Google separates advanced sound-format selection on named Chromecast/Streamer models from an Output format control available specifically on Google TV Streamer. Identify the device first, then use a format supported by the complete connected audio route.
Identify the actual Google hardware
Record whether the device is Chromecast with Google TV HD, Chromecast with Google TV 4K or Google TV Streamer 4K. An unrelated Chromecast generation or a television with Google TV built in should not inherit these exact instructions automatically. Also identify the TV, receiver or soundbar and physical HDMI route.
Keep the current audio track, output format and listening destination in a private note. A format name shown in a menu is not proof that the selected programme supplies that original track or that every intermediate component can handle it.
Choose the applicable control
Use the current Google guide and the actual device menus.
| Device/control | Documented route | Scope |
|---|---|---|
| Named Chromecast with Google TV or Streamer advanced selection | Display & Sound > Advanced sound settings > Surround sound format selection > Manual. | Select only the supported formats needed for the equipment. |
| Google TV Streamer output format | Display & Sound > Audio options > Output format. | Streamer-only control; Automatic or a supported specific choice. |
Keep automatic and manual decisions distinct
Google recommends the automatic output choice for the Streamer and warns that selected formats need matching equipment support. If a manual comparison is necessary, first read the TV and audio-system manuals for that route. Do not enable every format merely because it is listed.
Use one authorised scene and one change. Record the original value, choose the documented supported alternative, and observe audio as well as picture. Follow the current device guidance if a power cycle is needed for the setting to take effect. Do not combine format changes with new account details or several different cables.
Interpret the result by layer
Record the model, actual menu, connected audio route and one before-and-after value. Confirm the required audio as well as picture on the same permitted item.
| Result | What to investigate next |
|---|---|
| Supported choice restores sound | Keep the exact route and before/after values. |
| TV speakers work; return route fails | Check the TV/audio-system path and supported format. |
| Only one selected track fails | Inspect source track and player handling. |
| All routes remain silent | Use the broader destination/mute/audio workflow. |
