Hej,
I have a problem with connecting to a running jackd, clients are not
able to connect. They are definitly not running as another user as
jackd itself.
I even tried (only for testing) to run qjackctl as root, with no success
either.
I can start jackd by a shell and by qjackctl, but after starting no
client is able to connect. Even giving the jackd-instance a name by the
-n option, clients are not able to connect while specifying that name.
There are also no other clients running that could have the same
client-id as my test-clients (qjackctl itself, meterbridge, adour2).
OS: Ubuntu 6.10 (Edgy), Kernel 2.6.17-10-386
Hardware: M-Audio Delta 44
jackd: 0.102.20
qjackctl: 0.2.20
I had no problems with jackd before upgrading ubuntu from 6.06 to 6.10.
Adour points to a problem with ulimit and locked memory while starting, so
I give the contents of limits.conf, too (this is not the cause
for my troubles, I believe):
mechko@almeida:~$ cat /etc/security/limits.conf | grep -v "#"
@audio - rtprio 99
@audio - memlock 250000
@audio - nice -10
The message-window after pressing the Start-Button in qjackctl (verbose
mode on). There should be an error-message that gives a reason why
clients are not able to connect, but I can find none.

Could you please give me a hint what to do? Thanks in advance,
