michal 2022-11-06 08:51 developer ~0070174	Note it is the same with MM4 and affects all formats, not only WMA. MM cannot mix audio, it only extracts left and right channel, when output is 2 channels.

jiri 2022-11-22 16:22 administrator ~0070421	Added 8->2 channels conversion, to be reviewed by Michal and if no issue found, other conversions can be added as well.

michal 2022-11-28 12:32 developer ~0070442	Fixed in build 2800. I cannot test it properly on >2 speakers, please try to test on more configurations.
