Firstly I connect my PC via SPDIF

As the topic says, when I try to watch a channel that has AC3 audio (7 HD) I get no sound. If I start to record the channel or timeshift it the audio works, straight away I stop timeshifting or recording, the sound disappears again. Playback of files is fine also.

I have tried AC3 Filter, FFDSHOW AC3 codec & Cyberlink's one and get the same result in all. Graphedit shows the connections going all the way to my directsound device, I am at a loss. With the AC3 filter I will get a split second of sound when I change to the problem channels but then nothing.

Channel 7 Digital works fine but Channel 7HD has this issue for example.

Does anyone know what is happening?
