Comment # 2 on bug 1039441 from Michal Suchanek

I tried some debugging guide after some fiddling I got into a state when
pulseaudio was still not working and aplay was failing due to device busy.

Unfortunately, I already got the system into working state so I cannot recheck
I had the correct device and whatnot.
