|Summary||0003362: Support multichannel tracks|
|Description||Currently we don't support well multichannel tracks, e.g. 5+1 channel tracks aren't properly recognized (i.e. shown correct number of channels) and there are possibly even problems with playback (to be tested).|

||Assigning to Pavel to fix as much as possible, mainly support of AAC and possibly even OGG. Let me know should there be any things to be fixed on my side.|
||Michal, please review how much still needs to be resolved here.|
5.1 channels are recognized properly.
1) There is a problem with conversions - covered by issue 0006609
2) Playback using out_MMDS does not work in Win7 - covered by 0006447
3) WASAPI output plugin plays only 2 channels and discards the rest. This is probably problem with downmixing procedure, the same behaviour occures with converting 6ch video to 2ch (the same downmixing procedure). The procedure should be improved to mix channels, not discard.
4) There is a problem with AAC 5.1 playback, MM does not play the sample file. It is because in_mfaudio fails to play it. Without in_mfaudio.dll, MM plays the file using QT.
||4) fixed in build 1378.|
||All should be fixed in build 1381. I've inserted mixing issue (3) separately as 0007884|
