I offered 3 potential solutions that work across ever model (unlisted) and you guys are downvoting?

• USB - apple 30 pin: note that the pin number might change depending on release year. Someone smarter than me will mention why firmware might not work out.
• USB to aux: this will give you a headphone jack and is the most reliable
• FM transmitter: if you lack a headphone jack you can also get an FM transmitter. It makes your device a mini radio station. These are pretty unreliable or staticy, but sometimes you need an option. I would recommend a new player first.

Atm Xbox is my most reliable media player. PlayStation isn’t quite there, but would be a nice to have. My parents aren’t very tech literate and they use their smart TV/cable box. I have a friend with an older Roku/smart stick that’s incompatible. Have they added an app for Apple TV yet?

I need client side apps and easily sharing libraries with remote friends. Both are pretty hard to give up and not quite there yet.
