Hi guys I have a small problem here: I have just added mono support to our driver ->done a test in Wavelab and dwChannelMask is still set to KSAUDIO_SPEAKER_STEREO. nChannels gets 1 as supposed to, but now how should I know which channel to open if it still wants to open a stereo channel? Is there a default one->like left or is there something else here?
