Detect TV or Line-In sources

[jjlawren]

Detects TV or Line-In sources on devices that support those features. Displays appropriate icons on the display in those cases.

I was able to test with a Beam but I had to make some guesses on how it would work on an Amp, Connect, Five, or Play:5. Would appreciate if anyone with access to those could give a quick sanity check.

if sonos_settings.demaster and self.type not in ["line_in", "TV"]: ("go_sonos_highres.py" line 89 of 213 )

I had to switch "self.type" with "sonos_data.type" to make it work (?!) anyway.. it works!! 👍
Just one thing about "show_details": when i switched to line-in, it still displayed infos about the previous track

Oops, typo. Thanks for testing! I'll try to find time to fix both of those later today.

@v1nc3lx pushed an update, can you give a test? Didn't have a lot of time to test but this seems like a straightforward change.

looks good on Sonos Arc!

Five here!

switching to line-in -> wait -> screen turns off -> wait -> start radio: screen turns on with line-in picture and after a couple of seconds it switches to radio picture

I'm not totally clear on the timing in that sequence of events. It might be a limitation of the Sonos API if there's a slight delay.
