Does PulseAudio run on top of ALSA? Should I get rid of ALSA first? ALSA is a sound server, right? So is PulseAudio... As you can tell I'm somewhat confused. Anyway right now I seem to have both - except neither seems to error no such be working :-\ /etc/asound.conf contains: pcm.pulse { type pulse } ctl.pulse { type pulse } pulseaudio is indeed running. However, trying "amixer -Dpulse" results in ALSA lib control.c:874:(snd_ctl_open_conf) Cannot open shared library /usr/lib64/alsa-lib/libasound_module_ctl_pulse.so amixer: Mixer attach pulse error: No such file or directory` I checked and the file is indeed not there. I do however have /usr/lib32/alsa-lib/libasound_module_ctl_pulse.so Playing a song in VLC will make the stream show up in pavucontrol, but no audio will make its way to my speakers... I am in groups pulse and pulse-access (not entirely sure what they're for, but figured they can't hurt), and have followed the guide http://pulseaudio.org/wiki/PerfectSetup to the letter. Update: Oddly enough, when I delete /etc/asound.conf, audio streams still show up in pavucontrol... so... is pulseaudio actually running? Am I using it? How can I tell? alsa pulse-audio share|improve this question edited Dec 5 '11 at 15:36 Tom Wijsman 45.7k19143227 asked Jan 5 '10 at 5:56 Mala 2,11382330 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted Here's a straight answer: PulseAudio is a sound server; ALSA is a kernel sound subsystem. They do different things -- ALSA provides chipset drivers for your soundcard or onboard sound chip; PulseAudio routes sound between programs, sound chips, and even systems. PulseAudio is a sound server for POSIX systems. A sound serve
