Lost all sound in Xubuntu 14.04

Question

The other day, all sound in my Xubuntu 14.04 installation suddenly stopped working. I first tried this:

rm -r ~/.config/pulse
pulseaudio --kill

Which was suggested here, but it didn't do the trick. I finally got my sound working again after following this guide, using these commands:

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

Reboot and

sudo alsa force-reload

This worked for a while but then the sound disappeared again and trying the above steps again doesn't work. Does anyone have any ideas for what I can try to fix this? When looking in

pavucontrol

All I can see is the HDMI output on my GPU, my onboard sound isn't even listed.

Solution

I solved this on a minimal xubu desktop by doing this: install 'qasmixer' then go into the menu and choose 'Settings > Sessions and Startup > Application Autostart > Add' and name it whatever (ie Volume Control) then for the command type in: qasmixer --tray then reboot.
