It turns out that it works only after the first boot when the previous recipe[1] is applied. After the second boot, it stops working. Shortly I'll attached some preliminary forensics: alsa-info.txt and output from 'alsactl store'. One key observation is after the first boot (when the mic works), /var/lib/alsa/asound.state is empty (zero-length). After the second boot, the file has content. ::: Recipe ::: cd /var/lib/alsa mv asound.state ~ fuser -k /dev/snd/* # Remove parent device /sbin/modprobe -r snd_sof_pci_intel_cnl mod=$(grep -m1 -E '^(snd[^ ]*|ac97_bus) [0-9]+ 0' /proc/modules) while [ -n "$mod" ]; do mod=${mod%% *} /sbin/modprobe -r $mod mod=$(grep -m1 -E '^(snd[^ ]*|ac97_bus) [0-9]+ 0' /proc/modules) done rmdir card0.conf.d # Should be empty ls /var/lib/alsa # confirm no cards listed cat /proc/asound/cards reboot -- You are receiving this mail because: You are on the CC list for the bug.
