I recently had a Mark2 tuner installed. I live in NZ, so it was not done by Darren. The tuner picks up PAL channels fine (well 2 anyway, as my frequencies are different to the setup on the image) and I will need to retune.
Anyway, the Tivo starts up and I get sound playing during the animation. I go to watch live TV and the video is fine, but there is no audio.
I have copied the palmod_config and palmod.o files across, and set the tuner type to be ALPS/samsung with the location of NZ (in actual fact the tuner type is listed as samsung).

But still no sound! - argh! Any help or suggestions would be appreciated.

I did not replace the Micronas chip as I was resigned to the fact that in NZ with a US series 1 Tivo and a FTA tuner, mono is the best I can hope for.
