MPD (Music Player Daemon)

Shared pulseaudio daemon, separate sink

MPD allows access from any address and uses a password for security.

The config file is well explained.

Shared pulseaudio daemon, separate sink

Edit /etc/pulse/default.ca to enable a unix socket for sharing the pulse daemon, and set a default sink for other applications.

Listing 1: /etc/pulse/default.pa (excerpt)

load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.1.0/24
set-default-sink alsa_output.usb-SCEA_Inc._Logitech_USB_Headset-00.analog-stereo

Grab the full names of your sinks:

pactl list sinks|grep Name

Name: alsa_output.usb-SCEA_Inc._Logitech_USB_Headset-00.analog-stereo
Name: alsa_output.pci-0000_0e_00.3.analog-stereo
Name: alsa_output.pci-0000_0c_00.1.hdmi-stereo

See the pulse output section of mpd.conf for setting the sink.

Restart pulseaudio and mpd:

pulseaudio --kill
pulseaudio --start
systemctl restart mpd
