Xitel Pro Hifi-link playing mono, not stereo (Fedora Core 6)

[martin <martin@xxxxxxxxxxxxxxxx>]

Hi,

I have a Xitel Pro HiFi-link usb soundcard which works fine in Linux, 
except that it appears to be sending the same signal to both left and 
right channels.  If I start up e.g. Audacity, import a track and pan it 
all the way to the left or right it still plays in both channels.  The 
same thing happens in Ardour so I don't think it's a software specific 
thing.  I've had this problem in FC5 and FC6.  The sound was fine before 
that (FC4 I think).  This is my first time playing around with Linux 
audio so if anyone could suggest how to start fixing this I'd be 
grateful.  I can post any log/config files.

Thanks,
Martin
