Why is no sound coming from my TV or A/V receiver when I use my HDMI splitter?
Make sure your TV and/or A/V receivers are set to the proper input.
Make sure that the destination device with the lowest resolution is connected to OUT 1 port to make sure audio is heard. NOTE: The splitter uses the resolution, timing information, and audio formats of the destination device with the lowest resolution for both devices.
Make sure the TV is connected to OUT1 on the splitter, and the AVR is connected to OUT2.
Make sure that your DVD movie is original, as HDMI includes HDCP copy protection, which prevents playback of illegally copied movies.
Make sure that the HDMI cables are not broken and are securely connected.
Make sure that the audio and video formats of the content being used (i.e., Blu-ray disc) are supported by all connected devices.
Make sure that you are using high-speed HDMI cables for all connections.
Unplug the HDMI splitters AC power adapter, then plug it back in again.
Make sure the TV and the sources are set for HDMI and not DVI.
If you are connected to an A/V receiver, try changing the ports the cables are plugged into.
