Hi,
I have been running -current on my laptop the last couple of weeks and
after watching some videos I realized that audio playback is gone after
I suspended my laptop.
Reading through the code I arrived at this solution to restore audio
playback after suspend.
The patch has been tested on this card these last couple of days without
any issues.
