Hello! I have recently purchased a 32" Toshiba TV with fire tv. The model number is 32LF221C21. This model comes with internal audio (as all televisions should) however, for some reason when I first started using it I immediately noticed there was no audio. After searching in the settings (settings>display&audio>audio output) i noticed the options for TV speakers was grayed out and stuck as being turned off. Is there any reason this is happening? My sound settings in the pervious tab are also grayed out. As this is a new television, and as stated before has internal speakers, im confused as to why this would be happening.
