Hi i ve a mid 2010 MacBook Pro

 

and since recently the issues amount.

I cannot hear any sound anymore and if looking into the preferences, it appears muted is ticked but i cannot untick it.

 

This applies to all internal speakers and the headphone jack while using a USB headphone works.

There is no red light in the headphone jack on so i ve no idea what to do to fix it.

 

Since i updated to lion years ago i also lost functionality of my dvd drive.

 

This is my last mac as with windows i can at least fix those issues or get inexpensive help. WIth mac it all comes for a top of the range premium.

 

Anyone able to help me to use my headphones again??

 

Thanks a million

MacBook Pro, OS X Mountain Lion (10.8.2)

    Have you tried disconnecting the USB headphones? Could be they are controlling the system for sound output to the USB port.

     

    P.S.

     

    My current MBP and iPod will be the last Apple devices I ever buy.

     

    Good Luck and Best Wishes.

    Reset SMC.     http://support.apple.com/kb/HT3964

     

    Choose the method for:

    "Resetting SMC on portables with a battery you should not remove on your own".

     

    Applications/Utilities/ Audio MIDI Setup.app

     

    Audio Devices window

    Side Bar

    Click the Built-in Output.

     

    Under Mute any box checked? If so, uncheck it.

     

    Best.

    I just had this happen out of the blue on my one month old 13" MBPRetina. I researched everything on here and the internet and then it occurred to me to try an old PC trick, which is restart the computer (I usually put it to sleep) to reload drivers and it fixed it for me...don't know if this will help anyone else but good luck.
