I have a Sony Bravia HDX-589w and my damn optical port is dead (no red light when receiver is on). I have a digital coaxial port on it that can be used. The problem is my PS3 and DVR/cable box only use optical. I have found several posts, sites, and posts leading to sites that either:
1. discusses a 1:1 optical to digital coaxial converter: http://www.smarthome.com/81261/Optical-to-Coaxial-Digital-Audio-Coupler/p.aspx ;or
2. discusses a 3-port optical switch (allows up to 3 optical devices to connect to one optical device):http://www.monoprice.com/products/product.asp?seq=1&format=2&p_id=2946&CAWELAID=1329448145&catargetid=320013720000010661&cadevice=c&cagpspn=pla&gclid=CIiy2fWwlbkCFchxQgodKyQATQ ; or
3. discusses a 1/1:1/1 optical/digital coax input to optical/digital coax output (so you can have one of each to connect to another of one): http://www.allaboutadapters.com/2diauscowopa.html

Ideally, if I could find, or if I could be directed to a site that sells a device that would allow me to connect my PS3 and DVR to my receiver (remember, i need 2 digital coax into 1 optical), I would be good to go.

You mean one device that converts optical to coax and switches? I don't think they make one device like that.

If you combine the Monoprice switch and then go into a Monoprice converter, it would work:

I don't know of any devices that combine a switch with a converter. You're probably going to have to buckle down and use 2 boxes hooked together.

Hi SomeGuy,

Before investing in any boxes, are you sure that the digital-coax output works?

Internal to the AVR, digital-coax and optical Toslink are the same signal. Many devices (maybe most devices) use the same driver to drive both the coax line and the optical LED. So it is possible that the coax output died at the same time as the optical output. You may want to test it, if you haven't already.

"You mean one device that converts optical to coax and switches? I don't think they make one device like that." - Tulpa

Honestly, the concept of these switches and converters is new to me, so I don't know if that's what I'm referring to. What I do know is that the optical port on the receiver is inoperable, so I wanted to connect my PS3 and DVR to the digital coaxial port. However, PS3 and DVR both use optical only. Ergo, my inquiry is does such a device exist that will allow two optical cables to be input while allowing a digital coaxial cable as output. Consider the amount of time I've spent scouring the WWW, I'm guessing no such device exists.

Hmmm... Interesting idea. I'll have to consider this after I test the coax, as was suggested by MarkHotchkiss.

@MarkHotchkiss

Thanks for bringing that up. I didn't know this. Perhaps this explains why I didn't hear any audio when using a poor quality cable. I'll test it again just to be sure. For the sake of clarity, if I remove the HDMI cable that currently connects receiver to TV, and use the digital coaxial cable instead, I should hear still sound, provided the coax port is working, yes?

No single device exists, but there are optical switches (allowing for DVR and PS3 use) and optical-to-coaxial converter boxes. Using one of each will achieve your goal. Monoprice has both. Should get them for under $30 for both units and any additional cables you may need.
