[QUOTE="red_zebra, post: 539882, member: 97560"] No, not really. I have connected my Hifi-amplifier to the SPDIF-port, so I can switch my Hifi on to enjoy full 5.1-sound of DVDs or avi-files with multichannel-AC3-sound. My TV is connected with a jack-cinch-cable to transfer stereo signals to the TV-speakers. What I want is, that the sound of all AC3-files is tranfered to the TV as well as to the Hifi, so I can decide for every playback, if I 1. turn on Hifi and mute the TV to listen to the sound via Hifi or 2. just playback the sound with the TV-speakers and let my Hifi turned off. Therefore the multichannel-sound must be downsampled to stereo and has to be transmitted via the audio jack. yes, completely right. This is the way I am using it at the moment. If there is an analogue signal, it is amplified by the TV and I can use the TV-speakers. But once there is a digital AC3-signal, there is nothing to hear by the TV-speakers and the only way to playback this sound is by switching on the Hifi. It doesn't matter if I switch SPDIF on or off in the sound driver - there is still no signal on the audio jack after switching SPDIF off (so in this case I have no sound at all). And it doesn't matter which audio jack I connect to the TV (there are 4 - front, rear, center/sub and side) - there is no signal on any of them. No. I just can switch on or off SPDIF. But as I mentioned above, there is no difference between switching on and off SPDIF - there is still no signal on audio jack when I play a file with AC3-sound (no matter how many audio-channels the file has). I hope this explains my problem a bit better. And by the way: Thanks for your help! [/QUOTE]
