[PD] UA-25 on RPI

For what it's worth, output did work using:
pd-extended -nogui -noadc -audiooutdev 3 test.pd
with 3 being the direct alsa interface as opposed to the alsa plug interface.
It's when I enable the audioindev that I get crackles. I know there are people out there using the UA-25 + jack, but I never needed jack before with an embedded setup.
Part of the issue might be the RPI's real-time kernel. My old wearable setup was far more unstable with a realtime kernel and using a regular kernel with realtime permissions for PD worked far better.

Ideally, I want 2 in / 2 out and this audio interface has worked wonderfully with Linux on older/slower machines in the past. The RPI should have no problem spec-wise to run this with PD using only alsa ...
