skype - How do I voice-chat with my friend on PC, sharing my screen and game audio without mixing in their voice?

I consider myself a tech-savvy person, but this audio-related problem I don't know how to solve.

Imagine the following situation: You're chatting with a friend using Skype to show them what's on your game screen. They can see the picture, hear you, but can't hear the sound from your game.

In Skype's audio settings, you can set input (what your friend hears) to your PC's sound mixer output. They will then not be able to hear you, but they'll hear both the game and their own voice.

I have tried using Teamviewer and streaming applications for this purpose, but my friend hears himself in addition to terrible lags and latency.

Using separate devices is also pretty bothersome:

• Show game and send it's audio via Skype (or any other app that can share screen) on PC;
• Chat with friend on another device (friend can use both apps on the same PC) while combining your own audio by using a 2-input → 1 output 3.5mm audio adapter (risky business on its own);
• Alternatively, use another voice chat app on the same PC and some configuration of virtual audio-mixers so that you can hear both the game and your friend.

There's gotta be a better way!

How do I properly configure my PC software so that I can:

• Voice-chat with my friend;
• Share my game's video and audio with them;
• They won't hear themselves speaking?

I have ran into a similar issue in the past while helping friends with some technical bits and bobs. I use Teamspeak for my Comm's (primarily for gaming purposes) but if a friend there needs tech support I jump on Teamviewer and I will hear myself on his sound and within Teamviewer you can mute the other person audio while they still hear you/can speak to you from the Teamspeak connection.

Obviously you mentioned you use Skype and I haven't actually tried doing the above with Skype but maybe Logmein might work for it if you turn off either your or their audio.

Like I said it might not work but maybe its worth a try.

Good Luck with it though :)
