I completely removed a pulseaudio mod I installed last year and also completely purged all the audio drivers.<br/><br/>I then installed aptitude based on some recommendations and used that to reinstall all the stock ubuntu audio drivers using --purge along with reinstall. Still after that I had no sound.<br/><br/>The key was running this command and rebooting:<br/><code>killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse*</code><br/><br/> I stole that code from the ubuntu help page at: <https://help.ubuntu.com/community/SoundTroubleshootingProcedure>.<br/><br/>If anyone else has problems hope this helps. I still cannot use the dedicated volume buttons on my keyboard. I'll work on that soon, at least my speakers work now.
