Question about Apple MacBook Air

1 Answer

My internal Speakers are muted and when I go into System Preferences the mute button is check but it is grey, so it will not allow me to uncheck. In the sound folder it simply says "no output devices found". It seemed to fix itself yesterday but then the problem came back. Related is that when using Skype (text messaging only because no sound) if I click on call or video the program just crashes...when I restart the chat page is just open where I left off... but anytime I click to video or call the program just closes again......can someone help? I am wondering if I have accidentally pressed an external over-ride key on the keyboard or something similar ... help please

Your keyboard top case is fu.ked. Replace the top case keyboard and your sound will come back.
Have the Apple dorks do it if your still under the 1 year standard warranty or 3 years if you bought the extended warranty.

No sound device in macbook air


Apple menu (top left) System Preferences > Sound > Output tab select the Internal Speakers
check your output volume and make sure the Mute checkbox is unchecked.
Plugin a pair of headphones. If you still have no sound. The sound board needs to be replaced, which is attached to the logic board. Meaning the whole logic board needs to be replaced.

Sound wont go on. muted but i have no way of unchecking the mute box


Go to the top of your keyboard. There is a button with a black sideways bell shape icon on it ( a speaker) (the f3 key)...probably four in from the left starting with esc. Toggle that on. It may be on the mute setting now. It should have waves coming out of it when it is unmuted. To the right of that button (two buttons to the right) is the increase volume control button, the (f5) key. Make sure the volume is up! If it is down all the way you will hear nothing and it will be also muted.
I am not sure why if you go into System Preferences (under the Apple icon) and scroll down to Sound and Output, the mute box cannot be unchecked. Perhaps using the function keys to unmute and increase volume on the top of the keyboard will help.

Hope this helps

I can't hear any audio at all on my Powerbook g4 laptop. the mute button is on in the preferences yet grayed out. no speakers, internal or otherwise, are in the list.


Which version of the Mac OS?
You will need a sound output selected to be able to unmute the sound. Internal Speakers, Build-In Output should show in System Preferences :: Sound. You may have to "archive and reinstall" to get the sound driver, if say deleted or moved. If you can make an appointment at the Genius Bar of the nearest Apple Store. -Ken

Hp dv71245dx cannot remove from muted state.


hi
Go to Control panel > Sounds and Audio Devices > Volume. Check that Device Volume is at least halfway across the slider and that Mute is unchecked. Go to Advanced and make sure that nothing is mute. Go to Speaker Volume and set the sliders at least halfway across the slider. Go to Advanced, and in Speakers setup choose Laptop Stereo Speakers (if that's what you have). Go to Performance and choose Restore Defaults. Click Apply > OK

plz do inform if this has sorted out the problem
all the best
regards
