Has I said in this post: http://forum.doom9.org/showthread.php?t=107718 it is possible to play 5.1 sound in a web page with quicktime.

Recently I tried on vista and... it does not work ! even with a simple 5.1 WAV file instead of a MOV with 5.1 AAC.

Vista + SBLive 5.1 + quicktime 7.5.5 => 5.1 is downmixed in stereo
Vista + Aureo USB MKII + quicktime 7.5.5 => 5.1 is downmixed in stereo
XP + SBLive 5.1 + quicktime 7.5.5 => 5.1 is correctly played

if I play the 5.1 WAV file with winamp under vista, it works, and
it works also in iThune ! Can you believe this ?!

All the conf is properly set (output set to 5.1) but it stay in stereo.
May be this is a driver issue, may be not...
My vista is on a laptop, so there is two soundcard detected: the stereo built-in card, and the 5.1 card on USB.

any ideas ?
