Btw, there is a method called something like "HardwareSupportMask" that will return whether or not there's a physical hardware control backing the operation. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Frank Yerrace Sent: Friday, December 01, 2006 3:02 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: Does a Microphone (Vista Audio Endpoint) have volume and mute controls Do you really need to know if the *hardware* supports these controls? If the hardware does not support volume or mute controls then the audio system will provide them through software. You can activate IAudioEndpointVolume on microphones. See http://msdn.microsoft.com/library/en-us/CoreAud/htm/endpointvolumeapi.asp. We expect very few apps to actually need these functions though.

Is there a way in Vista to determine if the microphone supports these controls?
