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 :-) On Wed, Sep 25, 2024 at 6:33 PM Manuel Quintero F <man...@uas.edu.mx> wrote: > Hi, I compiled the mainline kernel 6.11.0, as a result the audio does > not work, I don't know if it is a kernel error.
