That's great news!

Yes, that's the easiest way to do it.

Looks good. You can specify the format you need in the constructor,
and the buffer callback function will have the same format.

Yes that should work if you fill every second int16 with 0.

Ok.

Something is wrong, but I don't know why.

The data above looks ok.
Can you post a small sample program source code that shows the problem?
The BSoundPlayer with the new media kit is already working ok,
just in case the R5 one has a problem.
