Pinnacle Studio PCTV USB 2.0 tv tuner , no sound .

[Kostas Sfakiotakis]

I have the above named tv tuner card ( which has usb connection ) .
I can tune to any tv channel that i wish but the problem is that
i can´t hear any sound . lsusb would print


Bus 001 Device 002: ID 2304:0208 Pinnacle Systems, Inc. Studio PCTV USB2

The output of lsusb -v concerning the above tuner is a bit more
lengthy so i saved it in an Xemacs document and attached it to this
email . The problem with the sound is persistent and it can´t be
resolved by changing the application that am using ( the same problem
exists with both Tv Time and xawtv ) . I was wondering if someone could
give me any pointers on what course to follow in order to find the exact
problem and resolve it .
