Comment (by cehoyos):

 (Unrelated: On your Ubuntu installation, you did not test FFmpeg...)

 My only remaining advice is to remove {{{flags = SND_PCM_NONBLOCK;}}} from
 line 193 in libavdevice/alsa-audio-common.c
 Since the non-blocking mode works for everybody else (with very different
 hardware and drivers), it is not very likely that there is a bug in FFmpeg
 and if there is a bug, it is unlikely that we will be able to fix it.
 Were you able to test on different (but identical) hardware?
