Welcome to the Apple Community.
Have you tried adjusting the “Audio Mode" and the “Surround Sound" settings in settings > audio and video? It may be worth trying several combinations of these settings, although typically it is the “Surround Sound" setting that causes most problems for users.
If you are using a sound system/receiver, make sure that you have correctly mapped the input port on your sound system to the output, if you are unsure about how to do this, refer to the manual that came with your sound system.
