If I bought an old Gen 1 sonos connect and connected to the 3.5mm audio out on my epson eh-tw7000, could I then send that audio wirelessly to a Gen 1 sonos beam?

This isn’t the way to go for Sonos audio with a projector, IMO.  In fact, Sonos HT products are really designed for TVs, but can be made to work with projectors.

Generally it is better to split the audio from the video and send the audio straight to the Beam rather than through the projector.  The best solution for this is one of the newish ‘HDMI-ARC/eARC splitters’ that have recently appeared.  It does mean a longish cable somewhere.  \this is in the nature of a system in which the picture is produced a long way from where the audio has to come from.

Forget the Connect.  It isn’t intended for AV applications.

You can, but the analog line in imparts a 75ms buffering lag, which will throw off lip sync.

    Hi.  You could, but it would only play in stereo and there would be an audio lag of at least 75ms, which is enough to cause lip synch issues, which may or may not bother you.

      Thanks for this, I did not know about the lag.

      Would it make any difference if I extracted the audio (from an Amazon fire stick 4K max) via a cheap neoteck hdmi audio extractor (I’ve got one of these and it’s a pretty good product) and then went from the neoteck into the optical port of the sonos connect instead? Would that sort out the delay?

      The optical is an output, not an input.

          Thanks for this. Not really sure what to do. The cinema system I have inherited has extremely inaccessible wiring. (The existing cable goes up the chimney breast and inside the ceiling recess.)

          John B - what I don’t quite get is why the new HDMI splitters, like the arcana fury for example, which split the signal into audio and video, work any better than just a normal (and much cheaper) 4K splitter? Can you not just send a normal HDMI (including video) signal to the sonos?

          Because Sonos works using an HDMI ARC signal, not an HDMI signal. This implies some sort of electronics that creates the ARC signal, which is normally part of the display (TV set). The ARC signal is not generated by sources devices, they send only standard HDMI signals.
           

          What is ‘special’ about devices like the HD Fury device, and likely why they’re not a inexpensive as a regular switch, is that they contain those electronics that take the standard HDMI signal, and create an ARC (or eARC) signal that can then be sent to Sonos.

          Oh i seeeeee. I didn’t realise this.

           

          so: if I have an AVR with an ARC output (a denon avr x-3300w) could I split this output with a normal 1 in 2 out hdmi splitter like the one in the link below, and then send one to the sonos beam Gen 1, the other to the projector?

           

          or would the sonos friendly arc signal be lost by virtue of being sent through the splitter?

          Most splitters either discard and/or ignore the ARC signal on the pins/parts of the cables that carry it. You may want to confirm with Portta about that particular device, I have no familiarity with that brand.
