I can hear crickets chirping in the Multimedia Production forum... might as well try here instead...
I installed LMMS 0.4.5 on my computer (Ubuntu 9.10), but I'm getting no sound output from the program on ALSA, and whenever I try one of the other options (PulseAudio, OSS, etc.) it reverts to dummy audio. I tried installing JACK to correct the problem, but JACK seems to be giving errors and quitting, and in the past I've always used ALSA for LMMS and it's worked just fine.
The problem is local to LMMS, even after a reinstall. My audio output is fine for all other programs I've tested the problem for so far.
What could be causing this issue?
Also, I just noticed that my instances of LMMS are not being terminated after the windows are being closed...
