I’d put a splitter in between the AppleTV and the Optoma, rather than after it. Not sure what your “HDMI converter” is in this case, but ideally, an HDMI splitter could send the video to the Optoma, and pull off an optical output in full Dolby Digital and send that to the Sonos converter, which would play the Dolby Digital signal. Ah… perhaps your HDMI converter is the Sonos converter, that makes sense.
So, yea. Put a HDMI switch with an optical audio out on it in between the Apple TV and the projector, and pull the audio out before it hits the projector. That way, you’ll get the full surround affect.
I’m not familiar with the Optoma specifically, so you may want to double check the Apple TV’s audio output to ensure it’s sending out a Dolby Digital (and not Dolby Digital Plus, or Dolby Atmos, or “Best availalable, lock it down to DD only) signal. It might be that the issue isn’t so much with the processing of the audio signal in the Optoma, but in what the Apple TV is sending out. Worth looking at, at least, before spending $50 or whatever on a HDMI switch.
Yes the idea is to “split” the output of the Apple 4K tv into two HDMI cables.
One with video going to the OPTOMA (this should be easy 4k video)
One with audio to the SONOS BEAM (need to make sure it will then provide the right audio to the BEAM)
Do these splitters exsist?
Ah, that’s more challenging. Finding a splitter that can take a regular HDMI input and create a HDMI ARC output is more rare. I’m not overly familiar with many of those….the only one I know of (not that there might not be others) is the HDFury Arcana device, which has the necessary electronics to create a ARC signal from a standard HDMI signal. That’s generally the province of the TV electronics. And I’m not sure how that would work for a Beam, since it creates an eARC signal. I think that’s backwards compatible to ARC, but I’m not 100% sure, it would be worth asking the folks at HDFury about that.
It’s also why I suggested the more prosaic optical output device. There’s tons of those, and they’d be much cheaper, and you wouldn’t lose any signal fidelity due to the fact that optical can only handle Dolby Digtal anyway, since the Beam isn’t capable of higher audio formats.

I heard about the fury range, wonderful machines! and indeed i found one that could split the received HDMI signal from the Apple 4k tv into two identical hdmi outputs. one for the beamer and one for the sonos beam.
I do like what you say about a device that would split a hdmi in into a hdmi out (without loss) and a SPDIF dolby sigital.since the fury is there for a 300,- EURO i guess a SPDIF device would work for a lot less…. its a pitty that my Optoma projector does have an optical out but only provides stereo through this fiber output…. doh…
Thank you!
