There are multiple reasons why ALSA or our ALSA backend might return
EIO to the application. From this remote perspective it is not really
possible for me to find out what the exact problem is.
Please install the debugging symbols for alsa-plugins and use gdb to
find out what the reason for the EIO might be.
Does Asterisk call snd_pcm_recover() after getting the EIO?
