No sound from AverTVHD Volar Max

[lunarlightning]

I just pick up an AverTVHD Volar Max, it's media center is crap, and only picks up half my channels, so I decided to give GBPVR a try.

Cool software, nicely done! Picks up every channel I'm expecting, unfortunately there is no sound. The AverMedia center does have sound for the channels that it will tune.

System stats:

Windows XP SP3
GB-PVR v1.3.11, fresh install, no extra plugins added.
Comcast Digital Cable, channels scan as QAM AC3
For device type I click 'Only Show devices detected' to true and selected "AverMedia H826 Hybrid Volar Max (QAM)"

Any help would be appriciated.

It'll probably just be a case of not having an appropriate decoder installer. Try installing AC3Filter. http://ac3filter.net/

Thanks, that did the trick!
