Help: No Sound Ubuntu Studio 18.04.2


#1

Hello, I'm hoping someone can point me in the right direction. When I launch pavucontrol I get some parsing errors but it launches - when I look at the output devices I have only have device listed: "Dummy Output"

I can confirm that I have an onboard HD audio controller and it's enabled in the BIOS. Can anyone help me troubleshoot this issue ? Thank you in advance !
