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).

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

I have a Dell XPS 15 9530 that seems to have the same CS35L41 amplifier and resulting ACPI _DSD Properties are missing for HID CSC3551 dmesg error. I've tried everything suggested here and this wiki, but it looks like the kernel module is attempting to load more firmware files than the Dell drivers provide. I figured out that if I omit spk-id-gpios from the ssdt patch, it attempts to load the correct firmware files, but it takes several minutes and the sounds doesn't seem improved.

Can someone tell me what some of these properties in the ssdt patch do, or how I can determine the correct values for my hardware?

I uninstalled the patch since it was for another model, and tried to follow this guide to patch it myself.

dsdt.dsl values are:

    Scope (_SB.PC00.SPI0)

            },

    }
}

and I'm still having sound issues and this is what I have in dmesg:

I think the OTP_BOOT_DONE error is from not having the cs-gpios for SPI devices

Hi Guys, I'm just with a new machine (ASUS ROG Flow Z13 model GZ301VU) trying to make sound working. Obviously, as in the other cases it works with 3.5jack but speakers are silent.
I'm on Ubuntu 23.04, GRUB.
Once installed kernel 6.4.6 and modified: /etc/modprobe.d/alsa-base.conf as described here: look for "Kernel Patch" section + disabling post BIOS sound (during ROG logo), I made it to enables speakers, but they work only with tweeters. Sound is very shallow, so I believe amps are not working. There are still errors in the dmesg, it acknowledges, it does not work as expected:

I understand then, my Cirrus amps are driven by SPI1?

Is there any ready patch for this config?

Thanks for any help,

Warning: patch doesnt work without kernel modification (described in repo readme)

i had similar success on a 2023 Asus Zenbook Pro 14 UX6404VV. it required kernel patching as well as a patched dsl, but the sound is so terrible the effort doesnt even feel worth it.
when it comes to step 2 in this patch repo for the ux3504va the entry is as follows:
SND_PCI_QUIRK(0x1043, 0x1863, "ASUS UX6404VV", ALC245_FIXUP_CS35L41_SPI_2)

i've had very mixed results with this particular model and things working, but Ubuntu 23.04 seems to be the best starting point and manually compiling the iwlwifi driver instead of using apt

i'll clone this repo and modify it for the UX6404VV in the next day or so.

                Return (SBUF) /* \_SB_.PC00.SPI1.SPK1._CRS.SBUF */
            }

            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (0x0F)
            }

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

I understand then, my Cirrus amps are driven by SPI1?

Is there any ready patch for this config?

Thanks for any help,

P.

you'll need to include the _DSD section. example and also patch the kernel.

in my last test case the dsl example i used was this: https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff?permalink_comment_id=4600010#file-ssdt_csc3551-dsl

this guide helps understand whats happening: https://asus-linux.org/wiki/cirrus-amps/

@wrighterase
Thanks for your support.
I made following steps:

1. Created DSD patch as follows:

DefinitionBlock ("", "SSDT", 1, "CUSTOM", "CSC3551", 0x00000002)
{
    External (_SB_.PC00.SPI1, DeviceObj)
    External (_SB_.PC00.SPI1.SPK1, DeviceObj)

    Scope (_SB.PC00.SPI1.SPK1)
    {
        Name (_DSD, Package ()   // _DSD: Device-Specific Data
        {
            ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
            Package ()
            {
                Package () { "cirrus,dev-index", Package () { Zero, One }},
                Package () { "reset-gpios", Package () {
					SPK1, One, Zero, Zero,
					SPK1, One, Zero, Zero,
                } },
                Package () { "spk-id-gpios", Package () {
					SPK1, 0x02, Zero, Zero,
					SPK1, 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 } },
            },
        })
    }
    Scope (_SB.PC00.SPI1)
    {
        Name (_DSD, Package ()
        {
            ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
            Package ()
            {
                Package () { "cs-gpios", Package () { 
                    Zero,                    // Native CS
                    SPK1, Zero, Zero, Zero   // GPIO CS
                } }
            }
        })
    }
}

2. Assembled, injected cpio via GRUB,
3. Copied firmware as instructed in https://gitlab.com/asus-linux/firmware
4. Rebooted

Now all dmesg errors are gone but there are no DSP sections as other users reported:

There is also no report on loading firmware.

Now there is no sound at all :(

Did I miss any steps?

The new SSDT patch has made sound better for my asus m16 G604, but its still not up to the mark as system is using default cirrus firmware. Am using latest provided SSDT patch and appropriate cirrus firmware for my laptop as per asus-linux blog on this

Now there is no sound at all :(

Did I miss any steps?

thats partial success. when i got the same logs as you now have, i needed to then patch the kernel. you can use @badger-lviv-ua repo here to get that part done as it mostly outlines whats required.

you'll need to pull the kernel source with apt-get source (this link may help you: https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel) and then patch sound/pci/hda/patch_realtek.c with something like this: SND_PCI_QUIRK(0x1043, 0x1863, "ASUS UX6404VV", ALC245_FIXUP_CS35L41_SPI_2) where 0x1043 is the SubVendor id and 0x1863 is the SubDevice id. these can be found using lspci and then using the PCI device name with hwinfo to find them. in my case as an example...
lspci shows Multimedia audio controller
hwinfo | grep "Multimedia audio controller" -A 10

hope this helps.

