Step 1. Obtain a copy of VAC (virtual Audio Cable) full version unless you like "TRIAL" playing in your ears every 10 seconds. Step 2. install In TS make sure output is set to your headset not default Load up VAC control panel and 2 copies of the Audio repeater (you may have 2 types, KS and MME, load one of each) In the KS version select wave in as your sound card ("Realtek HD Audio Stereo Input" for me) Select output as "Virtual Cable 1" In the MME version select input as Line 1 (VAC) output as your headset. select Line 1 as your default playback device in your sounds control panel. Press start on both repeaters. Now TS goes direct to your headset whilst system sounds get routed to line 1 then routed again to headset. Xsplit picks up the default which is now line 1. Hope that makes sense for a quick guide.
