I think AC3 or FFD will help however from a different perspective - I run fox through my Happyi card but it all comes down in analogue and I take 7, 9, 10 etc of Foxtel. However I also run a HD box because I needed a backup and this runs direct into my amp with HDMI switching.

So from a non computer perspective HD 10 comes down in 2 channel dolby unless a rare movie event takes place - 9 til just recently is now in 5.1 - 7 is still in 2 channel ABC HD is in 2 chanell dolby but SBS HD has now enhanced audio and comes out in straight stereo - not dolby and they are different combinations.

What I am now wondering is if your difficulties are die to different broadcast streams from different FTA's in terms of audio - if that is the case then fixing becomes harding as you need to insure the processing meets this - but it may be a matter of AC3 not functionally properly - just some thoughts just to assist in the madness.

Hope you fix it.

Cheers
