I just did an in-place fc6-to-f8 upgrade and it went pretty smoothly. One gotcha was I had to adjust the qjackd settings thusly: 1. Change "Server Path" on qjackctl's Setup page to "pasuspender jackd --". This suspends PulseAudio so it isn't hogging the ALSA ports while I'm running jackd. 2. Change the "Interface" setting to "hw:0" from "default". jackd wouldn't start up otherwise. Any idea why? AG
