You could try replacing the sleep 5 with: while test ! -e /var/lib/jack/tmp/jack-$UID; do sleep 1; done You will need to change the /var/lib/... path to whatever your jackd uses, but it works for me with a Planet CCRMA jackd. It just waits until jackd has created the FIFO that it uses to communicate, hopefully by which time clients should be able to connect OK. "man test" for details. - Steve
