Thanks to your information, I was able to make my Soundblaster Live emu10k1, the Java Sound (Gervill) synthesizer, and Qsynth all co-exist nicely using JACK (QjackCtl). Also, I now don't have to have my music player set properly to use JACK, or to use PulseAudio - it plays with either one. I also have probably eliminated the hangs (time will tell). The thing that made the difference was that in the mixer (pavucontrol in the case of Lubuntu), I had to set the PulseAudio JACK Sink as the fallback (primary) sound card, rather than the Soundblaster Live. I didn't need to manually change any system configuration files to make this work (so far). The only thing that doesn't work together with JACK is the Flashplayer (for YouTube Videos). I have to terminate QjackCtl to play one of those and have sound. Thanks again for your helpful information. -- Sincerely, Aere ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
