Hi all, Quite some years have gone since I asked this question the first time, and corresponded with Frank Yerrace on the subject and our product. At that time, to my great dismay, we opted for a VAD solution which of course requires a LOT more work than simply producing an APO. I wonder now if there has been any change in policy, if this can now be done with a "blessing" from Microsoft ? :) Reference: //www.freelists.org/post/wdmaudiodev/Device-neutral-GFX,11 Regards /Robert Bielik Senior SW Engineer Dirac Research AB ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
