I have not done careful timing, but I seem to gain about 5 seconds/minute. It is enough to make the audio very unpleasant when playing MP3s. >How-To-Repeat: Suspend and resume. Play audio >Fix: Only known work-around is a reboot. I suspect that reloading the driver would do it, but I have pcm in my kernel at this time. Will try a kernel without PCI when I get some time. I will admit that I can see nothing in the driver's resume code that seems likely to cause this, but I'm none too familiar with the code and probably missed something. >Release-Note: >Audit-Trail: >Unformatted:
