Troubleshooting
VRROOM: no Dolby Atmos from Apple TV, Shield or Netflix
Your sound system reports 5.1 instead of Atmos with an HDfury VRROOM in the chain. Nearly always a source or app setting silently caps the audio — check these in order.
Fix it step by step
- Apple TV 4K: go to Settings > Video and Audio and make sure Change Format is OFF. With it on (a common workaround from before the VRROOM), the ATV4K won’t detect the VRROOM as Atmos-compatible. Confirm Atmos shows as available under the audio settings.
- Netflix (any device): log in to your Netflix account on a computer and set the playback quality to High — on lower settings Netflix never serves Atmos, even when other apps do. Restart the source afterwards.
- Nvidia Shield: Atmos availability depends on the model (2017 vs 2019/Pro), the app and the advertised EDID. With an SDR-only display, use an SDR EDID — but know that Disney+ and Netflix withhold Atmos in some 4K SDR modes on the 2017 model. Reboot the Shield after every EDID or scaler change. For Prime Video, try turning Dolby Audio processing off.
- Check the app’s own display. Some apps show 5.1 in the title menu yet switch to Atmos during playback once the device reports Atmos capability — play a known Atmos title (The Mandalorian on Disney+, The Old Guard on Netflix) and read the format on your sound system, restarting the app first for an accurate readout.
- Verify the VRROOM EDID. In the web server’s EDID section, make sure the EDID presented to the source includes full audio capability (the default 8K60-420 FRL-5 VRR HDR bank has full audio). If you use Automix, set AUDIO CAPS to a sink or mode that includes Atmos.
- Using TV ARC (not eARC)? Atmos over ARC needs DD+ and an HDMI cable that handles 192kHz ARC — a cable can pass 600MHz video yet still fail 192kHz audio. Also set [ARC HBR] appropriately and note that regular ARC never carries TrueHD-based Atmos: that needs eARC.
Remember the manual’s ground rule: VRROOM never converts audio — what comes in goes out. If Atmos doesn’t arrive, the source isn’t sending it; these settings make it send.
Do you need a VRROOM for this?
Yes, if…
- your AVR or soundbar can decode Atmos but sits behind a TV or chain that can’t deliver it — VRROOM feeds it directly from any source or from an eARC TV
No, if…
- your sound system doesn’t decode Atmos — no extractor can add a decoder it doesn’t have
- source, TV and audio system are all eARC-capable and connected correctly: fix the settings above instead of buying hardware