For anyone having issues with the ASUS ROG STRIX G17 (2023) G713PV:

I've used the following dsl patch:

DefinitionBlock ("", "SSDT", 1, "CUSTOM", "CSC3551", 0x00000001)
{
    External (_SB_.I2CD, DeviceObj)
    External (_SB_.I2CD.SPKR, DeviceObj)

    Scope (_SB.I2CD.SPKR)
    {
        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, Zero, Zero, Zero,
                   SPKR, Zero, 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 following works with grub:
Compile it with: iasl -tc speaker_amplifier_fix_patch.dsl, copy the resulting speaker_amplifier_fix_patch.aml file file to the boot partition (mostly /boot). Then add the entry acpi speaker_amplifier_fix_patch.aml to the grub config, e.g. to the /etc/grub.d/40_custom file. Don't forget to regenerate your grub config (sudo grub-mkconfig -o /boot/grub/grub.cfg on Arch).

You also need the newest linux-firmware version (20230804) (on arch as of writing only available via AUR linux-firmware-git).
Also the newest kernel version (6.4.8) is necessary.

It is possible to get it working with older kernel by adding some modprobe options to snd-hda-intel, but I don't know which exactly.
Instead of using the newest linux-firmware you can also create links to all files in /lib/firmware/cirrus containing -10431503- by replacing it with -10431d1f-, e.g. cs35l41-dsp1-spk-prot-10431d1f-spkid0-l0.bin -> cs35l41-dsp1-spk-prot-10431503-spkid0-l0.bin

Thanks to this gist and the information in https://asus-linux.org/wiki/cirrus-amps/#create-the-ssdt-patch

Hi. 🙂

A friend of mine recently bought an Asus Zenbook 15 UM3504DA laptop (2023) and installed Fedora Workstation 38 (currently Linux kernel 6.4.8). Unfortunately, the system is unable to produce sound via the built-in speakers. However, speakers connected via jack or Bluetooth provide a functional audio output.

We followed the tutorial at https://asus-linux.org/wiki/cirrus-amps/. (Many thanks to its creators!)
We installed the following SSDT patch:

DefinitionBlock ("", "SSDT", 1, "CUSTOM", "CSC3551", 0x00000001)
{
    External (_SB_.I2CB, DeviceObj)
    External (_SB_.I2CB.SPKR, DeviceObj)

    Scope (_SB.I2CB.SPKR)
    {
        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, Zero, Zero, Zero,
					SPKR, Zero, 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 } },
            },
        })
    }
}

And we installed the 104318d3 firmwares from https://gitlab.com/asus-linux/firmware/-/tree/main/cirrus:

$ ls /lib/firmware/cirrus/ | grep 104318d3
cs35l41-dsp1-spk-cali-104318d3-spkid1-l0.bin
cs35l41-dsp1-spk-cali-104318d3-spkid1-r0.bin
cs35l41-dsp1-spk-prot-104318d3-spkid1-l0.bin
cs35l41-dsp1-spk-prot-104318d3-spkid1-r0.bin

This gave the system speaker recognition, as I understand it:

However, the sound is still not working on his computer and it seems to me that some lines are missing in the command return above. Is it necessary to patch and compile the Linux kernel to enable sound to work, even on the latest versions of the Fedora kernel (6.4.8)? Or do we need to do other things to do this?

Thank you for taking the time to read my message. 🪷

Hey guys, I have a G634JZ (Rog Strix Scar 16 2023), using following ssdt(dsdt shows SPI3 and SPK1):

The kernel patch of this device (1043:1caf) seems in the linux-g14 kernel patch code, which I'm using.

So anyone happened to fix the OTP_BOOT_DONE?

Apologies for the delay in communication, I was away.
So I need to compile kernel, anyway?
I'm trying to follow the links you've shared (thanks @wrighterase) but I'm stuck with obtaining building dependencies for a kernel. To be clear, I've updated Ubuntu 22.04 kernel to the version 6.46 (using Mainline Kernels App):
$ sudo apt-get build-dep linux linux-image-$(uname -r) Reading package lists... Done E: Unable to find a source package for linux-image-6.4.6-060406-generic
--EDIT--
Meanwhile, I found sub-ids:

57: PCI 05.0: 0480 Multimedia controller
  [Created at pci.386]
  Unique ID: CvwD.Dtjiosnz0WC
  SysFS ID: /devices/pci0000:00/0000:00:05.0
  SysFS BusID: 0000:00:05.0
  Hardware Class: unknown
  Model: "Intel Multimedia controller"
  Vendor: pci 0x8086 "Intel Corporation"
  Device: pci 0xa75d 
  SubVendor: pci 0x1043 "ASUSTeK Computer Inc."
  SubDevice: pci 0x1573 
  Memory Range: 0x682e000000-0x682effffff (rw,non-prefetchable,disabled)

  Config Status: cfg=new, avail=yes, need=no, active=unknown

So, the correct patch in the sound/pci/hda/patch_realtek.c would be then:
SND_PCI_QUIRK(0x1043, 0x1573, "ASUS GZ301VU.306", ALC245_FIXUP_CS35L41_SPI_2),?
Just wonder, my soundcard seems to be on SPI1, not SPI2 (as in the patch, but there is no SPI1)...

