You don't need Voicemeeter or Virtual Audio Cable for this anymore! On PC, the free Audio Radar desktop app keeps your game on the light bars and everything else in your headset.
Get it at audioradar.com/start. With it, your headset plugs into your PC the normal way. The PC Setup Guide walks you through setup.
Go to User Settings > Voice & Video and set Output Device to your headset or speakers, not Audio Radar.
In your game's audio settings, set the voice chat output device to your headset or speakers, not Audio Radar.
Play it through your headset or speakers, not Audio Radar.
Your game stays on Audio Radar, so only game sounds reach the lights.
Already have Voicemeeter installed? Close it fully before you install the app, the two conflict.
On console? See Do the light bars activate when teammates are talking? for Xbox and PlayStation.
