So the input of the GFX is 2-channel, and it outputs 4-channel, which goes to some hardware processing below the Kernel Streaming transition, which eventually folds it down to 2-channel again? -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Robert Bielik Sent: Monday, August 25, 2014 5:26 AM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] GFX changing channel count? Hi all, Is it possible to create a GFX that changes the number of channels exposed by the HW driver towards the audio engine ? Requirements: A speaker endpoint with stereo output, but with GFX that processes those 2 channels to 4 channels going to the sound hardware.
