Yeah, I understand. I also remember these issues with `pulseaudio' when 
I did my tests. ISTR that starting the daemon with `--exit-idle-time=-1' 
and `--allow-exit=false' avoided the daemon to stop as you mention.

However I think these issues are not related to the `Illegal 
instruction' crashes. Did these crashes still occur when using the 
analog device as a sink?  For me, these crashes were linked to the HDMI 
audio output device.

Kind regards,
