly same amp. My laptop has it on i2c so I see similar things like this:

May 26 15:38:06 mx3340-tbplus kernel: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Error: ACPI _DSD Properties are missing for HID CSC3551.
May 26 15:38:06 mx3340-tbplus kernel: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: error -EINVAL: Platform not supported
May 26 15:38:06 mx3340-tbplus kernel: cs35l41-hda: probe of i2c-CSC3551:00-cs35l41-hda.0 failed with error -22

Then you'll have to dump your dsdt table following OP's guide (here). One you have it decompiled and got the dsdt.dsl, you open it and search for CSC3551. All of the things you have to patch will be inside that scope (...) block. First you copy the first _DSD block from the patch and add it directly after the empty _DIS method, so it will look something like this:

...

                       SPKR, 0x02, Zero, Zero,
                    } },
                    Package () { "cirrus,speaker-position",     Package () { Zero, One } },
                    // gpioX-func: 0 not used, 1 VPSK_SWITCH, 2: INTERRUPT, 3: SYNC
                    Package () { "cirrus,gpio1-func",           Package () { One, One } },
                    Package () { "cirrus,gpio2-func",           Package () { 0x02, 0x02 } },
                    // boost-type: 0 internal, 1 external
                    Package () { "cirrus,boost-type",           Package () { One, One } },
                },
            })
...

The whole scope block of my laptop could be found in my previous post.
Notice that I have SPKR instead of SPK1 and Package () { "cirrus,dev-index", Package () { 0x0040, 0x0041 }} instead of {Zero, One}? These are the device specific thing you have to change here. The device name could be found in the brackets of the header of the device block, in my case it is: Device (SPKR) {... so I replace SPK1 with SPKR. Since your device is also ASUS maybe it is the same SPK1 so you don't have to change it.
The second change there was the ID of the two buses. You kind find these information under the Name (BRUF, ... which is inside the Name (_UID, .... That for my device looks like:

...
            Name (_UID, One)  // _UID: Unique ID
            Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
            {
                Name (RBUF, ResourceTemplate ()
                {
                    I2cSerialBusV2 (0x0040, ControllerInitiated, 0x000F4240,
                        AddressingMode7Bit, "\\_SB.PC00.I2C7",
                        0x00, ResourceConsumer, , Exclusive,
                        )
                    I2cSerialBusV2 (0x0041, ControllerInitiated, 0x000F4240,
                        AddressingMode7Bit, "\\_SB.PC00.I2C7",
                        0x00, ResourceConsumer, , Exclusive,
                        )
...

So I replace the {Zero, One} with {0x0040, 0x0041}.
According to OP, if your amps are on SPI then you also want to add the second _DSD block in the patch outside of the device (...) block but still inside the scope.
Once you done that, go back to nearly the beginning of the file, change the very last parameter in the DefinitionBlock (... to a larger value to prioritize this patched table over that from the BIOS. It was 0x00 on my device, but it is probably a larger value on your device and you just have to change it to a larger number. Mine is:

DefinitionBlock ("", "DSDT", 2, "LENOVO", "CB-01   ", 0x00000009)

After that you follow the guide to recompile and package it into a .cpio file. Copy the .cpio file into /boot. If you use grub, on reboot you press "e" toward the boot option to enter the edit screen, load this cpio as an init ramdisk after the microcode and before the kernel's initrd. For example it might look like this:

...
initrd  /boot/intel-ucode.img /patched_dsdt.cpio /boot/initramfs-6.3.4.img

Run sudo journalctl -b -g CSC3551 again, if there is no error but similar output as that in my previous post, then the ACPI table patch worked. If your speakers work at this moment, then you are done (you may want to write the initrd loading command into grub's config so you won't need to type that manually on every reboot).
If they are still not working, you need to patch the driver in the kernel. Look for a guide to build a mainline kernel (btw. you need Linux 6.1+ for these speakers to work). I am using Manjaro Linux and I followed the guide on ArchWiki. Once you have the full kernel source ready, go to kernel_source_root/sound/pci/hda/patch_realtek.c and search for FIXUP_CS35L41_ until you find a list of things like this:

SND_PCI_QUIRK(0x1043, 0x12af, "ASUS UX582ZS", ALC245_FIXUP_CS35L41_SPI_2),
...

Add a new line in the same format for your laptop.
The first two parameters can be find from the Subsystem ID. Run alsa-info to obtain it. In the output file, search for Subsystem Id and you get a 4 bytes long hex string, for example mine looks like: Subsystem Id: 0x17aa3875. Put the first four characters into the first parameter and the second for characters into the second parameter. The third parameter is just how you call your laptop, it does not matter in terms of functions and can be whatever. The last parameter could be ALC245_FIXUP_CS35L41_SPI_2 or ALC287_FIXUP_CS35L41_I2C_2 depends on whether your amps are on spi or i2c.
For my device specifically, the line is like:

SND_PCI_QUIRK(0x17aa, 0x3875, "Thinkbook Plus Gen3", ALC287_FIXUP_CS35L41_I2C_2)

Then you just build the kernel and set it up for the bootloader. Don't forget to include the .cpio with your patched dsdt table as a initrd. If you are lucky enough at this point your speakers should be finally working.

