Basically the title but I have a few requirements I’d love to meet.

I have a “Smart Soundbar” that I actually quite like the audio of, as well as serving as an HDMI hub and switch, with a decent remote ect. Basically I like the hardware quite a bit and it is generally high quality, particularly the audio quality, it’s from a reputable home audio company, blah blah blah.

I got it as part of some promo with my ISP so it has their slightly customized version of Android TV on it. I’ve already gotten side loading apps working, I have my YouTube client and VPN running, Jellyfin, all that. Now I just want to get rid of all the google apps and ISP tweaks. I would also love to maintain some sort of casting option akin to chromecast or AirPlay. Is there an Android app that turns a device into an AirPlay receiver? I have one for Linux.

I realize the “best” option is to not connect the thing to the Internet, but that defeats the purpose of having access to say the Netflix app with my VPN running. Or giving relatives a “Netflix” like experience with my Jellyfin server running offsite.

Just looking for any advice on maintaining functionality of the high quality speaker and generally good Android TV interface while clawing back some privacy. I’d be willing to flash it with something totally different though if anyone know how to do that.
