Question:

Why am I not getting any sound when connecting my Samsung TV to a video source using HDMI?

Answer:

To fix this issue, ensure that the audio output of your video source (DVD player, home theater system, set top box, etc.) connected via HDMI is set to PCM audio. If it is set to Bitstream or Dolby, no sound will come out. Refer to your audio source's user manual for guidance on changing the audio output setting to PCM audio.
