Troubleshooting Samsung TV Problems
Digital Audio
*
If you have a device plugged into your digital audio output on your TV but you cannot hear any sound, it is probably due to the output being disabled. When you plug a device into any of the HDMI outputs on the TV, the set automatically disables the digital audio output. Unfortunately there is nothing you can do to change this. You will need to plug the device you were trying to plug into the digital audio output into some other kind of available output, preferably HDMI for quality reasons.
