** Description changed:
The audio lags in rythmbox and on websites like youtube. on videos, the
image also sometimes lags.
running
pulseaudio -k
"solves" the problem, hence the assumption that this is a pulseaudio bug.
- Here's the hardware information(after having stopped pulseaudio), what
- type of additional information can I provide to help pinning this issue?
