Not sure if it's right (or allowed) to post a different patch as attachment, 
but I have been using a different audio configuration (see attachment).
I haven't yet tried if/how it works via HDMI yet, but the speakers and 
headphones work fine.
This patch is based on the following commit:
https://github.com/TuxThePenguin0/linux/commit/
872b829a3511cfa853bd3af3bd4f30be1cb3d1ab

I've added 'Danct12' to the To list as they are the maintainer of the primary 
PT2 image and we worked together to get to this audio config.
I don't if they still use it.
(I've been using my own kernel/image for a while now).

Cheers,
  Diederik
