I use qsynth to output sound from my MIDI keyboard. That part works great, and the MIDI keyboard sounds great.
However, once that MIDI keyboard is connected, my computer immediately becomes unable to output ANY sounds other than sounds from the MIDI keyboard, and this continues until I reboot the computer, even if I stop and close both qsynth and qjackctl.
I have no idea what's causing this, but I find it really annoying. How can I stop it from happening?
My Ubuntu version is 13.04 (Raring) and I have qsynth 0.3.6 and qjackctl 0.3.9. My system uses pulseaudio 1:3.0-0ubuntu6 to output sound, which I've heard has some problems but I'm not sure if this is one of them.
alsamixer
?qjackctl
could be a possibility as well.
