I think my comment may get buried but I'll try anyway :)

I'm one of the engineers working on web.dev and recently we had some issues with the way the report was being generated (detail here: https://medium.com/dev-channel/web-dev-status-update-14th-no...)

Specifically, there were audits flagged as "not applicable" and the alpha version of Lighthouse was instead flagging them as failures. That's why it looked like it was telling you to add audio or images—it was actually saying those audits are not applicable because your site doesn't use audio or images. I think that bug has been fixed in Lighthouse but feel free to reply to this comment if you're still seeing it.

We've also temporarily turned off the PWA audits—they were having some bugs of their own based on the infrastructure they were running on. Based on the feedback in this thread we'll look into making them configurable so folks can choose if they want to run them.

We'll also be opening up the repo shortly so folks can file bugs there directly.
