The next thing to check is if you're getting any AL errors (from 
alGetError). Since you say it works when both streams have the same 
format, but one goes silent if they're different, I'd check if maybe the 
stereo stream is getting confused from the other having a different format.

What do you mean by 'byte-tight'? I notice too the 5.1 stream has 148 
buffers queued with 106 processed, which is quite a lot (though that's 
not inherently a problem, it just looks a bit weird).

I could, although my main development system is Linux. If it's a Windows 
app, I'd have to run it under Wine to get useful info, which may or may 
not work.
