Tried, and Failed to Connect My TV and my PC to the same Speakers using a Splitter

Hey everyone, this is a continuation of my last post, which is located here: Previous Post Regarding TV Volume on PC Speakers

Since this question is less of a personal solution, I figured if I made another post it will help someone else out!

So For those who haven't read my last post, I have an Nvidia Surround set-up with 3x Acer 23" Led Monitors. One of them I am using as my HDTV and is connected to the cablebox AND the PC Via an HDMI Switch.

Originally, I didn't want to choose to listen to EITHER the PC OR TV, and constantly plugging and unplugging.

I wanted to leave both connected at once, and leave it up to the user (me) that if I want to watch something, I can turn down the computer volume and vice versa.

So a few weeks ago when I decided to use this as my set up, I purchased a 3.5mm Male - To - 2x 3.5mm Female Adapter off of monoprice.
(which was tough to find, I couldn't find another situation where this cable would be needed.)

I was trying to do this (Drawing it out is much easier to explain I think) -

.........................................<< 3.5mm Female << 3.5mm To Computer
Speakers << 3.5mm Male To <<
.........................................<< 3.5mm Female << 3.5mm To RCA << To Cable Box Audio Out

(Sorry about the dots, the board doesn't detect spaces as placeholders)


Now when I hooked this all up, Instead of having full volume from both sources, I had a BARELY BARELY LOW volume and I could tell it was from the computer and the TV. So Both Signals WERE getting through, just extremely weak.

If I kept the splitter connected, and unplugged the TV from it, The Volume for the computer would return to full volume, and vice versa.

I still have the cables, but scratched the experiment and figured it was not able to be done. It had something to do with signal strength probably.

In my previous post, the conclusion was made that I needed a Pre-amp to solve my issue. And It got me rethinking about this setup I tried.

Do you guys know why this happened? And if signal strength IS the issue, if I put the pre-amp somewhere in the circuit, would it resolve that issue?

Thanks in advance for your help guys and girls!

Both signals are trying to go through the cable so you're basically getting 1/2 of each signal with that splitter - for my setup (gaming console + computer + other) I used this: TCC TC-716 6-Way Stereo Source Selector, you connect each source to it, and then use which ever one you want (say selector #6) to connect to your speakers. When you press button 1 (say your computer) and #6 you'll have sound from your computer, when you un click #1 and click #2 (your other device) you get sound from your other device.

If everything still isn't loud enough, you can connect #6 to an amp, and the amp to your speakers to amplify the signal (as the signal is too weak)

Hope this helps thumb.gif
