I had a good idea last night... I thought I would try RTFM ;) Turns out the manual for my telly explicitly says that it doesn't output 5.1 via the optical output :(. The optical out is 2 channel only. Bah! If only I'd thought of reading it prior to buying the 5 meter optical cable, I could have saved money and bought the 1 meter version instead! Guess I will need to buy a 5 meter stereo audio cable to run from the stereo audio out phono jacks back to a simple stereo in on the amplifier for TV sound (amp only has 1 optical input, which the pc will use). I very much doubt Samsung will be able, or want to fix this with a firmware update! Especially as it is doing exactly what the manual says it will do :). It is a real shame as it would have been perfect given the layout of my room - with TV on one wall, but the AMP, PC etc. on a shelf else where in the room, as it would have been simply 1 HDMI cable to the telly, and one optical cable back again. Amp would then pretty much permanently stay in 1 digital mode regardless of the sound source, now I will have to switch between digital or analogue depending on what I'm doing - ah well. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
