When calling IMMDevice::Activate you have an option to provide parameters that point to a specific session you need. Having it NULL you would be attached to default session.

guidAudioSession

Session GUID. This member is a GUID value that identifies the audio session that the stream belongs to. If the GUID identifies a session that has been previously opened, the method adds the stream to that session. If the GUID does not identify an existing session, the method opens a new session and adds the stream to that session. The stream remains a member of the same session for its lifetime.
