Title:
[regression][, Realtek ALC888, Green Line Out, Rear] Underruns,
dropouts or crackling sound
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
sound is crackling after upgrade to Oneiric.
this happens also in Precise daily image from 2012-01-26.
Actually only the right channel is affected. The left one works fine.
Stereo is therefore "crackling".
soundwise everything worked fine under Natty.
running Intel DQ67SW mainboard.
