No its only when it uses dolby digital signals which are foxtel hd channels, anything else using another audio source is fine. I can swtich the decoder to Neo or Pro logic etc and its fine. As soon as it goes to a HD channel and converts to Dolby Digital the issues appears.
I switched foxtel between mpeg3 and ac3 audio, same thing.
But i think i know what it might be after more research. I have the arc setting to on, so it maybe receiving the tv audio output feeding it to the amp. The amp is basically getting 2 signals (the Foxtel and the TV) and as the tv doesnt output 5.1 this is causing it to switch between Dolby Digital (Foxtel) and the decoded audio from the TV(Neo, Pro Logic etc.)
Its not doing it on other standard def channels since it cant decode to Dolby Digital as they are standard def channels so it decodes to Pro logic or whatever I chose and there is no issue. As the TV audio signal to the amp is also 2 channel on standard def it doesnt need to switch..
What is odd is that it's not doing it on some HD channels. But this seems to be the only thing I can think of. There is no error message. The foxtel uses optical out direct to the amp along with the hdmi cable, so the TV is essentially getting the audio feed from the Foxtel optical and the HDMI from the TV (using arc).
When i get home i will turn it off anc hopefully it works.
