@ECHO off
:: Script by /u/dark_skeleton updated on March 26th, 2021

:: Hey! Thanks for reading. /u/dark_skeleton here, if you notice any bugs contact me on reddit!
:: This script will attempt to fix:
:: - Broken THX audio.
:: - No THX audio output.
:: - Muffled THX sound.
:: - Extremely bassy THX sound.
:: - Greyed out app list in Synapse Mixer tab.
:: - Synapse not actually toggling Stereo/Surround on Mixer tab
:: - High CPU usage by Windows Audio Device Graph Isolation (as a side-effect lol, might be faster to just kill the task sometimes).

:: Please note that this script is not omnipotent and you might have to execute it any time you realize THX breaks
::        since Synapse is still buggy and that's probably not going away anytime soon.
:: Supported headsets
:: - Nari Essential, Nari Wireless, Nari Ultimate
:: - Kraken TE, Kraken Ultimate
:: - Razer 7.1 Surround standalone app

:: Changelog:
:: v1.2 - I literally don't remember 
:: v1.3 - Sped up execution by removing a bunch of delays and skipping restarting Razer Central and other stuff that wasn't affecting audio
:: v1.4 - Had to bring back restarting Windows Audio service, as some people (incl. myself) reported mixed results every now and then. Sadly this means all audio will stop for a second and some games might crash
:: v1.5 - Added standalone 7.1 Surround app support

:: 051A is THX for Nari Ultimate
:: 051C is THX for Nari
:: 0520 is THX for Kraken TE
:: 0527 is THX for Kraken Ultimate
:: 22AD seems common for all headsets except standalone version of the THX Surround app
:: For standalone we need to kill RZSurroundHelper.exe, RzSndSrv service, and rzappengine.exe
:: If you have a headset that's not listed above, please contact me on reddit! I will need your help to add it so please be prepared to answer some questions
