A project I started when in HK due to a need for Alex to connect lib_i2s 4b to UA. This worked but was quite messy. This API allows UA to be easily tacked on to existing audio systems which already have their own main and audio hub and hides the details of endpoints, channel connections and general guts of the USB side of the XUA. It includes abstracting the custom low-level channel protocol over c_aud which is easy to get wrong, especially if SR change support is needed.
Some background behind it here.
