Hello there, need a little help finishing my setup.

My setup includes:

Sonos Beam gen2

BenQ tk700sti eARC supported 4K projector

I read a few articles online and follow the troubleshooting steps but nothing help.

Running out of idea and would need some help.

I went as simple as I could and ran an HDMI cable from the HDMI 2 slot of the projector to the Beam but the speaker won’t detect it for some reason ?

I’d guess there is a manufacturing fault in that cable. Based on those specs printed on it, I’d expect it should have worked….so I wouldn’t blame the installer except for not testing after installation. I was just lucky, just because it didn’t match the look of the Sonos cable.

Don’t overspend on HDMI, they’re digital, but you’d be looking for any HDMI 2.1 (high speed) type cable. I tend to use Belkins, bought from Blue Jeans cable, sometimes direct, some times through Amazon. Don’t get pulled in by the Monster Cable hype ;)

So is HDMI 2 the eARC connection? Have you tried HDMI 1?

Thanks for the suggestion. Yes, the HDMI 2 slot is the ARC connection, I tried switching to the different HDMI slots just in case but no success sadly

What are your audio sources and how do they connect to your system? We need a fuller picture (as it were).

I've only got 1 hdmi cable running from the projector to the beam. Nothing else is connected to either of them apart from power and the Android stick of the projector.

Here is a picture of the HDMI connected to the projector. Also a picture of the settings, I made sure to turn on audio return on the projector as well.

OK. What content are you playing from the Android stick? Is the picture working OK?

Please show settings for audio rather than display.

So far I've been playing off of YouTube and worked fine for the video but never could get any audio out of the sonos.

Couple of comments, which may or may not be helpful.

The HDMI cable in your picture doesn’t seem to be the one supplied by Sonos. Which raises the question of what level of HDMI compliance it is. It’s, at least in my mind, a 50/50 chance it isn’t fully HDMI 2.1 compliant, which implies full throughput and speed of data transmission concerns. Double check the type of cable it is. And, whichever cable you’re testing with, try reseating it at both ends to ensure full contact.
YouTube doesn’t transmit in a 5.1 compliant stream, only stereo. You’d be better off using a DVD/Blue-ray player attached to HDMI 1. . Or, if those are ‘internal apps’, pick one other than YouTube, for testing purposes.
