By external audio do you mean that when you play TV you don't get any sound
I had the exact same problem, and it is due to either the order of loading
the modules, or which module files exist on your computer in what locations.
Let me know, and I can send you my startup script.

Thats exactly the definitive answers I was looking for :-))
All I need to do now is get external sound going (to complement the s-video
input) and the radio (which scans OK & finds all the stations I'd expect it
to) which also has no audio :-((
