I have the same sound chip as yourself. I can't seem to get jack
to start. I have not goteen as far as yourself but I will be there
shortly configuring midi. Can you please send me your start command for jack. this is
what I'm using and I'm getting xrum values od 6.0 msec
jackd -d alsa -d hw:0 -r 44100 -H -p64
Good luck
