No a receiver is not at all needed in a stereo setup. All you need is an HDMI extractor. Connect your hdmi sources to it. Output options are hdmi, optical and rca. Use the hdmi to connect to your tv/projector. Use the optical to connect to your stereo dac. Done. There is no lag at all between hdmi video and audio over optical to amp.
Above is my setup currently. Additionally I have a hdmi splitter which splits the hdmi to tv and projector. I am honestly enjoying the setup more than when i had a 5.1 setup. 2.1 for stereo, prime, Netflix, etc rocks.
