Hi, I have a virtual audio microphone based on MSVAD. I use DirectShow to enumerate devices and I want to exlude my driver from the list. I do not think that FriendlyName from PropertyBag is a good way for filtering, so I started to look for more precise way of doing filtering. AFAIK, FriendlyName will be different with different system languages, so my question is - how can I get unique device identifier while enumerating with DShow for not to show my microphone along with other mic devices on the list? Thank you, Anton.
