I'm using the latest gentoo-sources on the steam deck and everything works fine except for the audio.

I have enabled support for it:
Quote:

CONFIG_SND_SOC_AMD_ACP5x=m
CONFIG_SND_SOC_AMD_VANGOGH_MACH=m


But there is no audio and dmesg yields this:
Quote:

platform acp5x_mach.0: deferred probe pending


Output of lspci
Output of dmesg

Any help would be appreciated!

I have already enabled SND_HDA_INTEL the issue is not with audio trough HDMI, the issue is with the internal speakers.
Here is the output of that lspci:

According to [1022:15e2] you also need
https://linux-hardware.org/index.php?id=pci:1022-15e2-1022-15e2
Better install also sys-firmware/sof-firmware.
There is no gurantee it will work.
Try with
gentoo-kernel-bin
Can you please post your emerge --info?

Is this still an issue? Sound works on Steam Deck out of the box since kernel 6.1 and media-libs/alsa-ucm-conf-1.2.9

If you still have issues, check the versions, stop /etc/init.d/alsasound, delete the /var/lib/alsa/asound.state file and reboot.

More hints from my site you find in https://forums.gentoo.org/viewtopic-t-1157530.html
