Here's my problem :

I just have installed QJackCtl on my Ubuntu 12.04 and when I start Jack I got this issue :

12:01:22.769 /usr/local/bin/jackd -dalsa -dhw:0 -r44100 -p1024 -n3 -i1 -o2
Cannot connect to server socket err = Aucun fichier ou dossier de ce type
Cannot connect to server socket
jack server is not running or cannot be started
Unknown driver "alsa"

If anyone knows the solution It would help me a lot !

My guess is you don't have the alsa-devel package installed, so when you compiled jackdmp it couldn't link to alsa.

Install that and recompile and I'm sure it'll work
