Maybe. In a WaveRT driver, which is how most HDAudio devices are
supported in Vista and Win 7, the kernel driver does not get involved at
all in the transmission of audio data. The audio engine process in
user-mode copies data into a circular buffer and moves the pointers on
its own. In that case, it's not clear there's anything for you to filter.
With WaveRT, there is no possiblity. As Tim states, the user-mode application
gets a shared buffer
with the WaveRT driver and outputs audio directly to the device. There is no
way to intercept that.
