Audio optical switch (not splitter) to feed Sonos or AV receiver

Greetings, first time poster.

I thought I had a simple solution to the lack of a headphone connection in my Sonos setup. And I was not interested in spending money on a Connect if I didn't need to.

Why not, I thought, have an optical audio switch in line before the signal goes to the Playbase? So the audio connection would be from TV into the switch, and the switch would have two optical audio outs. One would feed the Playbase, and the other could go to my AV receiver (which is no longer the main source of output now that I have my surround setup)(a Playbase, a pair of Play:3's and a Sub. The AV receiver is perfectly fine, just unused) With a switch in line, I could choose only the output I wanted.

My plan works great by manually unplugging from the Playbase, and then plugging into my AV receiver. I plug my headphones in to the AV unit, and I get my desired effect: headphone sound for me, and no output from the surround to wake up my wife. When I want to switch back to the surround, I unplug the optical audio cable from the AV unit and plug back into the Playbase.

Obviously, that's not a practical solution. Moving equipment around to get access, wear and tear on the end of the cable, etc. However, there doesn't seem to exist just an audio optical switch with 1 in and 2 out, or even a 1x3.

There's a ton of 3x1 switches (3 in, 1 out) and a ton of splitters. But splitting the signal means that both the surround system and the AV receiver would be outputting sound, not what I want.

I am really surprised that something as simple as this doesn't exist, or at least seem to.

Anybody else ever attempt to do this?

Here you go.

other alternative would be use HDMI-ARC out of TV if you have it and then get box that extract HDMI-ARC to toslink and rca.

Hi Chris, thanks for coming up with that link! If I understand it correctly, I could
  1. Connect my headphones directly into that unit (but would audio still get passed through Toslink, so that the headphones and the surround system are producing sound at the same time?... I’m guessing it would)
  2. Feed the L and R RCA outputs into my AV receiver.
Maybe I’m misunderstanding, but it appears to me that this is more of a splitter than a switch. Please correct me if I’m wrong.

I do appreciate your help, I’m determined to get this resolved.

Use a powered optical splitter. If necessary it could be powered from a TV USB socket.

The signal would be live to both Playbase and receiver. Simply mute the Playbase or turn off the receiver when not required.

Yea just turn down or mute the one you don’t want playing.

Thanks, guys. I've got a toslink splitter I can try out tonight. I'll see if i can mute the surround system while still sending a signal to the receiver.

So what you're also telling me is that the device I've described doesn't exist. I am surprised, it's just a reverse setup of a basic toslink 3x1 switch.

Well, there you go, world. Someone create one, and you've got at least one sale. 😄

What are you converting the tos link to for your headphones. Or does the headphone receiver have optical in?

My receiver has optical in. I plug my old school headphones into it. This receiver was being used for my previous setup for audio output from my current TV, a Samsung 60" LED (if that matters). It was a stereo setup, not a surround system.

Plugging in the headphones to the receiver would cut any other audio output. For my needs, it was perfect.

One-to-many splitters are just that. Adding individual output port on/off switches would involve excessive complexity.

They're not the equivalent of a selector switch in reverse.

Granted, I'm no electrical engineer, but if a selector switch can be set for a 3x1 on the input side, then I'm at a loss to understand why 1x3 is excessively complex on the output side. The signal doesn't go through a conversion, it simply follows a path. And if there's a gate, NONE SHALL PASS. (Sorry, love my Monty Python)

Anyway, feel free to school me, I'm always eager to learn stuff.

Simple splitters are rarely used as switching devices. They're used to send a signal to multiple devices simultaneously.

In a typical 1-to-3 splitter, a switch would have to allow for 7 combinations of active output ports. An unwarranted complexity.
