I can`t describe it any other way!

Basically, I changed the way my Sky HD audio output is connected to my amplifier.

Initially it was by phono leads but I kept getting this crackling / interference type noise especially when music was being broadcast.

I now have it connected via Optical lead and this seems to have resolved the interference noise.

Now though I have this boomp noise which emits from the subwoofer every time I change channel.

Its not a loud noise but its becoming annoying especially as I continually change channels when the pesky adverts are on every 10mins!

Any ideas as to how I can resolve this?

I get the same thing when I switch between DD and stereo programmes, not sure if it can be stopped. If I switch inputs, the amp mutes momentarily.

Maybe you should use your Sky HD to timeshift everything, rather than watching live programming. Saves channel hopping during adverts - just fast forward through them.

I do try and time shift as often as possible but its those occasions when watching something live that I end up channel hopping!

I just wondered why I wasn`t getting the boomp noise when I had the connection via phone leads

Because the phono leads only provide a stereo signal. Your AV amp/home cinema system receives a constant stereo signal through the phono leads, so it's not switching the DD/5.1 decoder on and off when you change channels.

With the optical connection, each time you change channels the DD/5.1 signal momentarily drops. The amp switches the decoder off, then back on again when it detects the DD signal, causing the noise.

That's my understanding of what's happening.

Ah Ha, I knew someone would know. Thanks
