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

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...

What errors are you getting in your log?

Like this:

                    SPKR, One, Zero, Zero
                } },

to fix it do this

                Package () { "reset-gpios", Package () {
                    SPKR, Zero, Zero, Zero,

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

Also here's my journalctl:

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.

@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.

@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.

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

Asus just doesn't care at all....
Might need some adjustment on bios update... But doubt asus will release another bios.... They usually release 2-3 bios-es at launch the forget about it

Yea its a real shame, in the end i opted for windows and WSL for this device (becauseit's a work pc). With the XPS 15 i had the best experience on linux it worked event better than on windows.

Compile a newer version of linux kernel (> 6.1). I'm using linux mint 21.2 with kernel 6.3.9.
5.19 is way too old and doesn't include cs35l41 firmware. After booting up linux with the new kernel, follow this https://github.com/thor2002ro/asus_zenbook_ux3402za.
My ux3402za's speaker is working properly for me.
Note that the compilation process may take 1-2 hours

Nothing actually, but I do recommend backing up your important files first. I got some issue with initramfs after booting up with the new kernel so I used the old kernel and ran the following command
sudo make modules_install INSTALL_MOD_STRIP=1

I got an initramfs issue too while it waited for my encrypted drive. Couldn't get passed that point. Had to revert to old kernel. sudo make modules_install produces a make error. No matter, I'll keep on with it and post back my findings.

sudo dmesg | grep SSDT output is seems to be correct I have the line with patch:

I also tried to extract dsdt.dat by your guide: https://gist.github.com/lamperez/d5b385bc0c0c04928211e297a69f32d7 and dsdt.dsl has nothing CSC3551 related in that file

Device: asus_zenbook_s13_ux5304va
My kernel is: 6.2.6-76060206-generic
Dual Boot: No
Secure Boot: Disabled
Fastboot: Disabled
BIOS Version: 304

I'm assuming I need to modify the patch itself somehow?

P.S: Begging for help 😸

It won't work on a different models kernel it needs to be adapted and also you have to look it the kernel is patched for you model the quirk is applied based on sound card id

got it, I'll try to build kernel from sources then with my model included as @Moooebie wrote in his guide, s13 and 14 zenbooks are pretty much the same I had a hope that it will work without kernel patches, I created a working dsl patch (by modifiing depackaged dsdt.dat) via: https://gist.github.com/lamperez/d5b385bc0c0c04928211e297a69f32d7

at least the sudo journalctl -b -g CSC3551 outputs no errors but still no sound, going after kernel then, if that will be successful I'll upload a source code for my model to git, but the question that comes in mind, that to make users life easier just by appling patch without kernel modification as you mentioned my device SND_PCI_QUIRK(0x1043, 0x16d3, "ASUS UX5304VA", ALC245_FIXUP_CS35L41_SPI_2), should be included in kernel, I've never done the kernel modification before, if I'm modifying ubuntus kernel I have to find the kernel sources on ubuntu git and submit a pr?

I have a good news and bad news, good one is that patching kernel done the job, I've got the sound thatnks a lot for guides @lamperez @Moooebie @thor2002ro but with custom kernel wifi module is missing now 😸

wifi is working, just installation of kernel went wrong.
2 new issues I'm trying to solve will keep everyone here updated:

  1. When laptop goes to sleep, speakers doesn't work after wake up
  2. Since speakers are harman kardon branded sound on linux is complete crap comparing to windows, trying to bring some quality back with Easy Effects package but so far no luck.
