Finally got a digital reciever to act as a go between for my older coaxial standard 5.1 cinema sound system and my newer optical sound standard DVD recorder.
Everything worked great when we first put it all together but now it's developed a high pitched whine that won't go away and it's really annoying. We thought it might be the optical cable but it was fine to start with.
The whining pitch also differs depending on what channel we're watching too, on one channel it's not very noticable but it is unacceptable on all the other channels and DVD's.
Any suggestions as to what it is and how we can sort the problem..?

My suspicion would fall on the digital receiver translating the optical from the DVD player to coax. Optical cables themselves could not introduce such a sound, but crosstalk and instability in the receiver could. There are devices available that will convert digial to coax, or coax to digital; they are designed to do that job only and work well. However, I agree there is no real reason to prefer optical over coax connection for you audio, unless your DVD player doen's have a coax output.

Search for an output setting on the DVD player that you can play with, see if that helps. Make sure the digital input setting on the receiver is set to the correct input. If all else fails, go back to using a coax--I've never heard from any audiophile that they can tell a difference.

agreed there is no difference in the data sent coax or toslink cable, its just sent differently. some might say the optical will go farther but I have a 150' section that I have to amplify after the run.
