[PROBLEM] Popping sound during playback

[Tim Curtis]

The only diff would be that USB Audio device is on card1. I only have an old ODAC and so I don't know how other USB Audio devices might be named. The ODAC has the names "UAC1 DAC" and "USB Audio". Not very descriptive.

Code:

Card 1, ID `DAC', name `UAC1 DAC'
 Device 0, ID `USB Audio', name `USB Audio', 1 subdevices (1 available)

If u have a couple of USB DAC's, post the alsacap output.
