    PulseAudio Setup

Notes on my pulseaudio installation. PA was acting screwy in 14.04, after

upgrading to 16.04, it appeared fixed, but had issues w/ my video driver. After screwing with the nvidia driver, audio was completely broken.  This is a general troubleshooting guide.
Audio Setup

I use front and back outputs, which must be combined.
As usual, try restarting pulseaudio and alsa
'''
pulseaudio --kill
pulseaudio --start
sudo alsa force-reload
'''
Reinstall Pulseaudio and ALSA

'''
sudo apt-get purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
'''
Enable combined output in /etc/pulse/default.pa

'''
load-module module-combine-sink sink_name=combined
set-default-sink combined
'''
Useful commands

'''
pulseaudio --dump-modules
pulseaudio --dump-conf
paman
pacmd list-sinks
paprefs
aplay -l
'''
Pulseaudio equalizer

Package must be installed from wepupd8 ppa
'''
sudo add-apt-repository ppa:nilarimogard/webupd8;
sudo apt-get update;
sudo apt-get install pulseaudio-equalizer
'''
