Multimedia :: no sound

I have a Plantronics DSP headset and I want to use it with SJphone. I can't get audio in or out from the DSP on the SJphone, but I DO get audio on the headset from XMMS. I notice that both are using the same device../dev/dsp...but again...no audio on the sjphone. In fact...I cant get audio on the sjphone with the on board sound card either. However..as a reference, I DO get audio and CAN use the headset (mic too) when running Ubuntu.

Any clues as to what might be wrong??
