Ubuntu 16.04 audio not working correctly. No hardware listed in audio settings and sound above 100% does not stay set. I have read another post telling me to delete the pulse folder from /home/.config/. This works for a few moments then the pulse folder is reinstalled. How do I delete this folder and have it not come back, or any other fix's. Thank you for any help with this issue.
This issue was related to firejail. I stopped running chrome in firejail and this issue was resolved. Running Google Chrome in firejail caused system sound hardware not to display in the sound settings, requiring a reboot.

Firejail's website describes a known problem with pulseaudio 7.0/8.0:
This fix worked for PulseAudio/Firejail problems I had on 16.04 that were similar to what you describe.
