[SOLVED] What do I need to plug in both speakers and headset (w/ mic) in one 1/8" jack?

[adamthemute]

Hey there, I'm trying to be able to have my speakers and headset (with mic) plugged into the same 1/8" PC jack. They won't be used at the same time, but just so I don't have to unplug/replug all the time (is that bad for the hardware to do that?).

So I bought this Y splitter that I thought was the right one, but I cannot get it to work. If this audio path below is correct, did I purchase the wrong one or is the cord faulty? Thanks!

hard to say without knowing what adapter you are using, possible you are using a PC/headset adapter that will split the headphone and mic like this one where you need a 3.5mm splitter like this one​

Nice diagram - very helpful.

Question:

Do you use the microphone? And the "Y" splitter between headphones and PC (PC-Green , PC-red) does work - correct?

Two things to consider:

1) TS, TRS, TRRS - meaning connectivity of the plugs and ports.

FYI:

Meaning that you must have compatible physical connections.

2) How do you plan not too use both speakers and headphones at the same time without unplugging one or the other?

If plugging and unplugging is awkward or difficult because you need to go under or behind a desk etc. you can simplify that with a simple audio M-F stereo 1/8" (3.5 mm) extension cable.

Plug the male end into the port you labeled PC-Green and leave the female port/plug up on the desk so you can easily plug in either the green speaker plug or the green headphone plug.

What you must also be careful about is setting up a ground loop between the audio components.

Expand your diagram a bit and it is very likely that one of the resident audiophiles will be able to offer further suggestions.
