Reddit reviews Monoprice 105557 Blackbird 4x1 HDMI 1.4 Switch HDCP 1.4 with Toslink and Analog Audio Extractor 1080p@60Hz

Does the hdmi switch have an optical out? If not, there are hdmi switches with an optical output that is what you need.

Yes you need a switch or a receiver to split the audio. I have a projector too and a Sonos Beam via optical. There are probably better ones but this is what I bought last year and it works great.

Yep looks exactly the same.

Edit here is the Amazon link for the monoprice one I posted. This one just actually claims Dolby TrueHD and DTS. Still need to find a tinting tape for those LEDs. Maybe sugru

I use https://www.amazon.ca/gp/product/B003L14WB8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 for that exact reason. It works like a charm and did not break the bank. On the plus side, if you use a Logitech Harmony remote, it will control the switch for you.

The monoprice hdmi switcher + toslink (optical) is what I use to send sound to my surround system, as well as quickly switch between HDMI signals (computer, PS3, PS4). It works great except for one thing... the frequency used by the W1070's remote control is the SAME as that of the monoprice box. That means I can't control the projector without switching the signal on the HDMI box! So maybe your best bet is to find something similar, so that you don't frustrate yourself.

I had the same issue with a black Friday special Samsung TV. Luckily I don't watch TV and use all external devices, Roku, BluRay and PS4. I used the monoprice receiver to output audio to my amplifier

If you get an hdmi switch that splits optical you need not plug the playbar into the projector at all. I currently use one because my tv does not pass 5.1 (which is also a possibility with your projector). Plug all your sources into the switch, plug the optical out from the switch to the playbar, and the hdmi out from switch to the projector. You will just need a long hdmi cable.

I use this switch

(I was on my phone before)

edit: Like I said, it didn't last long. Also, I remember my PC video card didn't like it. All other devices seemed to work fine. It was even programmable through my Harmony Remote.

AFAIK you'd need a converter like this one. Or if you don't want to mess around converting video signals, an HDMI switch would also work.

It might be cheaper to get an AV selection switch that lets you plug in multiple hdmi sources with one video output an maybe a couple different audio outputs. Then get a Yamaha with audio and phono inputs. Get one of those for $100-$150. Or an SMSL type desktop amp with Analog and Phono in.

I don't think it does. [This] (http://www.amazon.com/Monoprice-Switcher-Toslink-Digital-Coaxial/dp/B003L14WB8/ref=cm_wl_huc_item) Monoprice device has DAC i think.
