To customize the sound format on your Chromecast with Google TV (HD), Chromecast with Google TV (4K), or Google TV Streamer (4K), adjust your advanced sound settings:
- Turn on your Google streaming device
go to All Settings
at the top right of the TV screen.
- Select Display & Sound
- In the section Supported formats, select the format you want to use.
go to All Settings 
at the top right of the TV screen.Control volume with voice, phone, or smart display screen
You can set up your Chromecast Voice Remote or Google TV Streamer Voice Remote to control the volume on your streaming device instead of your TV, receiver, or soundbar. If you choose this option, you can control the volume in the following ways:
- Voice control on a speaker or smart display
- A phone or tablet with the Google Assistant or Google Home app
- Touchscreen control on a smart display
- The Voice Remote volume button
Important: You might experience unexpected results because of a disparity between the streaming device's volume settings and the volume settings on your TV, receiver, or soundbar. For example, if you mute your TV with the remote that came with it and then try to change the volume with your voice, your TV will stay muted.
- To start setup, go to All Settings
