Now in terms of the speaker icon, I believe it is the same as the yellow check (Technically satisfies the spec, but is a bit quiet) but am not sure on that (More of a guess). Maybe someone else can jump in on that topic.
Should clarify, while the table on that page isn’t necessarily what the readouts are, it is a pretty good place to start to understand what is being looked for.
For the specific details you would probably need to go to each platform and see what their targets are for submitted files.
