Comment 149 for bug 178442

In comment 145 I reported that the problem had mysterious gotten fixed without me doing anything after a regular update. Now just as mysteriously, it has stopped working again. Desired behaviour: pulseaudio works on boot, jack works when loaded. Actual current behavior: PA does not work, though meters in PA manager show activity when a file is played using a PA app, mplayer, or aplay. Envy mixer app shows no activity. Once I have tried to play something this way, jack will no longer work, though if I start jack on boot, jack enabled apps (audacious, audacity, etc) playback fine. if I turn jack off and try a pulseaudio app, I get the previous behavior, and jack then no longer works. It starts, but no sound comes out, or else starting the jack server results in a hardware busy signal and failure to start. reboot, repeat.
