It shows 6 triplelets of input terminal, feature unit, and output terminal,
and they are structured like this:
IT[7] -> FU[19] -> OT[13]
Line-in USB Streaming
IT[8] -> FU[20] -> OT[14]
Rear Mic-In USB Streaming
IT[9] -> FU[21] -> OT[15]
Desktop Mic USB Streaming
IT[10] -> FU[22] -> OT[16]
Headphone Speaker
IT[11] -> FU[23] -> OT[17]
USB Streaming Headphone
IT[12] -> FU[24] -> OT[18]
USB Streaming SPDIF interface
Not sure how to make sense of that to a usbmix_name_map array and/or
usbmix_connector_map array combination that works. My trials so far
have not yielded a good result.
