If I do an strace on aplayer and look at its output after the resume
it looks like aplayer is hanging up on trying to read /dev/snd/timer
and is getting -1 EAGAIN (Resource temporarily unavailable) from it.
I would greatly appreciate any comments or suggestions of what I can
do next to further narrow down the problem
