It kind of works... I can play two MP3s at the same time to 'channel12',
and I can play one MP3 to 'channelALL' and hear it on all output
channels. But, if I play one MP3 on 'channel12' and another on
'channelALL' it sounds horrendous (i.e. popping and screeching).
It is not super-important that this works... I can work around it in my
software. I want to overlay speech on top of MP3 but I can just have
the speech engine create a wav file and then play that to each of the
four output channels separately.
