FWIW, I have the same problem on my notebook (also Allegro-1),
but on 4-stable.  The problem exists for several years already
in 4-stable and hasn't been fixed yet.  I sent a PR long time
ago.

Every once in a while, right after booting the machine, when
I try to play audio for the first time, the kernel tells me
"play interrupt timeout, channel dead", and no sound is played.
Immediately rebooting again fixes it most of the time.

I even considered automating the process:  Playing a 1-second
audio file from /etc/rc.local, checking dmesg for the error
message, and initiating a reboot if necessary ...
