MacBook Pro connected via toslink splitter: NO AUDIO

[fabiobi]

Hi there,

I've looked all over the web for an answer but couldn't find anything. Hopefully you'll be able to help!

I've been using my MacBook Pro to watch DTS-encoded movies connecting it through a fiber-optic cable (with a toslink adapter).

It works fine if I connect it directly to my home-theater.

Now I'm trying to connect it through this splitter, in order to easily switch between cable TV and the MBP:

When I do this no audio comes out.

The cable TV audio works fine when connected to the splitter.
The MBP goes on encoded audio mode when connected and sends audio.
I've tried changing all cables (3 of them) but it still won't work.
I've also tried switching inputs.

Any ideas?

The manufacturer believes it could be that the MBP sends a weak signal and, when sent through a splitter, it loses power.

Comparing MBP's signal with the one from my cable TV unit, it does look a bit weaker.

Does the manufacturer have one that can boost the signal coming out of the switch? I don't see a power supply hooked up in your pics, so it doesn't look like that one is doing anything to the signal at all.

A weak input signal would be negated by a built in signal booster.

I always thought that one of those that had multiple inputs, and a single output, was called a switch, while a splitter was usually one with a single input, and multiple outputs. I haven't kept up with the lingo on the audio equipment these days, though, so I could be off ... been over 10 years since I was into that stuff.
