PulseAudio became the standard audio system in Fedora 8, but it is a buggy piece of crap that crashes from time to time for no apparent reason. Or, sometimes it works great without any problems. Maybe it's not so bad.

Want to install PulseAudio mixer on Debian?

apt-get install pavucontrol

PulseAudio does not get along well with KDE

esdcompat: esdcompat is a compatiblity script that takes the same arguments as the ESD sound daemon esd(1), but uses them to start a the PulseAudio sound server with the appropriate parameters

PULSEAUDIO: Unable to connect: Connection refused

Playing WAVE '/usr/share/system-config-soundcard/sound-sample.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
*** PULSEAUDIO: Unable to connect: Connection refused

aplay -L
amixer
cat /proc/asound/version
cat /etc/asound.conf
lspci -v |grep -iC 10 audio
lsmod |grep snd

Try this: (THIS WORKED) A viable work around to get rid of pulseaudio piece o crap

rename pulse-default.conf in /etc/alsa to somethin else. (This file makes pulseaudio the default device for sound for alsa) run /sbin/alsactl restore

cd /etc/alsa
mv pulse-default.conf pulse-default.SUCKS
/sbin/alsactl restore
mplayer /usr/share/sounds/what_the_hell.mp3

Some people say remove the rpm

alsa-plugins-pulseaudio

and another Fedora 8 person has urged me to install

kde-settings-pulse

$ xmms *

• • • PULSEAUDIO: Unable to connect: Connection refused

$ mplayer * ....

• • • PULSEAUDIO: Unable to connect: Connection refused

[AO_ALSA] Playback open error: Connection refused Could not open/initialize audio device -> no sound. Audio: no sound Video: no video ....

The solution isn't as simple as starting pulseaudio, though:

$ pulseaudio
