I did find two files that I tried deleting:
~/.qt/.qjackctlrc.lock
/var/lock/subsys/alsasound

Initialy I was getting the same error, but after rebooting now it works!
Thanks!

Well, I shouldn't say it's now working... now I'm getting:
   required capabilities not available
   capabilities: = cap_ipc_lock,cap_sys_nice,cap_sys_resource+e
within the qjackctl messages on start.
But, I guess this is unrelated, so I'll have to look into this now...

thanks again.
