[QUOTE="davidf, post: 1021616, member: 19484"] Sadly I wrote that code so long ago now that I forget exactly what the difference was, but the channel layouts are different... [FONT=arial]In most media input channels and output channels are a direct mapping to the same number:[/FONT] {0,1,2,3,4,5,6,7} Input channel 0 is mapped to output channel 0 etc. [SIZE=3][FONT=Consolas][SIZE=3][FONT=Consolas]In one of the 5.1 setups (and I can't remember if this is surround or not) the channels are laid out as follows:[/FONT][/SIZE][/FONT][/SIZE] {0,1,2,4,5,3,6,7} where input channel 3 is mapped to output channel 4, 4 to 5 and 5 to 3. Got curious enough that I went and looked it up; [url]http://en.wikipedia.org/wiki/Surround_sound[/url] All the speaker setups are there (there are two 5.0 setups which can both become 5.1) in essence 5.1 and THX - you can count yourself lucky I removed the speaker lists once I realised it was THX :).
