I bought an android tv recently and the sound on 5.1 sources (hotstar, plex, netflix) is terrible. Too loud music and very quiet dialogues. I am not looking for a 5.1 setup. What I seem to need is an AV receiver which can downmix to 2 channels properly while increasing the center channel. All AV receivers I have seen are > ₹25k. An alternative is to get a soundbar. But, I already own a good 2.1 setup (Logitech Z-2300 's subwoofer/amp and wharfedale 10.2 diamond speakers). So, buying a soundbar seems to be redundant). So, what is the cheapest way to get good sound?
