| 1) Verify from a cold boot whether the symptom is reproducible.
It is.
| 1A) If it is, upload the current state file
(/var/lib/alsa/asound.state) as an attachment to this bug report.
Attached.
| 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].
Done
| 1C) Then, reload the driver [sudo modprobe snd-intel8x0], and verify
whether the symptom is reproducible (no need to reboot).
This breaks... after reinserting the module, I don't get my /dev/dsp
back and I find the following in dmesg
