@classicalpiano , If you wanna just make do with your existing components, i.e., you don’t want to get a dedicated multichannel/atmos processor, additional speakers, etc, do as follows:
a) Get a Apple TV latest gen box/Nvidia Shield/Google Chromecast/Amazon firestick/etc, i.e. whatever your choice of streaming device is and plug its HDMI output directly into a HDMI input of your AWOL projector.
b) Run the projector’s SPDIF output into a SPDIF input of your hifi stereo dac/preamp for audio...
With your 2 speakers, you will now have hifi stereo through your hifi DAC, amps, etc for whatever you are watching! Hope that helps..
