I have and old laptop with some good screen but awful audio. What i want is to stream the audio on my decent tablet to use it as a speaker. This is not a server cloud or anything similar, just a pc with some linux distro installed.
you need snapcast, the server on your laptop will out put over the network and the app on your phone will play it. also it would allow you to add more speakers over time
There’s this: https://github.com/mkckr0/audio-share
Or this: https://audiorelay.net/downloads
Probably 50 more apps for it as well. I’ve not tried it, but any of them should work, I imagine
Just FYI, I’ve seen and heard a speaker looking like a tin can, sitting on the desk, perform very solidly — and I myself was using Sennheiser headphones and pretty respectable boxy speakers by that time. This was ten years ago. By now any little standalone speaker can probably outperform one embedded in a tablet.
Regrettably I don’t know any model names, might have to look for them myself sometime.
You COULD use a casting client and server, but it’s probably much easier to just use the tablet as a Bluetooth target. Some phones/tablets just do this, but there’s also simple free apps out there that enable this as well.
