[L2Ork-dev] RPi3 l2ork installation

Tue Feb 14 16:03:01 UTC 2017

Ok I will have a look tonight, I didn't try adjusting the buffer or
anything, just pressed go basically :) A quick question for you if you
don't mind - I was thinking about using a DAC expansion for the Pi like
this:
https://shop.pimoroni.com/collections/raspberry-pi/products/phat-dac#shopify-product-reviews
- lots of people seem to think that resolves the inherent noise issues that
the Pi built in jack has- but is it compatible with PD? I'm not sure if it
behaves like a sound card per se.

warm regards,

Aidan
