Ok, though I know nothing about this particular package set, the question raises itself that, why should a JACK-connective application be using OSS (or ALSA) for audio output, when it can ensure, through JACK, that platform-agnostic output is available? -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

So, if the problem is Jack hogging /dev/dsp, and if /dev/dsp1 is not being hogged but it's output isn't getting through, is there a way I can route /dev/dsp1's output to Jack's input so that it all goes out /dev/dsp? You wouldn't want to do this anyway, because latency would be horrible. The pipeline would go something like: Gtick - aoss - OSS-JACK router thingy (which doesn't exist) - JACK - ALSA I hate ALSA and dmix: dmix is a userspace library plug-in, and not at kernel level, so not only do some apps not conform to it (they don't /have/ to link against that library), it has latency problems too. I welcome the day when the newly open-sourced OSS4, and its lovely kernel-level vmix virtual mixer, replace ALSA and dmix forever. OSS is a much nicer sound system anyway, even if it did betray us by closing up last decade. My suggestion is to give up on Gtick if you're intent on using JACK. If you're into overkill, you could have Hydrogen give you a beat to the right BPM, but I'm sure there are other applications that I haven't heard of that are more suitable. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
OSS apps vs. ALSA apps
I finally discovered why I couldn't run Creox and practice guitar using Gtick for a metronome: Gtick is for OSS, and it throws up the error Couldn't start metronome. Please check if specified sound device and sample file are accessible if I try to start it clicking after opening starting Jack. Naturally, Jack won't start if Gtick is already running. It looks like installing the alsa-oss package is what to do to make Gtick compatible with ALSA and therefore with Jack, but I hesitated and thought I'd ask here whether there's any reason not to install that package in an Ubuntu Studio environment--not sure whether it could interfere with something I'm not aware/thinking of. Am I safe on the right track? (If there isn't any reason not to install alsa-oss, then should come installed automatically by Ubuntu Studio so that Gtick plays nice with all the Jack applications out of the box?) --Ray -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
