No sound with 20.04 installed on 2011 iMac hardware

Asked by Jim Viscusi

Unable to get any sound from either built in speakers or headphone jack since first install. Currently running latest patches.

I'm following this guide to debug and have completed steps 1 and 2. I ran this command:

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

and the output is here

Grateful for any assistance

Do you get sound in headphones? If you install and use pavucontrol does it help?

Can you help with this problem?
