Check the physical remote identity
Identify the remote as a Google TV Streamer Voice Remote, not simply any remote that controls a Chromecast. The documented ring feature depends on the supported remote being paired to the streaming device. A similar direction pad is not evidence that an older remote contains the same sound-producing hardware.
Google’s remote guide identifies an audio port for the chime. Its Find My Remote article explicitly includes both Google TV Streamer and Chromecast with Google TV as pairing contexts for the supported Voice Remote. Keep both the remote model and receiving device with your notes.
Use the correct trigger for the receiver
The back-button trigger belongs to Google TV Streamer hardware. Google says Chromecast with Google TV users must use a voice assistant or Google Home. In the Home app, select the intended TV device and use its Find my remote control to play the sound.
Confirm the selected room and device before triggering a chime in a household with several screens. The article describes a thirty-second sound and says pressing any button on the found remote stops it. An alternate physical or virtual remote can also expose the feature through Google TV settings.
Keep a pairing problem separate
If the expected remote does not ring, note whether it was actually paired with the selected receiver. A remote that has been replaced or moved between rooms may no longer be the one associated with that device. Repeatedly invoking the wrong room’s control cannot establish that the remote’s speaker failed.
For help, provide the physical remote model, receiver type and whether the assistant, Home app or settings route was used. Do not search for a Streamer back button on Chromecast hardware or assume that every older Voice Remote supports ringing. The product pair and trigger route explain the apparent difference between otherwise similar Google TV setups.
