Wierd Audio problem with Live TV

[Darkside]

Using a FlyDVB-T Duo on a P4 3 G with 512Mb ram.
Strange one this

Have got audio when playing files, even playing recorded TV files - good.

But when I try to use live tv the pictures there but no Audio, even stranger is that if I go to scan for channels, there is audio when I go in but not if I click on one of the scan results (audio goes off)

Any ideas?

Most strange thing is that there is audio in the tv recordings

Quck update, have managed to get audio back now after changing the audio settings to use my Audio card for output (third combo box on the playback tab (I think).

Weird.

i think PowerDVD must have changed something whe I had installed it.
