Bug Description
continuous crackling sound from moment ubuntu starts up.
no sound problem in Windows before Ubuntu install (ubuntu great btw)>
not only green line out, rear ( I use this one for speaker); all sound device.
crackling continues when pulseaudio turned off,
when playing sound gives interruptions.
Continuous switching between speakers and headphones in sound settings.
Difficulty adjusting sound levels in alsamixer
tried editing sample rate in daemon.conf or tsched=0 in default.pa, checking archlinux and some other basic bug sollutions for ALSA, but no luck..
there's a short video I made of the problem:

thx
