It sounds like you are using Windows Media Player (WMP)? For troubleshooting
purposes, please try to play the 6- and 8-channel files using sndrec32.exe
(you'll have to copy from an XP machine because it no longer ships with
Windows).
Thanks.

Hello Mitch,
Hello Philip,
I managed to implement _PIN_PROPOSEDATAFORMAT now.
I accept dwChannelMask = 0 or KSAUDIO_SPEAKER_5POINT1 or
KSAUDIO_SPEAKER_7POINT1.
This is what I observe:
-the speaker setup shows the 7.1 format (before it showed 5.1 only).
-on the advanced page there are more formats available, including 6
channel and 8 channel formats.
-pressing the test button results in a playback of 8 channels or 6
channels :-)
-But the 6-channel test file still can not be played through the line
outputs :-(
-The same for the 8-channel test file and the speakers :-(
I'm getting the message "An audio codec is needed to play this file.."
any ideas?
thanks,
/Uwe
