Very low sound upon playing 1080p movies

hi guys,

I'm newbie here.I'm having a problem.
When I'm trying to play 1080p movies (size: is around 2 gb, format .mp4) on my samsung led tv (1080p full hd), the audio is very low.
But when the same file is played on laptop, the audio is normal.


Anyone having/faced same problem?
