2. Mplayer will not (as it shouldn't) allow you to pass undecoded AAC over spdif. Mplayer will decode all audio except for AC3 or DTS with the appropriate -hwac3 or -hwdts switch.
I can pass undecoded AAC to my receiver and i listen just noise

3. To play aac over spdif it must be decoded and downmixed to 2 channels (spdif only supports 2 channel pcm).
Why? My soundcard Audigy2 supports raw AC3, pc -> ac3 ->receiver works, I'd like to do:

pc -> AAC -> ac3 ->receiver

4. AFAIK, There is no way using mplayer or any linux player to transcode to AC3 and pass over spdif on the fly. It might be possible with gstreamer, but it would be difficult at best.
Thank you for your clearness, I found http://essej.net/ac3jack/ but I don't know how to use this tool for what I'd like to do
