Hi everyone,
Based on the famous MSVAD sample, I developped a virtual audio driver which
gets audio data and sends it from kernel to user space where an application
of mine wraps the audio data and sends it over a network.
So far, it works as expected but I would like to make some changes to the
MSVAD audio filter graph to have something more related to what my
application is in charge of : audio playback only.
I guess I have to make a few changes to the WaveCyclic filter and get rid
of the capture pins and their connections to the ADC. It would let me with
a WaveCyclic filter with a sink pin, connected to a DAC, connected to a
source pin. If this I am correct and assuming that I want to get audio data
from any applications running in user space, what kind of sink pin should I
use, a bridge one ? Which one ?
I have almost the same questions for the topology filter. Assuming its
input pin is connected to the WaveCyclic filter source pin, which one
should I use ? As I don't want the audio playback to be sent to the
speakers while my virtual audio device is selected, which topology source
pin should I use ?
Thanks in advance for any help !
