Comment 10 for bug 388081

Still having this problem with lucid and my USB DAC. Here's a more minimal set of messages. The underruns occurred about 5 minutes into playing the first song of the day with Rhythmbox. The audio effect was a sort of "stutter" in the music.

I would be pleased to run apport or any other testing required!
