Fresh install - no audio - change audio driver?

As the title says, fresh install, no audio. I believe, from my travels through the forum, that the source of the problem is the wrong audio driver. I could be off track here as well of course…

From the system dump I have the snd_soc_skl installed but from similar posts there seems to be a better driver specific to my Apollo Lake chip set: snd_sof_pci_intel_apl.

2 questions,

  1. am I on the right track?
  2. if so, is it a relatively simple matter to update the driver?

Bumping this post.

Researching and not finding out how to change the default audio driver. Would love to hear from anyone regarding the first post question: Should I change my audio driver to snd_sof_pci_intel_apl??

I have recently tried mhwd -lh -d --pci, and it seems snd_sof_pci_intel_apl is installed.

How do I set it to the default?

$ mhwd -lh -d --pci

Thx to anyone who can help with this.

Well … we can try and do what you think should be done:

sudo modprobe -r snd_soc_skl
sudo modprobe snd_sof_pci_intel_apl

Also … look around in alsamixer.

Information from suggests driver snd_sof_pci_intel_apl has been superseded by snd_soc_avs
But there are only 5 hardware scans posted for Google Baybytiger systems. 4 scans do not have any ALSA data and the 1 scan that shows ALSA data is from Dec 2022 for Kernel v5.15
