Since I want to use Tuxguitar (and Dosbox with Dungeon Keeper ^^) it seems that I have to get a running jackd.
But after a few googleable errors I'm stuck now...
21:09:30.449 JACK is starting...
21:09:30.450 /usr/bin/jackd -R -dalsa -dhw:0 -r48000 -p1024 -n3
21:09:30.452 JACK was started with PID=5228.

What do I have to do?
Besides I'm a little confused with all the alsa midi jack stuff so please tell me if I try to solve the issue in the wrong way.

I'm doing a lot of jack alsa experiments
you may find it starts via command line with like..
jackd -d alsa -d hw:0
I found this would work and not qjackctl
so... I found it's the periods line in your output that was the clue/fix for me
ALSA: got smaller periods 2 than 3 for playback
it's asking for the exact same number of periods
look at setup in qjackctl change periods/buffers to whatever... is it 2 or 3...
anyways... that's just one of my many fascinating struggles with JACK
definitely enjoying the climb though!
the biggest thing I gound was that of the two ways the jack home page says to install the second way worked and the first dev/shm/jack-0 alreasdy exists error was a thing of the past..
gotta add a line and compile a bit though as I recall.
sorry I don't have time to detail right now for anyone interested... crazed!!!
go to the jack home page and note the second way of installing...

I ALOS found that for example....firefox may sometimes still have a running process so I killl it via system noitor page... this gets aroud the HW:0 in use thing.... jack is great and I do plan to become a guru a bit with it ....
the whole alsa jack ....getting flash to play thru usb headphones thing..... very heady stuff... hehehe
really I've found what I'm going to try to sorta master over the next while... by making most all the mistakes of course... as the saying goes...
it's like fine art!
