Sound troubleshooting - is it the panel?

Sometimes the sound from a computer application is muted, volume levels on the computer are low, volume on the computer is not assigned to the LED panel, or a cable is unplugged.  There are a myriad of things that may cause someone to report "No Sound or Sound too low."
 
The first thing you want to try is powering the panel off by flipping the rocker switch on the back of the panel (Lower right corner). Wait for it to completely shut off then flip the rocker switch back on. Then test the sound to see if it is working.   

Here's a quick and easy test to determine, or eliminate, that the problem is an internal defect with the panel.  Try playing an audio file while on the Android OS (HomeScreen).  You will need a USB stick with an audio file (song or video) on it.  

Testing Sound
  1. Power the panel up.
  2. Select the HOME button.
  3. Insert USB (with an .mp3 audio file) into one of the 2 front USB ports of the panel. 
  4. When the USB Dialog box appears, go to the APPs, click on "ES File Explorer" > Select the USB > Select the Audio File > Select ES Media Player.
  5. Play the file and manipulate the volume from the remote control, the panel buttons or the screen.  If the volume seems a little low or muffled, check to be sure the panel is in STANDARD sound mode.
Troubleshooting Sound
  1. If it plays with audio, then the panel's sound is okay and troubleshooting from the computer or input will be needed next to identify the culprit.
  2.  If your computer is connected to the panel via VGA: Ensure the audio pigtail is plugged into your computer audio port> also double check that it's plugged into the VGA audio port of the panel's VGA input.
  3.  Ensure that the sound settings on your computer are set to output to the LED panel.
  4.  If you are playing audio/video through a web-based platform (i.e. YouTube), ensure that the sound setting inside the program is not Muted.