Hi! I think your laptop has the exactly same problem which is the dsdt table missing _DSD properties (and I don't really think ASUS did already fixed it in your case). From the information I see, you can probably just apply the patch by OP without any changes. So the patched table for your laptop would probably be like this:

Scope (_SB.PC00.SPI3)
{
    Device (SPK1)
    {

Alternatively, since the exactly same patch will likely work for your laptop, you cam probably use the sddt patch directly provided by OP following the the "Option 2" of this guide which would be easier.
After applying the patch if the errors are gong but speakers still not working, you'll need to patch the kernel following the steps in my previous post.
BTW. you should really thank @lamperez for the patch and other people who figured out how the kernel driver should be patched! All what I did is just sharing the process how I used their works to get the speakers of my laptop working.

If your speakers are still not working, then that means the ACPI patch is done correctly but the kernel has to patched for them to work.

Sorry to bother but i don't understand what i need to do more to the kernel, i saw your very useful comment here where you get the same error,
but i have no idea, what to do with linux/sound/pci/hda/patch_realtek.c, i have an UX3402ZA so i'm not sure i need to do something else ?

Thanks.

Sorry for replying a bit late, I was busy during the weekend and I faced some other problems with my laptop and I just managed to solve it yesterday. First, you want to see whether your amps are on i2c or spi. To do this, you run the comman sudo journalctl -b -g CSC3551. If it does not show up anything then maybe you do not have the exactly same amp. My laptop has it on i2c so I see similar things like this:

May 26 15:38:06 mx3340-tbplus kernel: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Error: ACPI _DSD Properties are missing for HID CSC3551.
May 26 15:38:06 mx3340-tbplus kernel: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: error -EINVAL: Platform not supported
May 26 15:38:06 mx3340-tbplus kernel: cs35l41-hda: probe of i2c-CSC3551:00-cs35l41-hda.0 failed with error -22

Then you'll have to dump your dsdt table following OP's guide (here). One you have it decompiled and got the dsdt.dsl, you open it and search for CSC3551. All of the things you have to patch will be inside that scope (...) block. First you copy the first _DSD block from the patch and add it directly after the empty _DIS method, so it will look something like this:

...
            Method (_DIS, 0, NotSerialized)  // _DIS: Disable Device
            {
            }

            Name (_DSD, Package ()   // _DSD: Device-Specific Data
            {
                ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
                Package ()
                {
                    Package () { "cirrus,dev-index", Package () { 0x0040, 0x0041 }},
                    Package () { "reset-gpios", Package () {
                       SPKR, One, Zero, Zero,
                       SPKR, One, Zero, Zero,
                    } },
                    Package () { "spk-id-gpios", Package () {
                       SPKR, 0x02, Zero, Zero,
                       SPKR, 0x02, Zero, Zero,
                    } },
                    Package () { "cirrus,speaker-position",     Package () { Zero, One } },
                    // gpioX-func: 0 not used, 1 VPSK_SWITCH, 2: INTERRUPT, 3: SYNC
                    Package () { "cirrus,gpio1-func",           Package () { One, One } },
                    Package () { "cirrus,gpio2-func",           Package () { 0x02, 0x02 } },
                    // boost-type: 0 internal, 1 external
                    Package () { "cirrus,boost-type",           Package () { One, One } },
                },
            })
...

The whole scope block of my laptop could be found in my previous post. Notice that I have SPKR instead of SPK1 and Package () { "cirrus,dev-index", Package () { 0x0040, 0x0041 }} instead of {Zero, One}? These are the device specific thing you have to change here. The device name could be found in the brackets of the header of the device block, in my case it is: Device (SPKR) {... so I replace SPK1 with SPKR. Since your device is also ASUS maybe it is the same SPK1 so you don't have to change it. The second change there was the ID of the two buses. You kind find these information under the Name (BRUF, ... which is inside the Name (_UID, .... That for my device looks like:

...
            Name (_UID, One)  // _UID: Unique ID
            Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
            {
                Name (RBUF, ResourceTemplate ()
                {
                    I2cSerialBusV2 (0x0040, ControllerInitiated, 0x000F4240,
                        AddressingMode7Bit, "\\_SB.PC00.I2C7",
                        0x00, ResourceConsumer, , Exclusive,
                        )
                    I2cSerialBusV2 (0x0041, ControllerInitiated, 0x000F4240,
                        AddressingMode7Bit, "\\_SB.PC00.I2C7",
                        0x00, ResourceConsumer, , Exclusive,
                        )
...

