The picture quality is good but the TV does not produce any sound when connected to an accessory device with an HDMI to HDMI cable.
Follow these steps to check if your device is configured correctly:
- Some accessory devices have an HDMI audio output setting that needs to be turned on when using an HDMI to HDMI connection.
- Check the on-screen menu of the accessory device to ensure that the HDMI audio output is set to ON.
- In some cases, you may need to set the digital audio format of the accessory device to pulse-code modulation (PCM) mode. For detailed information, please refer to the user manual of the accessory device.
- If the TV is connected to a PC, make sure that you have installed the latest drivers for your PC's graphics card.
