[pulseaudio-discuss] Help in setting up PA

Thanks for the response.

Currently, I'd like to use PA as a replacement for esound... to
basically send audio from different programs and from my audio capture
card to my audio playback card (capture and playback are on the same
card), taking advantage of mixing and syncing features of PA.   Sending
sound packets out to the network is interesting and I'd like to try that

Here's the uncommented part of my /etc/pulse/default.pa file:

#!/usr/bin/pulseaudio -nF

.ifexists /usr/lib/pulse-0.9/modules/module-hal-detect.so
load-module module-hal-detect
load-module module-detect

add-autoload-sink output module-alsa-sink device=hw:0 sink_name=output
add-autoload-source input module-alsa-source device=hw:0 source_name=input

.ifexists /usr/lib/pulse-0.9/modules/module-esound-protocol-unix.so
load-module module-esound-protocol-unix

load-module module-volume-restore

load-module module-rescue-streams


### Load something to the sample cache
load-sample x11-bell /usr/share/sounds/gtk-events/activate.wav

### Load X11 bell module
load-module module-x11-bell sample=x11-bell

### Publish connection data in the X11 root window
load-module module-x11-publish

load-module module-gconf
