I have just noticed that for some reason the sound is only coming out of the Right audio channel for my Tivo.

I have already checked the following:
1. The Sky decoder is definitely out putting left and right channels (or at least when I plug the audio directly to my TV I get sound out both channels)
2. I have checked the palmod_config settings, the audio setting were actually set to Dual Audio Input: Disabled, but changing that and restarting the Tivo have not helped.
3. I have check the Audio Cable that I'm using (it works fine with my DVD player)

At this stage I'm out of options, the only I can currently think of is my Tivo is a little sick and either the audio in or audio out is physically broken.

Does anyone have any other ideas?