Any help appreciated.

For everyone ending up here through a boogle search, please see my guide (built from everything here) https://asus-linux.org/wiki/cirrus-amps/ for more info.

I have been pushing Cirrus devs to create proper solutions, and so far we have a patch merged by Taki, and I've submitted a new patch to finish enabling ASUS amps. The info is at the top of the article to be clear.

Subject: [PATCH] ALSA: hda: cs35l41: Support ASUS 2023 laptops with missing
 DSD

Support adding the missing DSD properties required  for ASUS ROG 2023
laptops and other ASUS laptops to properly utilise the cs35l41.

The currently added laptops are:
- ASUS GS650P,   i2c
- ASUS GA402X,   i2c
- ASUS GU604V,   spi
- ASUS GU603V,   spi
- ASUS GV601V,   spi
- ASUS GZ301V,   spi
- ASUS ROG ALLY, i2c
- ASUS G614J,    spi
- ASUS G634J,    spi
- ASUS G614JI,   spi
- ASUS G713P,    i2c
- ASUS H7604JV,  spi

The SPI connected amps may be required to use an external DSD patch
to fix or add the "cs-gpios" property.

@flukejones Thanks for your effort, really appreciate that.

I have GZ301V so let me know how / if I can be in help for testing.

@pczekalski follow the guide I posted.

@flukejones Thanks, I've carefully checked your manual, just one doubt: on the list of 6.5 rc7 my laptop Asus ROG Flow Z13 (GZ301V) is listed in the SPI_2 section. While my SSDT ssdt16.dsl shows it is SPI1:

Current patch, relies on the patch mentioned in my other post still. I2C laptops need to remove the DSD patch hack, and SPI laptops need only the cs-gpio DSD entry.

Hi.
I have bought 'ASUSTeK COMPUTER INC. Zenbook S 13 UX5304VA_UX5304VA' and got similar issue on fedora ws 38:
[ 6.806137] fedora kernel: Serial bus multi instantiate pseudo device driver CSC3551:00: Instantiated 2 SPI devices.

and I have to mention I'm really new in linux. how I can resolve this problem and where i have to start from?

@AlirezaDadrass what kernel version are you running? (Paste the output of uname -a)

You could try with this:

@flukejones I don't see the UX3402 (Asus Zenbook) in the list. What I understand is that you're trying to get a patch upstreamed so that no manual patching is required, right? I am using the ssdt patch right now but it'd be nice for other people to have it bundled with the drivers. I'm happy to test things out in my UX3402 if that's of any help!

The currently added laptops are:

• ASUS GS650P, i2c
• ASUS GA402X, i2c
• ASUS GU604V, spi
• ASUS GU603V, spi
• ASUS GV601V, spi
• ASUS GZ301V, spi
• ASUS ROG ALLY, i2c
• ASUS G614J, spi
• ASUS G634J, spi
• ASUS G614JI, spi
• ASUS G713P, i2c
• ASUS H7604JV, spi

Hi @AlirezaDadrass, have you tried this patch? https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff?permalink_comment_id=4639491#gistcomment-4639491

Thanks everyone in this thread! After a lot of iterations I managed to supply my Asus Zenbook 15 UM3504DA with working speakers!

For anyone facing the same issue with the Zenbook 15, give me a message; the working steps included

• Following the guide on the asus-linux website: here
• This very helpful comment, thanks! https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff?permalink_comment_id=4582983#gistcomment-4582983
• building my own linux kernel with the patch from that comment
• changing the dsl config a number of times until I ended up on the following:

    }


}

I am very greatful for all the guides and especially the asus-linux website.

Some problems I encountered along the way:

• The asus-linux website does not provide any information the needed kernel patch; I found that in the comments here
• The 6.5 kernel does have the patch for some models, but not mine
• There are many versions of the .dsl file floating around, I still don't know what is correct

Hi @AlirezaDadrass, have you tried this patch? https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff?permalink_comment_id=4639491#gistcomment-4639491

Hi
No I didn't.
there is a command 'sudo update-grub'
sudo: update-grub: command not found

@AlirezaDadrass might be that you have systemd-boot and not GRUB, check /efi/loader

Hello again.
I tried this solution and build the kernel and installed it. nothing happen

@AlirezaDadrass might be that you have systemd-boot and not GRUB, check /efi/loader

no i have grub2 and /boot folder

I got
