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.
