No Audio on Ubuntu 16.04












0















currently experiencing the issue of having zero sound. I know for a fact that sound once worked on a previous install of Ubuntu, but now I am totally at a loss as to what has happened. I believe I was tampering with some bluetooth settings so that my bluetooth headphones would work, this was awhile ago so I can't remember much details but I don't believe I went too far into it, I suspect maybe this is how I might've broken it though.



Couple things that I've noticed trying to troubleshoot: pavucontrol cannot be ran as su, only without it. Pavucontrol doesn't list my soundcard.

My soundcard: Realtek ALC255



Here is what kind of errors I get doing various things:



Running pavucontrol as su.

Which started the service but did not fix the issue.



Here's a rundown of things I've attempted:




  • Reinstalled pulseaudio/alsamixer/pavucontrol.

  • Restarted pulseaudio.

  • Gave user permissions to the home directory.

  • Got access to the audio group in group permissions.

  • Apt update and apt upgrade.


Any help or direction would be greatly appericated.
