Well I've re-typed the unit and reloaded my config. No good. Sound still coming equally from all speakers. I tried other DSPs and get the same. Seems to be OK via HD621.

Have I somehow fried my unit (or at least the USB card?) I've double checked to ensure I have the latest USB driver. I'm getting a little worried!

Thanks,
John
