Welcome iHateUpdates,
I understand you'd like a reliable way to preserve your preferred audio configuration, particularly with “Audio enhancements”, “Spatial sound”, and the microphone settings.
Rather than exporting audio-related entries from “Registry Editor”, I would not recommend restoring individual audio registry keys. These settings can be associated with the particular audio device and its driver.
For your current configuration, I suggest these options:
- Set Audio enhancements to Off from Settings > System > Sound > select your output device > Audio enhancements.
- For Spatial sound, open Settings > System > Sound, select the playback device, and verify your preferred Spatial sound setting.
- If your main goal is to have a recovery point for Windows system and registry settings, consider creating a System Restore point after configuring everything as desired. System Restore can return system files, registry settings, and installed programs to their state at the time that restore point was created. System Restore
Looking forward to your update.
