I was wondering how I can select the output device for audio in directshow. I am able to get available audio output devices in directshow. But how can I make one of these to be audio output device. Its always going for the default audio device. I want to be able to output audio on my choice of device. I have been struggling through google but couldn’t find anything useful. All I could get was this link but it doesn’t really solve my problem.
Any help will be really helpful for me.
It is up to user to manage audio devices and choose a primary device (such as via Control Panel applet). You can find ways to switch devices programmatically in Windows XP, however in Vista+ it is impossible without interactive user action by design.

UPDATE: The mentioned above refers to modifying system configuration trying to alter default audio output device. An application is however not limited to default device only. Instead, it can enumerate available devices (see Using the System Device Enumerator +
CLSID_AudioRendererCategory) and then create an instance of renderer for specific device withBindToObjectcall. From there on, it is a regular filter, just bound internally to device of interest.
