Sorry, I wasn't really expecting it to work without further changes.
Being able to reliably detect the error would be a first step.
Though it might be possible to extend the MSGTR_AudioDeviceStuck case.
Either way, I did make some progress.
I noticed that "/etc/rc.d/sndio stop" actually doesn't work either,
but hangs for a long time and then says "failed".
And sorry, but for this I don't take the VM excuse, a server
that doesn't manage to terminate itself is just bad code.
However after manually killing the server, -ao sndio suddenly works.
No idea how or why so far.
I also didn't manage to test for the small issues I expect so far.
