Hey folks,

Entirely unrelated to the regression on this board that we dealt with the other week, I have (and have had for a bit), a problem with audio on this laptop. After a while of use, I'll have a problem like this:

With those last 4 messages repeating constantly (~3 sets per second, and the above are from v4.13, but I've had similar for as long as the driver has been mainline I think) and it only stops when I reboot. Rebooting may or may not clear the problem, last night I had to power off to get audio to come back up. I'm not quite sure where to begin debugging this issue. Does anyone have any suggestions? Thanks!
