Use Homepod speakers also for non-Apple devices and without HDMI-ARC screen? Yes, it works.
The current version of the Apple TV 4K "Generation 2" supports HDMI-eARC. For example, if Homepod speakers are connected wirelessly, Apple TV can play TV audio through them. Provided the TV has HDMI-ARC or HDMI-eARC. The audio playback from the Apple TV also works, of course. But what if a non-HDMI-ARC video projector or monitor and a game console are used? Then, due to the lack of HDMI-eARC, playback of this external HDMI source is not possible.
Use external HDMI sources with Apple TV 4K & Homepod
Here our helps VAX04101 HDMI eARC switch. This allows up to 3 external sound sources to play back the sound via Apple TV - even in higher audio formats such as Dolby Atmos. The whole thing is connected as follows:
Playback from the Apple TV is also possible without changing the plug. To do this, switch off eARC on the HDMI switch and switch to Apple TV input 1 - conveniently using the remote control or on the device. The VAX04101 then delivers the video signal from the Apple TV to the projector or monitor, while the sound is played back via homepods.
So the VAX04101 is not just an interesting solution for an HDMI-eARC soundbar. Additional HDMI sources can also be operated in a scenario in which the Apple TV 4K is the sound system.
