HDMI-CEC Volume Control on Aero

CEC Volume Control is a new setting introduced in software update 19.1021.153. When enabled, your Aero’s remote controls the volume on your TV, soundbar, or AV receiver over HDMI-CEC, instead of adjusting the Aero’s own internal volume.

It is switched off by default because compatibility varies. Some TVs and audio devices support CEC volume commands well, while others do not support them at all.

Before You Turn It On #

Set Aero’s own volume to maximum before enabling CEC Volume Control.

This gives your TV, soundbar or AV receiver the strongest audio signal to work with. Once CEC Volume Control is enabled, the Aero remote will try to control the connected device’s volume instead of Aero’s own internal volume.

If Aero’s volume is set low before enabling CEC Volume Control, the sound may stay quieter than expected.

Compatibility #

CEC Volume Control depends on the device connected to Aero and how that device supports HDMI-CEC.

Many TVs, soundbars and AV receivers do work. In testing, CEC Volume Control has worked with many Sony, Philips, Hisense, Fire TV and Android TV models, as well as several soundbars and AV receivers.

That said, we cannot guarantee compatibility from the brand name alone. Compatibility can vary even within the same brand. For example, one Samsung TV may support CEC volume control while another Samsung TV may not. The same can be true for other brands and model years.

HDMI-CEC normally treats the TV as the hub for connected devices. This means that if your TV does not support this volume control mode, a soundbar or AV receiver connected through that TV may not work with Aero’s CEC Volume Control either.

LG TVs do not support this CEC volume mode. If your soundbar or AV receiver is connected to an LG TV, CEC Volume Control is unlikely to work, even if the soundbar or receiver supports HDMI-CEC.

The best way to check is to make sure HDMI-CEC is enabled on your TV, soundbar or AV receiver, then turn on CEC Volume Control on Aero and try the volume buttons. If it does not work with HDMI-CEC enabled on your other device(s), it is unlikely to work with that setup.

Future Possibilities #

We’re looking into an alternative infrared (IR) volume control mode for a future Aero software update. This would let the Aero’s remote control your TV or AVR using infrared signals (the same way most universal remotes do), rather than HDMI-CEC. That would mean your Aero could control volume on devices that don’t support CEC, including LG TVs.

There’s no firm date for this. We’ll share more as it gets closer.
