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. -- Dan Aloni
