Help & troubleshooting

Make sure the phone and receiver are on the same Wi-Fi network and subnet - mesh systems, guest networks and IoT VLANs can isolate devices. On the receiver, Setup → Network → Network Control must be On. Re-check the IP against the receiver's own Network → Information screen, since DHCP addresses change. HTTP is required; Telnet and HEOS are nice-to-have. Full steps on the getting started guide.

Receiver Telnet ports can get sticky after long uptimes - power-cycle the receiver from the wall to clear the listener. On Wi-Fi 6 mesh, force the phone onto the same band as the receiver (AVRs usually sit on 2.4 GHz; phones prefer 5 GHz).

It comes down to your network, not just the model. If the receiver's web portal, the HEOS app and the official Denon/Marantz app can all reach it, AVR Maestro should too. See the supported receivers page.

Receivers report volume as absolute (0-98) or relative (-80 to +18 dB). The app handles both; if you recently changed the receiver's volume-display setting, restart the app so it re-reads the scale. You can flip which value shows on top in Settings → Audio.

Surround modes and features are gated by the input's audio format and the active sound mode - a 2-channel source won't enable Dolby Atmos. That's the receiver's behavior, not the app's. Tap the (?) next to an N/A pill for the exact requirement.

Tabs are model- and mode-aware. Audyssey, Dirac Live, IMAX, Auro-3D, Surround Shape, Distances and Crossovers only appear on receivers that expose them. Check Settings → Devices → Device Information to see what the app detected, or re-add a hidden tab from Settings → Customize Tabs / Customize Navigation.

Radio is capability-gated: it only appears on receivers with a built-in FM/AM tuner. If yours has one but the tab is hidden, confirm the tuner appears as an input on the receiver and re-enable it from Settings → Customize Navigation. See the Radio guide.

The current input doesn't expose metadata - analog, optical/coaxial and most HDMI passthrough sources don't report track data. For HEOS sources, tap Launch HEOS to start playback, then return and the metadata populates.

On some pre-2025 receivers (X4500H / X6700H / S960H / X4700H class), the receiver can't serve the Speaker Layout or Subwoofer Output screens to the app, so AVR Maestro hands you a one-tap button into the receiver's own web control for those edits. Everything else works normally; newer firmware serves every screen in the app.
