[In order to look into the crash, a backtrace would be nice to have
(don't forget to install debug symbols of all the relevant libraries)]
Why are you using arecord? That way you bypass PulseAudio completely
and record directly from the alsa sound source. Using parec instead
gives you all the pulse goodies you can handle!
If you're saying (I'm not quite sure I understand correctly) that
changing mute/volume of the pulse source does not result in a volume
change of the audio output of arecord, then that's completely
expected. (Well, it could have some effect, if pulse decides to adjust
hardware volume, but anyway, it won't be exactly how you want it)
