Pulseaudio: Welche Komponente leitet ALSA-Clients um?

02/09/2013 - 06:37 von Holger Marzen | Report spam
Ich habe keine ~/.asoundrc und keine /etc/asound.conf.
Mein "Hauptsystem" zur Soundausgabe ist JACK, d.h. den starte ich
zuerst. Dann starte ich Pulseaudio. Die /etc/pulse/default.pa hàngt
unten an. Weil ich zum Skypen (mit Pulseaudio) das Mikrofon meiner
Webcam brauche, ist in Pulseaudio das Webcam-Mikrofon in der Zeile

load-module module-alsa-source device=hw:2,0

eingebunden. Das funktioniert auch prima.

Wenn ich nun ALSA-Clients starte, erfolgt die Ausgabe trotzdem über
Pulse, d.h. Pulse biegt ALSA um:

aplay -L

default
Playback/recording through the PulseAudio sound server
[...]

Welches Modul ist dafür zustàndig, dass diese Umleitung erfolgt. Ich
würde nàmlich ALSA-Clients lieber direkt zu JACK umleiten statt erst
über Pulseaudio und dann zu JACK zu routen. Ich hatte folgende
/etc/asound.conf, aber mit Start von Pulseaudio wird die wirkungslos:

pcm.!default {
type plug
slave.pcm "jack"
}

pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}

### 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-alsa-source device=hw:2,0
#load-module module-alsa-sink
#load-module module-jack-source
load-module module-jack-sink

#### Automatically load driver modules depending on the hardware available
#.ifexists module-udev-detect.so
#load-module module-udev-detect
#.else
#### Use the static hardware detection module (for systems that lack udev/hal 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
.fail
.endif

### Automatically load driver modules for Bluetooth hardware
#.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 rateD100 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

### Enable positioned event sounds
load-module module-position-event-sounds

### Cork music streams when a phone stream is active
#load-module module-cork-music-on-phone

### 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

Irgendwas in /usr/share/alsa/alsa.conf.d/.

Ich hatte folgende /etc/asound.conf, aber mit Start von Pulseaudio
wird die wirkungslos



Da scheint es Bugs zu geben: <http://bugs.funtoo.org/browse/FL-608>
