Hmm.. I'm trying to set the channel configuration programmatically, but fail ("The
property set specified does not exist on the object."), my code
for setting it is:
KSP_NODE node;
node.Property.Set = KSPROPSETID_Audio;
node.Property.Id = KSPROPERTY_AUDIO_CHANNEL_CONFIG;
node.Property.Flags = KSPROPERTY_TYPE_SET;
node.NodeId = 0; // KSNODETYPE_DAC
node.Reserved = 0;
KSAUDIO_CHANNEL_CONFIG config;
config.ActiveSpeakerPositions = pWFX->dwChannelMask;
fRes = DeviceIoControl(hFilter, IOCTL_KS_PROPERTY, &node, sizeof(KSP_NODE),
(LPVOID)&config, sizeof(KSAUDIO_CHANNEL_CONFIG), &dwBytesReturned, NULL);
What am I doing wrong, as I can see that my handler is called when I set the
configuration via sound control panel... ?
TIA
/Rob
