jack_lsp is the exception that works.
The interesting part of
~: strace jalv.gtk http://gareus.org/oss/lv2/balance
is probably:
socket(PF_FILE, SOCK_STREAM, 0) = 9
getuid() = 1000
connect(9, {sa_family=AF_FILE, path="/dev/shm/jack_default_1000_0"},
110) = -1 ENOENT (No such file or directory)
The full thing for jack_simple_client:
