Title:
Crackling audio on HP / AMD Hudson machines when changing volume
during playback
Status in HWE Next Project:
New
Status in “linux” package in Ubuntu:
In Progress
Bug description:
We discovered that for these machines we would sometimes lose an
interrupt if we changed volume during playback and that enable_msi=0
would fix this issue.
This bug is for tracking purposes, please do not triage.
