FYI when I set up qjackctl to use the RC-505 instead of the Scarlett, I see
that jack is set up as follows:
/usr/bin/jackd -dalsa -r48000 -p256 -n2 -Xseq -D -Chw:RC505 -Phw:PCH
I have no experience with the RC-505 but I wonder whether it supports a
sample rate of 48 kHz. If it can't then the above jackd command will fail
because the RC-505 will reject the request to operate at 48 kHz.
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.
