Ac3 audio not working

[thejoker]

I'm on latest vix build and no ac3 audio I working. On most channels changing to mpeg carries the narration option and on channels like BBC one HD there is no second option.

Is there an update, I've restarted, updated everything, checked tv settings. Def no ac3 setting working and pretty much all HD channels affected.

Eir sport 2 was only channel I could change ac3 to mpeg without NAR

Anybody know why ac3 could not be working. Is it a fault on the build ??

AC3 is fine on all my STB's.

All mine too apart from twin-oe, mpeg audio is fine but not all channels have mpeg and most of those that do have narration

How are you connecting your audio and video from the twin-oe? If it's HDMI lead direct to a TV, maybe the TV has ac3 disabled? It would probably be best to describe the signal path as, if there is an AV amp in the circuit it could be any number of things. It seems like a settings issue somewhere in the chain. Ensure DD is enabled in the AV settings on ViX and that you are not transcoding to some other format. I assume we are talking satellite channels here and not Freeview?
