My AVStream filter with capture and render pins (plus line-in and speaker pin = 4 pins total) and 2 nodes (DAC and ADC) isnt visible as audio device in a system without other sound hardware. I want to use this wave device for special purpose, so dont actually care about it being visible in volume control applet etc. I also dont implement topology filter or volume nodes (no hardware volume control is present anyway). Maybe for default (first) wave device volume control and topology filter are required? Does anyone know? What can I do to make my device visible for Wave API? with regards Konrad ****************** 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.de/
