The Apps such as C4 or Netflix are play in a “speeded up” mode with no sound. 

How do I fix this please ?

Perform a soft reset and check if it helps.

This means, for those who don’t want to go hunting all over the web for the information, pressing and holding the On/Standby button on the remote for just over five seconds, to start this process.
