do you have a MIDI device controller that is plugged in? -- jack & rosegarden can't play sound realtime using midi device https://bugs.launchpad.net/bugs/571368 You received this bug notification because you are a member of Ubuntu Studio, which is a bug assignee.
Status in “jack” package in Ubuntu: New Bug description: Binary package hint: qjackctl Hello I installed linux-rt kernel & got jack working with the command: sudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf'. I can use the synth plugin in rosegarden, but using the general midi device won't play any sound, when editing the channels. I've installed timidity, qsynth, dssi stuff and everything I heard should be usueful, but no luck. I've been trying to get it working for several months now. I'm using ubuntu 9.10 (not studio) in rt kernel. I have an EeePC with Intel High Definitin Audio sound card & I don't use any extra hard-ware. I'm wondering if I have to install something else too, or I have to try some external soundacrd, or just run another command in terminal that will fix it, or change some setup in rosegarden... Please check my screenshots about the connections. It's a pity, that Ubuntu Studio stuff doesn't work out of the box... Any help appreciated, it's very important for my work! Thanks...
