Yamaha 客户常见问题解答

To make the volume louder from the sound bar, use the remote control provided with the sound bar. There should be a volume control button that allows you to adjust the sound directly from the sound bar. Ensure that the sound bar is properly connected to the TV and that any necessary settings on the TV are configured to use the sound bar as the primary audio output.

If the volume on your Yamaha 2090 soundbar has stopped working after a reset and reconnecting the cables, check if the soundbar is set to the correct input source. Ensure that the TV or device connected to the soundbar is functioning properly and the volume is turned up on that device as well. Additionally, inspect the remote control batteries and try using the buttons on the soundbar itself. If these steps don't resolve the issue, it may require further troubleshooting.

Sorry you're having trouble with this. After downloading the firmware, ensure it's the only file present on the USB drive. The drive should be formatted to FAT32, and the firmware should be in the root directory (not within any folders). Once you insert the drive, the Yamaha receiver should automatically recognize the firmware. If it still says "not found", double-check the firmware version and possibly redownload it. If after doing all this you continue experiencing issues, the unit might need a repair due to internal issues.
