Hello Everyone,

 

This morning there was no problem with the sound of my Macbook. But when I got back from school I opened the laptop(it wasn't even shut down) and I couldn't increase/decrease the sound anymore. There is no sound coming from the Macbook anymore and the icon on the top right corner is mat. When I try to increase/decrease the volume the icon on the below picture appears. The thing is that when I connect speakers or my headphone to Macbook the volume problem disappears and everything works just fine.

I did the PRAM reset by pressing the"command,alt.P,R" keys at the start up, although the opening sound works fine when the desktop appears there is no sound again...

Thanks in advance.

    Look in the headphone jack and see if there is a red light on, if there is try plugging and unplugging a set of headphones in and out a few times. You can also go to utilities>audio/MIDI set up click the output tab and make sure it is set to internal speakers.  Sometimes just putting it to sleep for a few minutes using the sleep command from the apple menu and waking it will restore normal function.  If the red light persists, you can try a Q tip with the end cut off and GENTLY try massaging the headphone jack, there is a micro switch that sometimes gets hung up. Stop at the slightest resistance. All the best
