Hi Bart.

I just have a simple user setting for you to check.  Could it be that the
Advanced Audio Properties for the device are set to a stereo speaker
configuration?  If so, perhaps some of the applications you mentioned rely
on it while others might not.

Regards,

Joel

Subject: [wdmaudiodev] Multichannel audio device seen as stereo


Hi,

I have a 8 channel audio device with a KS driver based on the msvad example
from the DDK. Some DVD players, like WinDVD and MaximusDVD, only give me
stereo output, others like PowerDVD and DirectDVD give me surround output
with the same driver. In both cases I see that KS gives me 8 channels, as
I requested in DataRangeIntersection but for some reason the players believe
it is only a stereo device. Does anybody has a clue what could cause this?

Regards,
        Bart
