On Ubuntu Studio 9.04 (32Bit) on an Intel 2x2GHz machine I'm having similar problems (lots of xruns, audacity not coming up), if I start jackd in realtime mode. (As a side note: pulseaudio with module-jack also can't use jack, if jackd is started with the "--realtime" parameter.)
If I start jack like this... jackd -Z -P89 -dalsa -n4 (nozombies, priority:89, periods:4) ..then Audacity will start and successfully playback through jack. My parameters don't mean much to this issue here, except that I'm using "-P89" instead of "--realtime". Another program that I use (Renoise) can connect and playback through jack, even if jackd is started with "--realtime". -- Audacity crashes at startup when jack is running https://bugs.launchpad.net/bugs/159671 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
