piprumsey , your player is an Action-based chipset player with firmware v9.0.50.

Regarding the music, try another set of earphones, also try applying slight pressure all around to the plug when it is connected in the socket.
I have a feeling that there is some contact/soldering problem.

Also, it does not play .mp4 format files. To play videos, you'll need to convert them to .AMV format.
They just call this mp4 player probably to sell them better.
