Bug#569284: kmix: Fail to work on LTSP thin clients using PulseAudio

[Petter Reinholdtsen <pere@hungry.com>]

retitle 569284 kmix: Fail to work on LTSP thin clients (provides ALSA->PulseAudio, PuseAudio and ESD)
thanks

Sune put me in contact with Colin Guthrie, who is working on a kmix
patch for pulseaudio.  Sune provided me with a kdemultimedia test
package with such patch included, and I tested running it via a thin
client, and it caused kmix to segfault.  The thin client have ESD,
ALSA via pulseaudio and pulseaudio enabled.  I've forgotten the URL to
Sunes test packages, but have asked him to submit the URL to BTS.

When running the same kmix version locally on the server, where ESD is
not enabled and the alsa devices are local, kmix only showed a dummy
output control instead of the local audio device.

I lack contact with the test setup right now, so I can't test any
more.  Colin asked for this input:

  1. Get a backtrace for the crash - preferably with an updated patch
     from the above if it fits.
  2. On the dummy machine, try and get some info as to what is hogging
     the device nodes or if check if there is a permissions problem on
     the sound devices themselves.

Details about 2) can be found on <URL: http://pulseaudio.org/wiki/KDE >
(basically lsof/fuser/getfacl results).

The latest version of the pulseaudio patch is available using this
recipe:

  git clone git://colin.guthr.ie/kdemultimedia
  cd kdemultimedia;
  git checkout -t origin/pulse-4.4.4
  git diff master..pulse-4.4.4 > mypatch.patch

Colin said it *should* apply cleanly on top of 4.4 branch of KDE and
hopefully the 4.4.4 source tarball.

Happy hacking,
