A09 Vantec NBA-200U 7.1 USB Audio Adapter

Description

This is a Vantec NBA-200U USB 7.1 audio adapter - will work with Mac/PC/Linux and at one point we had this working with a Nintendo Switch via USB on the dock.
Does not require any external power, just plug into USB, and add your input or output devices via analog 3.5mm jacks, SPDIF TOSLINK optical.
Was working when last used but has sat in a box of electronics for a few months.
