Title:
High frequency audio is distorted
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Ever since a recent software update (within the last month or so),
audio quality is terrible. I've plugged in various sets of speakers,
and the quality is consistent, so it's definitely a software bug.
The distortion is in the higher frequencies, and might be describe as
a whine or a buzz.
