How to connect a MacBook, a PC, and one headset with microphone

[javieradarosa]

Hello!

I have the following hardware:

• 
  - MacBook Pro Mid 2015 with one 3.5mm audio port (mic, ground, right, left)
  - Mic/Headphones splitter
  - Plantronics headset with 2 3.5mm audio jacks (both stereo)
  - 2 stereo 3.5mm audio jack cables
  - PC with 5 3.5mm audio ports (each works independently and can be assigned a function when a cable is connected)

Connected like this:

• 
  - MacBook to Splitter
  - Splitter Headphones port to 3.5mm audio cable to PC Line In port
  - Splitter Mic port to 3.5mm audio cable to PC Line Out A port
  - Headset Headphones jack to PC Line Out B port
  - Headset Mic jack to PC Mic In port

So far I have managed to get the Headphones and Mic working on PC and audio from MacBook coming out via PC to Headphones. But I can't make the mic sound to go through the PC to the MacBook.

If I plug in the mic directly to the MacBook, in the Input settings I see the buit-in mic turn into "headset mic". But when the PC line out is connected to the mic port, the MacBook doesn't detect an input and switches to built-in mic.

I need to make the mic audio from PC reach the MacBook.

Thanks!

Do Mac's support USB audio cards?

Yes. I wanted to avoid buying additional gadgets/hardware. I had seen something like this: http/prntscr.com/iim9sz for $15 approx. I know it's cheap but I want to figure out if it is possible to use what I already have.

Thanks for your message
