You must hook it up using qjc to get sound. (Or > possibly at the command line.) Downloaded qjackconnect, ran it, hooked some things up and now zynaddsubfx works with jack. (btw, zynaddsubfx absolutely rocks!) Everything seems to be cooperating fine, except for the fact I get massive amounts of xruns when sequencing with rosegarden. What is odd is that the load goes up incrementally over time, roughly about 30 seconds and its xrun city. I looked at jackd options, maybe someone could explain what they do for me: 1. -p,--period <n> frames per period (default: 1024) 2. -n,--nperiods <n> number of periods in hardware buffer (default: 2) 3. -H,--hwmon use hardware monitoring, if available (default: no) 4. -s,--softmode soft-mode, no xrun handling (default: off) Also, qjackconnect constantly segfaults. Is this common? Another issue I ran into was my alsa drivers. When trying to use the rc7 and rc8, some software runs into an ioctl() problem (iiwusynth in particular). It looks like when it opens my /dev/snd/pcmC0D0p device, that it passes a bad argument to ioctl(), then just sits in a tight loop until I ctrl-c it. The problem appears to be in alsa-lib. I reverted back to rc5 and the problem went away. Has anyone tried the dmix plugin thats part of alsa rc8? This looks interesting, but im scared if I install rc8, I will be bitten by that alsa-lib bug again. -- Levi Burton http://www.puresimplicity.net/~ldb/
