no sound

Your post does not have much information to help us solve your problem.

Have you checked the volume?

Are your speakers (if any) connected to the right socket? Are they on?

Have you checked the settings in System Preferences ----> Sound -------> Output.

Might be some other application that uses or makes sound. In my case it was a conflict with SoncMood that caused no sound.

When you are in system preferences -----> Sound----> Input

Does the mic pick up an noise? Eg: If you speak or type, does the input level flicker?

What is your selected output device? (System Preferences ---> Sound ---> Output)

In System Pref ---> Sound ---> Sound effects,

Is "Play sound effects through" set to selected sound output device?

Is the alert volume max?

Is play user intergace and sound effects checked?

Also, have you recently installed any new applications since this problem started?

This doesn't do anything for me at all. Periodically when the computer wakes from sleep the sound ceases to work, no amount of juggling settings does anything at all. The microphone appears to be working, as I can see the levels responding when looking at the sound preferences.

So far the only thing that has worked in the past is to totally restart the computer. A real pain in the hiney.

I appear to turn up the sound all the way. Visually it looks as if it is working because the little icon with the speaker appears on screen and the number of squares goes up and down properly. But there is just no sound. There's no little red light in the audio jack to indicate it thinks it is still being used as a headphone jack either. Sometimes that is the case where it gets confused if you unplug headphones from the jack.

So even after turning the sound all the way 'up' and getting nothing, I restart, and when the system comes up and I can turn up the sound, it starts ALL THE WAY down at the bottom of the scale. So it's definitely getting confused about something.

I opened my music player and low and behold the sound there was muted. I unmuted and all my effects are working again

My experience is similar to terriergal. I find that when I put my iPhone 4S (running iOS 5.0.1) into silent mode using the switch on the side, whenever I turn the switch off I lose all sound. I also frequently lose sound when, instead of putting the phone into siltent mode, I turn the volume all the way down. When I turn the volume back up there is no sound. Like terriergal the only way to get the sound back is to reboot the phone.

I had this same problem, but only on one out of four users on this iMac had it, the one with administrator rights. Fortunately, the fix was simple. System Preferences --> Sound --> Click Internal Speakers. For some reason, it was set to Soundflower (2ch). Strange because I have never changed this setting, did not even know it existed. Hope it helps.

can you set my device for my sound to go on.

I have iPad2. iOS 7.0 updated.

Various sound problems.

Sometimes no sound at all, sometimes sound. Weird echo effects.

Weird noise. Extremely loud sound (even is setting shows 10% of max volume)

Tried all basic stuff: resets, mute on/off, sound sliding min to max and back.

Airplay on/off etc.

Is there some announcement fron Apple, are they aware of problems?

i have not heard anything from apple despite many folks having sound issues, same here, sounds comes and goes no rhyme or reason.

Sorry. When I've researched this before it seems to be a common problem. I thought I wouldn't need much explainning. There seems to be 1000's of people unable to get their sound back. I have had no sound for about 6 months now. It all started after I plugged in headphones. The ipad thinks thety are still there, and says headphones inserted. However after searching the internet for solutions, changing all the sound settings and reinstalling IOS several times, nothing seems to work, not even external speakers. Do you think sending it to apple UK would solve the issue, can we do such a thing anyway, is there a repair shop?
