Another thing to consider trying is to change the "Interface" setting from "default" to "hw:0," or whichever one looks like it corresponds to your soundcard (to see names, click the little " > " button to the right of the interface setting in qjackctl). Sometimes the linux installer has a funny idea of which device should be the default sound interface; sometimes it will find two or three things on your system you wouldn't consider an audio device -- I've even had it choose a dialup modem as the default audio device. You can configure hw:* device order in /etc/modprobe.conf.
