I have Bose Q15 headphones that have a microphone. When I plug them in my iPhone or in my Macbook the mic works fine.

My PC has separate inputs for audio and mic. I purchased a Startech MUYHSFmm mm 3.5 mm 4 Pin to 2X3 Pin 3.5 mm Headset Splitter thinking it would make it work but it does not.

I get sound but I can't get the mic to work. When I try to setup the microphone using Windows's "Setup a microphone", it does not work.

The driver is ASUS Realtek Audio HD. I was able to tell the Realtek software that the device I plugged in the mic input is a mic. But I can't get it to work.

Did I buy the right thing? Is it a software issue?

Note that I have successfully used USB microphones on this PC but I never tried to use the 3.5mm jacks before.

  • The microphone jack takes a 2-conductor (aka mono) plug. The splitter you have has two 3-conductor (aka stereo) plugs. You could try a 3.5mm stereo jack to 3.5mm mono plug adaptor, but no guarantee that it will work. If you can solder, then cut off the mic stereo plug and replace with a mono plug. – sawdust Sep 11 '14 at 1:24

I uninstalled ASUS Realtek Audio HD completely and let Windows handle all audio stuff. It works like a charm. So the Startech MUYHSFmm mm 3.5 mm 4 Pin to 2X3 Pin 3.5 mm Headset Splitter that I bought was the right thing...
