PulseAudio – A great sound server

PulseAudio is a sound server for POSIX and Win32 systems. A sound server is basically a proxy for your sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count and mixing several sounds into one are easily achieved using a sound server.”

    I come back to esd because my firefox chashes with libflashsupport-pulse :-(, does anybody has the same problem?

  2. gianvito says :

    I haven’t that problem… after installing libflashsupport-pulse (that is on my repository too) my firefox hadn’t no more crashes…

  3. Henrique C. Alves says :

    I guess I fail to understand what _exactly_ PulseAudio is. I know that it isn’t an ALSA replacement, neither a Xine/Gstreamer replacement. Is it a replacement for things like Esd, Artsd? Also, does anyone know if it clashes with KDE upcoming Phonon?

  4. gianvito says :

    yes… you’ve got it… however the only way to know if it crashes is to try… even if kde4 is still a “beta”… 2 times on 3 it crashes…

    I’ve avahi-daemon[6241]: cap_set_proc() failed: Operation not permitted issue.

    Avahi-daemon is after hal which, afaik, automatically starts dbus.

    Otoh, 2.6.24 kernel has no capability module which was required to solve the above issue. Any hint?

    my deamons line is:

    DAEMONS=(@syslog-ng @network @netfs @crond @postgresql preload portmap fam dbus avahi-daemon hal gdm alsa pulseaudio)

    try to emulate that… with this tips i’ve resolved my problem… Putting avahi-daemon after dbus and then hal (restart after that)

    PS. I’ve also rebuilt my zen kernel with “Security Options —-> Enable different security models —-> Default Linux capabilities” and “Socket and networking security hooks” that is in the same option… both enabled

    Let me see if it works

  7. Gour says :


    The trick was to rebuild the (zen) kernel with those Security options ;)

    Thank you for the help.


  8. gianvito says :

    np :)

  9. mike says :

    Rebuilding the Kernel sucks here.

    That must be easier with arch!!

  10. gianvito says :

    With the arch default kernel there is no need to rebuild…
