This is when you use lsof/fuser to identify which process is hogging
the device. For debugging you should use something dead simple like
aplay in the host too. Also try configuring the programs/alsa to use a
dmixed plug explicitly. Have you tried using the device from two
containers (and not the host)?

If neither of that leads to a solution, I would ask alsa people.
