Chromecast Audio uses sounds to indicate user actions. Here's more on how you can customize playback sounds:
Start of cast session
Whenever you start a cast session, Chromecast Audio will play a playful sound in order to indicate a connection was made and playback is about to start. You can also use this time to adjust the volume to your preferred levels before the music starts. Note: The time it takes before music playback actually starts depends on the app you're using for casting.
When changing the volume of your Chromecast Audio through the music app or your Google Home app, your Chromecast Audio will play a short sound confirming a volume change was done.
Turn off playback sounds
- Make sure your mobile device or tablet is connected to the same Wi-Fi or linked to the same account as your Chromecast.
- Open the Google Home app .
- Touch and hold your device's tile.
- At the top right corner of the screen, tap Settings Audio.
- Turn off Playback sounds.
Full Dynamic range
Chromecast Audio supports Full Dynamic range output. This provides premium and professional audio equipment such as Hi-Fi audio systems, AV receivers, and monitor style speakers with the highest quality sound output.
When connecting your Chromecast Audio to such sound systems using 3.5 mm or RCA analog cable, you can turn on Chromecast Audio’s Full Dynamic Range option:
Note: Many common speaker systems such as desktop computer speakers, docking speakers, portable and Bluetooth speakers are not built to support such a Full Dynamic range, causing the volume level to be very loud and sound to be somewhat distorted. Avoid turning this setting on in those cases.
When Chromecast Audio is connected through an optical interface, it will always use Full Dynamic range. Setting Full Dynamic range to off won't have an effect as it will remain on.
