Sorry.
Perhaps try different explicit sample formats. Maybe the RC-505 only
accepts a single sample format which happens to differ from jackd's default.
The only other thing I can think of is the period size (-p) and number of
buffers (-n). In the past I recall that some devices operated better with
particular choices of these, although I'm not sure that this applies these
days. For example, I have a memory that some USB devices worked best with
"-n 3" but I don't have a reference off-hand - maybe this is my imagination
at work, or it's something which hasn't been relevant for many years.

A very quick scan of the internet didn't turn
up detailed information
about the RC-505. However, in the user manual I note on page 26 only
44.1 kHz WAV files are supported. It is therefore possible that the
unit operates at a fixed sampling rate of 44.1 kHz and therefore it
might be worth trying "-r44100" in your jackd command to see if that
works any better
Unfortunately changing the sample rate as you suggested didn't work. Any
other ideas?
