Using audio splitter has lowered the volume

[Shaorin]

I'm using an audio splitter so I can connect both ps3 & pc to the same pc speakers but the problem is the audio volume has been lowered. Is there a way to make both devices output volume higher?
Here's a diagram on how I setup my audio splitter https://forum.videohelp.com/images/imgfiles/PBCijwa.gif

You're not splitting audio, your merge two separate sources with a simple Y adapter. That could potentially damage the sources. Use an A/B switch (you will only hear one source at a time) or an audio mixer (to hear both at the same time) instead.

How will I plug the pc speakers to the switcher since it doesn't look like there are shops that sell 3.5mm input switchers

Use pinplug to RCA adapters or cables.
