No audio after complete reinstall

[Shader]

I completely reinstalled my htpc server due to virus infections.
- new windows xp pro
- New .net 2.0
- latest drivers (PVR150)
- latest gbpvr (97.09)

Everything seems to work fine om my MVP except for live-tv and recordings.
I cannot seem to get any audio from my tv channels.
I get audio from old tv recordings, mp3, etc. but not from TV.

I've tried several drivers for my pvr150 but they all do not seem to work.

It had been working for 1,5 years before the reinstall.
I lately used GBPVR 95.16

I've got my hands in my hair... does anybody have a solution?

Missing audio can be pretty common for PVR150 users. All I can suggest is trying different versions of the Hauppauge drivers.
