Completing the Sonos Arc setup for use with a projector

Hi Folks,

I just got a Sonos Arc with a pair of Era100s and a Sub (gen3). I would love to pair it with my BenQ W770ST projector that has served me well for movie viewing for the past 10 years. I know, projectors aren’t exactly the intended companion for Sonos Arc, especially old ones without eARC, but my research prior to purchasing the Arc indicated that it was possible if I set it up with an HDFury Arcana. So great is my desire to have this work that I purchased one of those too.

I got my projector’s HDMI cord connected into the “HDMI out” port on the Arcana. I connected the HDMI from my Sonos Arc to the “eARC” port on the Arcana. A third HDMI is connecting my XboxOne to the “HDMI in” port on the Arcana.

I initiated the set-up, which first asked me to turn on CEC on my “TV” (in this case projector). Fortunately my projector has the option to turn on CEC. However, the next part asks me to enable Audio Out on my “TV,” and here is where I’m currently hung up. I can find no Audio Out option on my projector. I can’t complete the step without it.

It’s got an audio jack for connecting other speakers or headphones, which doesn’t help me with the Sonos.

I am told that if I can manage to complete this set-up process, even if initially not with my projector, I can later connect with my projector without having to go through that set-up again. Is this true? If I find a friend who has a TV that can go through this set-up process, might I then be able to use the Arc with the projector? Is there some other way to get past this?

I have one shot at showing my fiancée Star Wars for the first time, and I want to make it awesome!

I sincerely appreciate any help you can give!

I’m pleased to say that this morning I seem to be up and running!😀

I did try rebooting everything, but that didn’t seem to work. I’m constantly starting fresh because I don’t have a set up that I leave put together. I keep my projector, Xbox, and now Arc all stored in their respective cases when I’m not using them, so they are not always connected to power. A bit inconvenient, but this way I worry less about dust/other damage.

I was noticing that on the Arcana display where the Arc should be showing up there was only “Beam ARC Active”. ARC being active sounded good to me so I didn’t think to do anything about that, but I watched videos showing other people’s Arcana screens and they didn’t have that. I decided to try setting “Somos BEAM1/ARC” to off. That didn’t seem like something that would help, but once I did, my Xbox began displaying more audio options including Dolby Atmos. It still wasn’t coming through the Arc when I selected it though, so I rebooted again and additionally switched “TV ARC routing” to off. This time, sound blossomed from the Arc and it was glorious. The projector, however, was making a very much less than pleasant sound as it presumably also tried to put out Dolby Atmos simultaneously. I turned the projector volume down to 0 and now I at least don’t hear the horrible sound. Maybe there’s a setting I can enable to stop the projector from trying to play the sound altogether.

I was able to complete the Sonos app setup and now I can use the Arc to show Star Wars this weekend! Thank you all so much for your help!!

Hi

it’s me again 🙂

You might try cables that are all rated for 4K (preferably the same brand) as you previously suspected might be an issue. At the very least you eliminate a variable.

Also there’s no need to spend over $30-$40 per cable (unless length is a factor).
