We have had a Macbook Air (A1466) laying around for years after it became useless due to not getting any more updates so modern browsers wouldn't run, etc. etc.

Today I decided to dust it off and install Ubuntu - that all went great. No issues with wifi drivers or anything. The only issues I am having are that I have no audio input or output (only device available is "dummy output") and no webcam.

I'm not really sure where to start. I have used linux before, but it has been years (Ubuntu 11 or 12 was the latest I ever touched).

Any suggestions?

EDIT:

This is what I get from running lspci -V
