USB DAC doesn't receive audio

Hey all,
I recently went ahead and installed openSUSE 11.1 on my laptop. I’ve been trying to get my USB DAC working so I can get some quality music. The DAC is recognized and I can select it and adjust the volume but I just can’t get any sound to come out of it. I’m no linux pro (obviously, since I can’t figure this out) but I can follow directions well and I have no problem working in terminal with some help on what to do.

The funny thing is, the sound was working for a while at one time and then it stopped.

I think this info may be helpful, so here it is;
the laptop is a Sony VGN-FZ340N
the USB controller chip on the DAC is a Burr-Brown PCM2707

I didn’t think this belonged in the laptop section but if it does please move it or let me know so I can post it up there.

Any help is greatly appreciated. Please let me know if more information is needed to help me.

A DAC is not a headset … still, is there anything here that helps:
USB headphones - openSUSE

I do not have any USB audio devices so I can not provide any support.
