The first step is to see whether it's a stale state file or an actual
code (if so, likely sound/pci/ac97/ac97_*) regression:
1) Verify from a cold boot whether the symptom is reproducible.
1A) If it is, upload the current state file (/var/lib/alsa/asound.state) as an
attachment to this bug report.
1B) Then, close all applications holding the sound device, unload all alsa
modules and forcibly remove the state file [kill $(lsof -t /dev/dsp*
/dev/snd/*) && sudo modprobe -r $(lsmod |grep ^snd |awk '{print $1}') && sudo
rm -f /var/lib/alsa/asound.state].
1C) Then, reload the driver [sudo modprobe snd-intel8x0], and verify whether
the symptom is reproducible (no need to reboot).
1D) If the symptom remains reproducible, then we'll begin the bisect procedure.
