How to fix no sound when using ARC to connect a Xiaomi TV to an amplifier?

Question

Accepted Answer

If there is no sound when using the ARC (Audio Return Channel) to connect a Xiaomi TV to an amplifier, please follow these troubleshooting steps:
1. Confirm that your amplifier supports ARC and that it is enabled; otherwise, no sound is typical.
2. Confirm that both the TV and the amplifier's HDMI ports support ARC, and that you are using the ARC port for the connection.
3. Set the TV's audio output to HDMI (ARC).
4. Avoid activating other HDMI devices during ARC initialization. If necessary, restart the TV or turn off different devices.
5. Avoid setting devices connected to HDMI 2 or HDMI 3 ports to picture-in-picture mode; it is recommended to use the HDMI 1 port.
6. Manually select the HDMI (ARC) signal source on the TV and wait for the signal to stabilize before exiting.
7. If the amplifier does not support RAW or Dolby/DTS digital decoding, you can set the TV's digital output to PCM.
8. ARC connection allows simultaneous sound output from both the TV speakers and external speakers, but compatibility cannot be guaranteed due to differences in amplifiers.
9. If the problem persists, please confirm that the amplifier is supported and correctly configured. If necessary, request an inspection from the after-sales service center.
