Using USB sound in Ubuntu

[Jerry Matheny]

Can anyone help me out? I need to use Ubuntu or GRML live cd as a  
method for recovering data on my desktop, however neither one of them  
seem to detect my on board sound cards by default. Is there a way I  
can have it work with my Plantronics DSP 500 USB headset instead then  
so I can get speech? I don't have a hardware synthesizer otherwise I'd  
use GRML with that. Any help or suggestions would be appreciatd.


Thanks in advance,

jerry
