You can get A/V switches with remote controls. The one i have takes rca, pcbr and hdmi and they all operate independently so you have 12 different inputs! I just programmed it into my universal remote and use a soundbar.
Hdmi splitter puts HDMI audio to OPTICAL, rca hooks to a 3.5mm cable that hooks into the ANALOGUE on the soundbar.
For older tv tuner stuff (Atari 2600) i run it through my VCR
