I'm using this for my test signal: http://www.csy.ca/~shane/51test.wav when using: aplay -D hw:0,3 51test.wav Front and rear left and right are correct but centre is missing. The order in the wav is: front left centre front right rear left rear right sub buz When using mplayer: mplayer -ao alsa:device=hw=0.3 -channels 6 a51test.wav The channel mapping is totally wrong, centre comes from rear left etc. The missing channel under mplayer is rear left. I get the same mis-mapping playing the original (51test.ac3) with ac3dec -D hw:0,3 -6 51test.ac3 but playing the ac3 directly in spdif mode: mplayer -ac hwac3 51test.ac3 Works fine. I've no idea where this problem lies, IE in alsa's channel mapping, the Intel driver or the way liba52 is decoding an AC3.
