<div dir="ltr"><div><p>It looks like there are a few potential issues contributing to the sound problem:</p><ol><li><p><strong>ALSA not detecting sound cards</strong>:<br>The message <code>[ 0.461483] No soundcards found</code> 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.</p></li><li><p><strong>snd_hda_intel codec probe failure</strong>:<br>The line <code>[ 0.473025] snd_hda_intel 0000:00:1f.3: Cannot probe codecs, giving up</code> suggests that the Intel HD Audio driver (<code>snd_hda_intel</code>) 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.</p></li><li><p><strong>Malformed or invalid regulatory database</strong>:<br>The message <code>[ 0.461769] cfg80211: loaded regulatory.db is malformed or signature is missing/invalid</code> 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.</p></li></ol></div><div>Run: <b>ls /boot/config-*.*</b> 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. </div><div><br></div><div>You can also try: <b>sudo modprobe snd_hda_intel</b> <br></div><div><br></div><div>Happy troubleshooting :-)<br></div><div><code class="gmail-!whitespace-pre gmail-hljs gmail-language-bash"></code></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 25, 2024 at 6:33 PM Manuel Quintero F <<a href="mailto:manuel@uas.edu.mx">manuel@uas.edu.mx</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi, I compiled the mainline kernel 6.11.0, as a result the audio does<br>
