(Sorry for the title, but I'm pretty ignorant when it comes to home entertainment equipment)
Recently, I got a 48" TCL Roku TV to replace a 59" Sony projector TV. It's pretty nice, with a good image after some fiddling and with the flexibility of the Roku software, but it has a problem; the sound leaves a lot to be desired.
Because of that, I'm thinking of saving up to get an external sound system. I figure I might as well go all-out and get some sort of 5.1 or 7.1 surround sound system.
Since the TV only has a 3.5mm audio jack and an optical audio out, running one of those to a surround system would be out of the question, especially since at least the 3.5mm Jack outputs terrible quality sound.
I believe a some sort of A/V receiver would be the best option. It would need to have 3 HDMI inputs (at least), possibly a few composite inputs, and optical audio in so that the smart features of the TV could have sound run to the system.
The problem I have is a complete lack of knowledge on how to look for what I need. Do receivers have the capability of acting as a sort of switcher for the inputs, just needing one cable to the TV? Do they work as passthroughs?
I have no idea how to look for one, and I don't know if this is even the right place to ask (or if I asked correctly), but I'm more than willing to completely rewrite the question if that helps anyone help me.
