Hi,you can try
I've just installed qjackctl and am having trouble with the audio setup in a few programs (like pd, supercollider). When I run these programs I get no sound and also no error messages in qjackctl.
Is there a way to test whether jack is working correctly?
Here is my setup:
Ubuntu 13.04
qjackctl 0.3.10
libjack-jackd2-0
libjack-jackd2-dev
Any help would be greatly appreciated.
Thanks,
Peter
jack_metro -f 220 -A 0.6 -b 120
connect in qjackctl metro with system out, if jack is setup correct, you will hear the metronome.
(press ctrl+c to exit metro)
You can't. JACK doesn't have settings like this. There are ways to make connections "persistent" (i.e. recreated at startup) but the right solutions vary depending on the JACK clients you are using (and, for example, whether or not you use a session manager).
FWIW ... my builtin soundcard is similar: the default device has 8 channels and the rear connectors are actually channels 7 & 8. Really this needs fixing inside the h/w mixer of the audio chipset, but I'm not sure if ALSA has the capability to do this at this point in time. I believe that Windows drivers can.