So I replace the {Zero, One} with {0x0040, 0x0041}. According to OP, if your amps are on SPI then you also want to add the second _DSD block in the patch outside of the device (...) block but still inside the scope. Once you done that, go back to nearly the beginning of the file, change the very last parameter in the DefinitionBlock (... to a larger value to prioritize this patched table over that from the BIOS. It was 0x00 on my device, but it is probably a larger value on your device and you just have to change it to a larger number. Mine is:

DefinitionBlock ("", "DSDT", 2, "LENOVO", "CB-01   ", 0x00000009)

After that you follow the guide to recompile and package it into a .cpio file. Copy the .cpio file into /boot. If you use grub, on reboot you press "e" toward the boot option to enter the edit screen, load this cpio as an init ramdisk after the microcode and before the kernel's initrd. For example it might look like this:

...
initrd  /boot/intel-ucode.img /patched_dsdt.cpio /boot/initramfs-6.3.4.img

Run sudo journalctl -b -g CSC3551 again, if there is no error but similar output as that in my previous post, then the ACPI table patch worked. If your speakers work at this moment, then you are done (you may want to write the initrd loading command into grub's config so you won't need to type that manually on every reboot). If they are still not working, you need to patch the driver in the kernel. Look for a guide to build a mainline kernel (btw. you need Linux 6.1+ for these speakers to work). I am using Manjaro Linux and I followed the guide on ArchWiki. Once you have the full kernel source ready, go to kernel_source_root/sound/pci/hda/patch_realtek.c and search for FIXUP_CS35L41_ until you find a list of things like this:

SND_PCI_QUIRK(0x1043, 0x12af, "ASUS UX582ZS", ALC245_FIXUP_CS35L41_SPI_2),
...

Add a new line in the same format for your laptop. The first two parameters can be find from the Subsystem ID. Run alsa-info to obtain it. In the output file, search for Subsystem Id and you get a 4 bytes long hex string, for example mine looks like: Subsystem Id: 0x17aa3875. Put the first four characters into the first parameter and the second for characters into the second parameter. The third parameter is just how you call your laptop, it does not matter in terms of functions and can be whatever. The last parameter could be ALC245_FIXUP_CS35L41_SPI_2 or ALC287_FIXUP_CS35L41_I2C_2 depends on whether your amps are on spi or i2c. For my device specifically, the line is like:

SND_PCI_QUIRK(0x17aa, 0x3875, "Thinkbook Plus Gen3", ALC287_FIXUP_CS35L41_I2C_2)

Then you just build the kernel and set it up for the bootloader. Don't forget to include the .cpio with your patched dsdt table as a initrd. If you are lucky enough at this point your speakers should be finally working.

thanks!

Hello everyone! First of all thank you to @Moooebie @lamperez for their awesome work! I got the same problem as @Moooebie but with a thinkbook 13x gen2, I was just following your steps, so what I did is:

  1. sudo journalctl -b -g CSC3551
Jun 05 14:45:05 wizard kernel: Serial bus multi instantiate pseudo device driver CSC3551:00: Instantiated 2 I2C devices.

By reading this for sure my speaker is in I2C.

  1. Decompile and get the dsdt.dsl, then search for CSC3551

I did it but there's no match for CSC3551, nor SPKR or SPK1, although I have SPKP, so I don't want to do something that I'm not that certain, so just wanted to ask you guys what could be the best move from here? Thank you so much for reading!

It seems strange, since the devices are called i2c-CSC3551:00-cs35l41-hda.0 (and 1). To my understanding, the kernel only tries to load the cs35l41-hda module if the ACPI device is called CLSA0100, CLSA0101 or CSC3551, as you can see in the source file (for SPI connected devices, only the last one).

Thank you for the patch and @lamperez for the explanation as to what steps to take to attempt to get this to work. I have a ASUS ROG Strix G733PZ which is also missing the DSD properties. I followed the guide, created the CPIO file and booted into Arch Linux. The kernel can now see the device. I also installed sol-firmware but I still get no sound. So it will need the laptop adding to the driver's sound PCI quirk section (at this time by compiling the kernel which I haven't got round to yet due to work commitments).

To save anyone in the future the work I did, the laptop's ID for the two buses is the same as in the guide, the speakers are referred to as SPKR and the amps are on i2c so the sound PCI quirk line should be:

SND_PCI_QUIRK(0x1043, 0x1503, "ASUS ROG Strix G733PZ", ALC287_FIXUP_CS35L41_I2C_2),

I'm not familiar with submitting patches to the kernel but hopefully this helps in the investigation to get other people's speakers working.

Anyone else here have i2c and have it where you won't have sound during reboots and if you do a full power restart (hold power button) then the sound will work again? Another way to get it working is to do three reboots. I suspected it was the GPIO reset but I'm not so sure.

I have the same issue (also i2c), but not necessarily a force power off by holding the power button, but simply using the "shutdown" option in the OS is enough. If the computer is rebooted then the sound will not work, there are some errors in journalctl log but I don't really have an idea about that...

Thats great! I noticed that putting the system to sleep and waking it up breaks audio for me. Can you confirm that is the case for you too? If i can resolve this then it'll be perfect on the Asus Ally.

The need of changing reset-gpios for i2c devices is logical. GPIO indexes are a sequence starting from zero.

For SPI devices:

  • index 0: chip select of one of the amplifiers (cs-gpios),
  • index 1: reset of both amplifiers (reset-gpios),
  • index 2: speaker id (spk-id-gpios).

For i2c devices, the chip select is missing, and therefore you must shift the others by one:

  • index 0: reset (reset-gpios)
  • index 1: speaker id (spk-id-gpios).
