> 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.
