a52 plugin?
 

How do you setup the a52 plugin in your distro?

Have you seen this?

I figured it out:

asound.conf:
# Default to PulseAudio

pcm.!default {
type pulse
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
}
}

ctl.!default {
type pulse
}
sudo cp asound.conf /etc

copy daemon.conf and default.pa to .config/pulse/
edit default.pa #load-module module-suspend-on-idle
edit daemon.conf enable-lfe-remixing = yes
default-sample-rate = 48000

add .asoundrc to your home directory it's contents:
pcm.a52 {
@args [CARD]
@args.CARD {
type string
}
type rate
slave {
pcm {
type a52
bitrate 448
channels 6
card $CARD
}
rate 48000 #required somehow, otherwise nothing happens in PulseAudio
}
}
Delete /etc/alsa/conf.d/The a52plugin shortcut, if you don't it just won't work right. Don't worry alsaplugins automatically already installs the a52plugin.

Now either sudo alsactl restore and pulseaudio --kill or just reboot.

Forgot to put to go inside pavucontrol and pick Digital Surround 5.1 (IEC958/AC3) Output
