Though it would be better if you did 1 split as 1 patch, with 2 patches
in total.

It doesn't have MBIAS either. Please split it out as well.

How does that relate to the rest of the serie, which seems to be about
the audio on V3s?

This should be clarified in a cover letter, but you know that already.

There's not a lot of endpoints indeed, but you need 28 vchans (2 *
14).
