======
|
||||
## Pulseaudio in Docker
|
||||
|
||||
Run it
|
||||
|
||||
```
|
||||
docker run --name pulseaudio --rm -ti --device /dev/snd andrey01/pulseaudio
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
Enter the namespace of a running container
|
||||
|
||||
```
|
||||
sudo nsenter -a -t $(docker inspect -f '{{ .State.Pid }}' pulseaudio)
|
||||
```
|
||||
|
||||
## Client setup for zeroconfig auto discovery
|
||||
|
||||
If you want the pulseaudio to automatically discover the published sinks,
|
||||
make sure ``/etc/pulse/default.pa`` has the following line:
|
||||
|
||||
```
|
||||
load-module module-zeroconf-discover
|
||||
```
|
||||
|
||||
Then restart pulseaudio:
|
||||
|
||||
Launching pulseaudio
|
||||
```
|
||||
echo "autospawn = no" > ~/.config/pulse/client.conf
|
||||
pulseaudio --kill
|
||||
rm -rf ~/.config/pulse/
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
If you wish your host system to use your docker pulseaudio server, e.g.
|
||||
accepting Fn volume Up/Down and On/Off keys, issue the following command
|
||||
```
|
||||
xprop -root -f PULSE_SERVER 8s -set PULSE_SERVER "tcp:localhost:4713"
|
||||
```
|
||||
|
||||
To remove pulseaudio properties from environment variables
|
||||
```
|
||||
pax11publish -e
|
||||
```
|
||||
|
||||
To test whether pulseaudio is working
|
||||
```
|
||||
PULSE_SERVER="tcp:localhost:4713" pactl list
|
||||
PULSE_SERVER="tcp:localhost:4713" alsamixer
|
||||
PULSE_SERVER="tcp:localhost:4713" mplayer some.avi
|
||||
```
|
||||
|
||||
To see what is being used by pulseaudio
|
||||
```
|
||||
$ netstat -lp |grep -i pulseaudio
|
||||
unix 2 [ ACC ] STREAM LISTENING 29632 2147/pulseaudio /tmp/.esd-1000/socket
|
||||
unix 2 [ ACC ] STREAM LISTENING 29635 2147/pulseaudio /run/user/1000/pulse/native
|
||||
```
|
||||
|
||||
If you wish to disable annoying "popping" notification sounds
|
||||
```
|
||||
gsettings set org.gnome.desktop.sound event-sounds false
|
||||
```
