- ⚠Bluetooth headphones not supporting the required codec
- ⚠Game or app overriding system spatial audio settings
- ⚠Sample rate mismatch between app and audio device
Solutions

- 6Or: DTS Sound Unbound (paid, requires DTS app)
- 7Test with a spatial audio demo: search "Dolby Atmos demo" on YouTube
Solution 2: Fix Greyed-Out Spatial Audio
- 1If the spatial audio dropdown is greyed out:
- 2Check audio device format: Sound settings → device properties → Advanced
- 3Set format to: 24-bit, 48000 Hz (Studio Quality) — spatial audio requires this
- 4Disable "Audio enhancements" — they can conflict with spatial processing
- 5Update your audio driver: Device Manager → Sound controllers → Update driver

- 7Bluetooth: only stereo mode (A2DP) supports spatial — Hands-Free mode does not
Solution 3: Fix Spatial Audio Quality Issues

- 3Disable ALL other audio enhancements first:
- 4Sound settings → device properties → Advanced → uncheck "Enable audio enhancements"
- 5Also disable any manufacturer audio software (Realtek, Nahimic, Sonic Studio)
- 6These programs apply their own spatial effects that conflict with Windows Sonic
- 7If audio desyncs with video: try a lower sample rate (44100 Hz)
Solution 4: Set Up Dolby Atmos
- 1For Dolby Atmos specifically:
- 2Install "Dolby Access" from Microsoft Store
- 3Open it → choose "Dolby Atmos for Headphones" → purchase or start free trial
- 4After activation: spatial audio dropdown will show "Dolby Atmos for Headphones"
- 5For Dolby Atmos on home theater (speakers/soundbar):
- 6Your receiver/soundbar must support Dolby Atmos
- 7Set Windows output to the Atmos-capable device
