Audio problems on the steam deck

That command can either print a url or an error.

Does "iommu=soft" help you?

It does not do anything no output am i supposed to customize the command in any way I put exactly this into the terminal

 sudo journalctl -b | curl -F 'file=@-' 0x0.st

There's somehow a stray newline at the end of your posts?
The the command and then hit enter. sudo will ask you for a password and then curl will show some action and then you get a url - or an error.
Entering that command (you have entered commands into an interactive shell before, right?) and not getting any output is simply not an option.

could I instead upload

   sudo journalctl

as a text file or something I use the terminal regularly I assume I know how to use it right here is a screenshot of my terminal right after pasting the command entering sudo password https://i.imgur.com/qyXEWse.png

The llts kerel does find the audio device but there is no sound, so that does not work. The early 6.18 series kernels worked but after some point no more.

So, I have the same problem as Samuel. I will try iommu=soft but I doubt that it will do anything since earlier I had iommu disabled in the bios and that probably leads to iommu=soft (?)
Probably the only way would be to go back in kernel versions and see where the problem started. Unfortunately I have things running on this computer and I can't keep changing things.

Yes.
But there's something wrong w/ your system

type -a curl
ping -c1 0x0.st

By the way, the current testing kernel shows this in dmesg:

cs35l41 spi-VLV1776:00: probe with driver cs35l41 failed with error -61

cs35l41 is part of the audio DSP system in steam deck.

61 is ENODATA, seems false negative - https://patchew.org/linux/2025120619381 … chyos.org/

I can see the audio device and get very weak audio output on 6.17.9 at least on the headphones jack. I have amplified speakers connected and I can barely hear it.
The only suspicious thing in dmesg is:
acp5x_mach acp5x_mach.0: ASoC: CPU DAI acp5x_i2s_playcap.1 not registered

On 6.18 there was a complaint about acp5x deferred module load. There the audio device did not show up at all.

You've speakers connected to the HP jack? Have you also tried headphones?

amixer -Dhw:0

aa6kj · 2025-12-14 23:16:33

I didn't try headphones. I just used amplified speakers to check if output happens to work to that. The internal speakers did not work (or were too low volume that I would hear them).

Try removing alsa-utils package. It's works for me but volume is a bit low. I have a steam deck LCD. Another possible solution a bit tricky is use ubuntu kernel for 25.10 version. At the momment I am using debian 13 with this kernel with alsa-utils installed and speakers works fine with very high volume. I have tried a lot of kernels (arch-linux, xanmod, liquorix, debian, ubuntu ppa) but the best results that I have obtained is using the official ubuntu kernel 25.10 + alsa-utils installed.

The only thing in there that can have an impact on volume or sound at large are the restore rules.
