Make sure you stop jack first:
Code: Select all
killall jackd lashd ladishd a2jmidid a2j
killall -KILL jackdbus pulseaudio
jackdbus and pulseaudio must be killed with the "-KILL" switch, or they will never stop.
Thanks again, I'll try it. At present, I have a more pressing problem: I have no sound at all. I've been looking everywhere to see if I had something muted or turned down, but in Alsamixer (or Kmix for that matter) everything looks ok.
There's something else, BTW: I can't see any capture options in Alsamixer and Kmix. I can see from screendumps at various sites that most people have these options, but I haven't got them for my sound card. I _do_ have these options for my TV tuner card that's installed in the same computer, but that doesn't help much. Is there a way to select which of the cards should be used for sound capture ? (and then, after choosing the sound card rather than the TV tuner card, the capture source options might appear).
A third thing now I'm at it: I get an error message when trying to install the automatic updates and bugfixes (pasted in below). I'm hesitant to try to solve my no sound problem as long as it might be taken care of by an update. Is it likely that an update would solve the problem?
