Howdy everyone,<br><br>Anyone had luck with a Roland/Edirol UA-25 with PD on a RaspberryPi? I've gotten it working fine with output, but enabling input gives me crackles and bad cpu usage. 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 ...<br>
