### Load something into the sample cache

#load-sample-lazy x11-bell /usr/share/sounds/gtk-events/activate.wav

#load-sample-lazy pulse-hotplug /usr/share/sounds/linuxmint-login.wav

#load-sample-lazy pulse-coldplug /usr/share/sounds/linuxmint-login.wav

#load-sample-lazy pulse-access /usr/share/sounds/generic.wav

### Automatically restore the volume of streams and devices

load-module module-device-restore

load-module module-stream-restore

load-module module-card-restore



### Automatically augment property information from .desktop files

### stored in /usr/share/application

load-module module-augment-properties



### Load audio drivers statically

### (it's probably better to not load these drivers manually, but instead

### use module-udev-detect -- see below -- for doing this automatically)

#load-module module-alsa-sink

#load-module module-alsa-source device=hw:1,0

#load-module module-oss device="/dev/dsp" sink_name=output source_name=input

#load-module module-oss-mmap device="/dev/dsp" sink_name=output source_name=input

#load-module module-null-sink

#load-module module-pipe-sink



### Automatically load driver modules depending on the hardware available

.ifexists module-udev-detect.so

load-module module-udev-detect use_ucm=0

.else

### Use the static hardware detection module (for systems that lack udev support)

load-module module-detect

.endif



### Automatically connect sink and source if JACK server is present

.ifexists module-jackdbus-detect.so

.nofail

load-module module-jackdbus-detect channels=2

.fail

.endif



### Automatically load driver modules for Bluetooth hardware

.ifexists module-bluetooth-policy.so

load-module module-bluetooth-policy

.endif



.ifexists module-bluetooth-discover.so

load-module module-bluetooth-discover

.endif



### Load several protocols

.ifexists module-esound-protocol-unix.so

load-module module-esound-protocol-unix

.endif

load-module module-native-protocol-unix



### Network access (may be configured with paprefs, so leave this commented

### here if you plan to use paprefs)

#load-module module-esound-protocol-tcp

#load-module module-native-protocol-tcp

#load-module module-zeroconf-publish



### Load the RTP receiver module (also configured via paprefs, see above)

#load-module module-rtp-recv



### Load the RTP sender module (also configured via paprefs, see above)

#load-module module-null-sink sink_name=rtp format=s16be channels=2 rate=44100 sink_properties="device.description='RTP Multicast Sink'"

#load-module module-rtp-send source=rtp.monitor



### Load additional modules from GConf settings. This can be configured with the paprefs tool.

### Please keep in mind that the modules configured by paprefs might conflict with manually

### loaded modules.

.ifexists module-gconf.so

.nofail

load-module module-gconf

.fail

.endif



### Automatically restore the default sink/source when changed by the user

### during runtime

### NOTE: This should be loaded as early as possible so that subsequent modules

### that look up the default sink/source get the right value

load-module module-default-device-restore



### Automatically move streams to the default sink if the sink they are

### connected to dies, similar for sources

load-module module-rescue-streams



### Make sure we always have a sink around, even if it is a null sink.

load-module module-always-sink



### Honour intended role device property

load-module module-intended-roles



### Automatically suspend sinks/sources that become idle for too long

load-module module-suspend-on-idle



### If autoexit on idle is enabled we want to make sure we only quit

### when no local session needs us anymore.

.ifexists module-console-kit.so

load-module module-console-kit

.endif

.ifexists module-systemd-login.so

load-module module-systemd-login

.endif



### Enable positioned event sounds

load-module module-position-event-sounds



### Cork music/video streams when a phone stream is active

#load-module module-role-cork



### Modules to allow autoloading of filters (such as echo cancellation)

### on demand. module-filter-heuristics tries to determine what filters

### make sense, and module-filter-apply does the heavy-lifting of

### loading modules and rerouting streams.

load-module module-filter-heuristics

load-module module-filter-apply



### Load DBus protocol

#.ifexists module-dbus-protocol.so

#load-module module-dbus-protocol

#.endif



# X11 modules should not be started from default.pa so that one daemon

# can be shared by multiple sessions.



### Load X11 bell module

#load-module module-x11-bell sample=bell-windowing-system



### Register ourselves in the X11 session manager

#load-module module-x11-xsmp



### Publish connection data in the X11 root window

#.ifexists module-x11-publish.so

#.nofail

#load-module module-x11-publish

#.fail

#.endif



load-module module-switch-on-port-available



### Make some devices default

#set-default-sink output

#set-default-source input
