A quick guide on how to output audio from the projector via different interfaces – AWOL Vision

🚀 The following applies to the Aetherion Max & Pro:

1) Optical (S/PDIF&Toslink) Output:

Connect the projector to your external speaker or AVR using a TOSLINK (optical) cable
Go to Settings -> Display & Sound -> Audio Output, select Optical (S/PDIF)
Then go to Sound -> Digital Audio Output -> Digital Audio Format, and choose Dolby Digital

2) HDMI eARC/ARC Output:

Use an HDMI 2.1-certified cable to connect the projector’s HDMI 3 (eARC) port to your soundbar or AVR
If your audio device supports eARC, go to Settings -> Inputs -> HDMI Format, and set HDMI 3 to Enhanced, and enable the HDMI Control(CEC) feature.
If your device only supports ARC, set HDMI 3 to Standard
For HDMI cables over 5 meters, we recommend using a fiber-optic eARC HDMI cable for stable transmission
Go to Settings -> Display & Sound -> Audio Output, select HDMI (eARC)
Then go to Sound -> eARC, and set it to Auto or Off based on your device
Finally, in Sound -> Digital Audio Output, choose Passthrough

3) 3.5mm Headphone Jack:

Simply connect your external speaker to the projector via the headphone port
Then go to Settings -> Display & Sound -> Audio Output, and select Wired Headphone
