The audio of the video playback is muted. when i want to watch a program on the system, the speakers do not emit anything meanwhile when it is just an audio play back everything seems ok. what can i do. no upgrade had been done just the usual update on the whole system.

Try using Recovery Manager to reinstall the IDT HD Audio Driver ( this will also reinstall the Beats Audio interface ) - the procedure for using recovery manager to reinstall Software and Drivers is detailed in the document on the link below.
After the reinstallation has completed, restart the notebook.
