Also keep in mind that a lot of USB audio utilities add a good deal of latency 
into the mix, not a problem for listening, but it might well be so if your 
using a headset mic through the system.

Look at the various audio mixers that are out there.  I use an Alesis Multimix 
8 (It’s USB enabled to hook directly to a PC and has multiple inputs) It’s 
going to take quite a few cables and adaptors to make all that work though.  
You also may need  a larger mixer with more inputs depending on what all you 
want to add.  You also may need some type of isolation transformer if you plan 
to use your headset to talk on your radio if you get any hum. 

 

There is a lot of info out there you’ll need to do your research before buying 
though.  Example - a lot of mixers say ‘USB’but are not able to plugged into a 
PC - you can plug a memory stick with MP3’s into them is what they are 
referring to. 

 

Google and look for the following videos:

Hello all,

I am interested in adding a ham radio to my audio setup. I operate both my PC 
and game console over the same headphones simultaneously. However they give me 
issues sometimes depending on what audio equipment I use (eg, Video Monitor 
HDMI output. sound card output, or Zoom H4N Pro output), and I don't know how 
to isolate them to use whatever I want. I use Sony MDR-7506 headphones and I 
want to integrate my HAM radio equipment into the same headphone loop (I want 
to hear all at the same time, PC, Console, HAM radio). I was wondering if there 
are any ways of /or tools for isolating interference between headphone inputs 
and my actual physical headphones when I have several inputs (eg, game console, 
PC, HAM radio)
