Testing 6.11.0 - No audio

[Aruna Hewapathirane]

It looks like there are a few potential issues contributing to the sound
problem:

   1.

   *ALSA not detecting sound cards*:
   The message [ 0.461483] No soundcards found indicates that ALSA
   (Advanced Linux Sound Architecture) didn't detect any sound devices. This
   might be due to a missing or incompatible kernel module or driver.
   2.

   *snd_hda_intel codec probe failure*:
   The line [ 0.473025] snd_hda_intel 0000:00:1f.3: Cannot probe codecs,
   giving up suggests that the Intel HD Audio driver (snd_hda_intel) is
   unable to properly communicate with the audio codecs. This could be due to
   missing firmware, an incorrect configuration, or a regression in the kernel.
   3.

   *Malformed or invalid regulatory database*:
   The message [ 0.461769] cfg80211: loaded regulatory.db is malformed or
   signature is missing/invalid indicates that the wireless regulatory
   database is malformed or invalid. While this affects Wi-Fi, it could
   indirectly affect audio if there’s an interaction between the kernel
   modules (such as shared interrupts). This might need fixing too.

Run: *ls /boot/config-*.**  it will show you a list of all config files you
have. I would roll things back to a config where you know for a fact sound
worked. Then once I have the sound back up and working I would use 'this
sound is working config' and copy it over to build the new kernel ensuring
sound will be there.

You can also try: *sudo modprobe snd_hda_intel*

Happy troubleshooting :-)
