Question

Why is there no sound coming from my TV or A/V receiver?

Answer

There is no sound coming from my TV or A/V receiver. 

CAUTION: Do not connect the switch box OUTPUT to a video recorder. Doing so will automatically lock up the audio transmission as required by HDCP (High Definition Content Protection).

 

  1. Make sure your TV and/or A/V receivers are set to the proper input.
  2. Make sure the TV and the sources are set for HDMI and not DVI.
  3. Make sure that the HDMI cables are not broken and are securely connected.
  4. Press and hold POWER/SELECT for 3 seconds to turn the switcher off and then turn it back on.
  5. Make sure that the audio and video formats of the content being used (i.e., Blu-ray disc) are supported by all connected devices.
  6. If you are connected to an A/V receiver, try changing the ports the cables are plugged into.
  7. Make sure that you are using high-speed HDMI cables for all connections.

The audio has some static.

  1. Make sure that you are using high-speed HDMI cables for all connections.
  2. Make sure that the TVs or A/V receivers audio resolution supports the source devices output resolution.
