There are 3 ways that you can support "multiple stereo pins". Each method will have a different result. 1) Multiple filters, each with a single stereo pin: This will be exposed as multiple devices in both the MME Wave API, and the DirectSound API. 2) A single filter with multiple stereo pins: This will show up as a single device in both the MME Wave and Dsound APIs. 3) A single filter with a single stereo pin that supports > 1 possible instance: This will show up as a single device in both APIs, but you will get multiple secondary Dsound buffers.

The thing is that even if we have set multiple in/out pins in KSPIN_DESCRIPTOR_EX the system recognizes only the ch. 1-2. That is logical as the system is still using the interface name and with that only ch. 1-2. Our wishes: We would like to create only 1 filter which would support multiple (stereo) pins. Filter(interface) is registered to KSCATEGORY_AUDIO, KSCATEGORY_RENDER and KSCATEGORY_CAPTURE.
