Figuring out /dev audio devices
 

I'm trying to use a VoIP application in Linux called SJPhone w/ a stanaphone account. I have it all configured right where I can make a call and the phone rings but I have no audio incoming or outgoing.

In the application it set my audio device to /dev/dsp on both the mic and speakers. I'm figuring this is not right cause 1. There is no dsp in my /dev directory and 2. becacuse the application isn't working.

Any help in figuring out which /dev device is my sound card?
I tried checking other audio applications to see if it would tell me, but no luck.

Thanks for your help and suggestions.
