Bounty: 100

This is a fresh install of 20.04 on a Dell Inspiron 3000.

The system will detect an external headset and hdmi as an output/input, however, it will not detect the internal speakers/mic.

Kernal – 5.12.10-051210-generic

Sound driver – Advanced Linux Sound Architecture Driver Version k5.12.10-051210-generic.

Running alsamixer shows two options of 0 HD-Audio Generic and 1 HD-Audio Generic, but none of these seem to do anything.

Any ideas on where to look next would be greatly appreciated, thanks.
