Just open the settings of your favorite game or media player and select real 7.1 or 5.1 audio output. Do not use any additional in-game virtualization setting (like a “headphone” or "3D audio" profile).

Features:
<ul><li>Enable/Disable seemlessly, &lt;em&gt;without&lt;/em&gt; changing your default device, writing config files or restarting the audio service</li><li>Drop in your own &lt;em&gt;HRIR WAV files&lt;/em&gt; as virtualization presets, same as &lt;em&gt;HeSuVi&lt;/em&gt; on Windows</li><li>Run it in the background with a &lt;em&gt;system tray icon&lt;/em&gt; (enable it in the app's settings)</li><li>Compatible with &lt;em&gt;EasyEffects&lt;/em&gt; and most similar apps</li></ul>
Please note: This app requires the PipeWire audio system. Recent Linux distributions use this by default, so don't worry about it.
