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

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).

Not working for me with ux3402va

Used SND_PCI_QUIRK(0x1043, 0x16a3, "ASUS UX3402", ALC245_FIXUP_CS35L41_SPI_2). I have a chinese version, so maybe I need to use another id? How could I find out which one I need to use?

Installed sof-firmware package and now everything works!

The Tables modifications and Updating to Kernel: 6.3.7-arch1-1 today made everything working thanks again for this great work @lamperez

Maybe someone familiar with contributing to kernel could submit this patch to make ux3402va also work?
https://gist.github.com/PoSayDone/ec01ba84e5aad40f229b034f6beec5d9

It looks like the Asus Ally has the same missing fields....How exactly did you know what values to use?

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...

I believe I just fixed the restart problem as well. I had some stuff at /etc/modprobe.d/alsa-base.conf I commented it out and rebooted and it's working now with reboot and shutdown.

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).

The audio breaking after suspend is related to the kernel module, that is the one that should restore the original state. The ACPI just provides the information to the kernel. Maybe a missing quirk for the specific model? I dunno.

Is there a general instruction how to fix the sound on Zephyrus G16 GU603VV?

I just purchased the laptop and I would like to be very careful with patching anything. Which patch should I apply? Should I modify anything? Thanks in advance

I used this patch: https://github.com/thor2002ro/asus_zenbook_ux3402za/tree/main/Sound it worked!

Finally got my ux3402za speakers working on linux using the ssdt solution! You guys rock!!! It spits out some acpi error on boot but speakers are working normally so I guess it's fine in the long run, I hope

Thank you very much to everyone involved, especially to @lamperez and @thor2002ro for providing the DSDT patch and the guide to apply it!!!! It worked perfectly on the UX3402ZA.

@SergioASantosF What guide did you follow, I tried https://github.com/thor2002ro/asus_zenbook_ux3402za/blob/main/Sound/README.md but it doesn't work. I'm also using UX3402ZA. and I followed all the guide

Is that normal?

@cw-87-tw I'm having the same issue. Please post back if you find a solutions.

@cw-87-tw, I followed exactly the tutorial that you also tried, using the files provided by @thor2002ro , without making any modifications, and it worked here on Debian 12, Ubuntu, and Fedora 38 (which is currently installed).

I don't know if it's because I don't have dual boot, so I didn't encounter any issues with the grub update.

Since it was my first attempt and it didn't give any errors, I won't be able to help you.

@cw-87-tw @speedy01 that output looks completely normal (it's detecting the ACPI table and it's detecting a windows installation). What issue are you having?

@fermino the issue I'm having is "still no sound" from what I can tell, grub is not loading the custom tables. even though the entry is in the grub.cfg

@speedy01 maybe the grub cfg is being used from another location? Try pressing e in the GRUB screen and see if the ssdt line is there (press ctrl+x in that screen to boot).

@fermino thanks for the hint. when I manually entered the command, I got an error. Turns out the secure boot is preventing grub from running acpi. A workaround for me was to disable secure boot.

this also pops up...but prob nothing.

@speedy01 awesome! Did it work?

@fermino yes..disabling secure boot allowed grub to load custom table. I have sound! :)

Just got a new laptop, the asus ux5304v and to no surprise (after reading this thread) the audio doesn't work (just the speakers don't). Did anyone here try to apply the patch to this specific device ?

Another question i have is will this get overwritten if there is a BIOS update?
Does asus even push firmware updates for linux devices (like DELL does) or do i need to dualboot windows for the firmware updates (or if i don't want to dual boot, apply them manually myself)?

P.S. I am quite a linux newbie especially when it comes to this level of customization (BIOS level) and am not really keen into giving so much time to just have a working machine

Thank in advance
