There's not much you can do if the app itself is misbehaving in this
regard. The best you can do is file a bug with the Real Player
developer and document the problem for your users.

One thing you might want to try is to build a version of the
AudioReflector driver from our SDK such that it's stream layout and

this is a problem with what your driver is doing or if it's a problem
with Real Player. The catch is that the AudioReflector driver doesn't
send the data to a speaker. The way to use it would be to set Real
Player to output to the AudioReflector and use another app to record
the input data from the AudioReflector. Then you can look at the
results in the file to see what you got.
Hi Jeff,
I tested the method you described (nice to be able to change the
driver stream layout in the info.plist file...) and yes the problem
seems to be in RealPlayer: the sound get wrong when recorded using
AudioReflector on a application: same lower pitch on one channel only.
So my guess is that RealPlayer is not able to correctly handle multi
(non-interleaved streams drivers when playing some files.
(Jean Pierre, I think this time we cannot do anything, only report a
bug at the appropriate place)
