    Good Day to all mac users

    my audio doesnt work. the volume option on the top right is grayed out. if i click it, i cant unmute it. if i press the increase or decrease volume, doesnt work either. i dont know what i have done to get this problem. as i remembered, i only updated my bittorent and cleanapp applications. after that, i just noticed that the volume is now on mute.

    Here are the t/s i have done.

    (i havent tried to unplug the battery yet)
    2.force shutdown
    3.smc and pram reset permissions
    5.went to sound in system pref, output volume is set to "built-in" which is correct, but volume adjuster grayed out as well.
    6.didn't turn on laptop for a day

    Hope i can get a solution.

    something strange happened btw. i slept overnight, and turned on the laptop when i got up. the audio was still grayed out. but when i checked software updates, the audio came back. i tried to play a music and it did. but whats strange is that, you can see the volume option on the right side change how many bars it has. it was 3am that time and decrease the volume to only 2bars, while the music was playing, you can see the volume option gaining volume bars but the music stops for a while. it will go back to 2 bars and the music continued. then suddenly the volume option grayed out again. i installed the updates but volume is still on mute. :(
