No sound through speakers or headphones

The sound on my Macbook pro isn't working. It won't play any audio through my speakers or headphones. Before the volume symbol in the menu bar turned to a grey color, when I would change the volume using the keys on my keyboard, I would see it change on my screen and hear a sound, but it wouldn't change in the menu bar. This isn't the first time this has happened either, but the last time it was just my headphones; I was still able to listen through my speakers. The last time when my headphone jack wasn't working, I saw a red light on inside when I wouldn't have headphones plugged in. Does anyone know how to fix my current lack of audio problem and what the red light meant before?

Hi there sb757010,

No sound through speakers or headphones in 3rd Gen iPod touch

Sound worked perfectly on the iPod until it was plugged into a speaker set through the headphone jack. Ever since then the ipod gets really warm and whenever a sound should be heard, there's a faint sound kind of like white noise. When you try to play something through the music app, the play button changes to a pause button and you hear the white noise, but the scrubbing bar doesn't change position, then the pause button changes back to play after a few seconds. The iPod is also slow in every app now, and it gets really warm at the bottom when it's charging or when it's being used. The iPod is no longer under warrenty and I've tried restarting, soft and hard resets, and restoring but nothing has changed. Is there anything else I can do? Or does anyone know if this is a common problem with this iPod?

If you restored to factory defaults/new iPod that indicates a hardware problem. I would make an appointment at the Genius Bar of an Apple store and hear what they have to say. It is free.

New headset, but certain programs are transmitting sound through speakers and not headphones.

Spoiler (Highlight to read)
Hello,
Hello,
I just recently purchased a new headset for gaming but have been having some issues with it and the system sound. One major issue is when I call someone on skype, the sound from Skype or the call will go through the headphones, but any other audio comes out of the speakers. I have also notices that iTunes also does not function when I am in a call as well. Some examples would be if I were to want to watch a YouTube video while in a call, the sound would come through the speakers and not the headphones. However, I did find a fix for it. All I had to do was disable the main speakers and the audio was transmitted to the headphones. Another example would be if I wanted to run games via Steam (Garry's Mod, TF2, ect.), I wouldn't get any sound whatsoever from the game. Not through my speakers or headphones. With one exception, Garry's Mod volume I can hear through the speakers while in a Skype call, but I want the sound to come through the headphones. But with TF2, I get no sound whatsoever. If you need any more information about my issue, please feel free to ask. Thank you.

Hello @LayneStaley,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I have read your post on how certain programs are transmitting sound through speakers and not the headphones, and I would be happy to assist you in this matter!
To ensure that your headphones are utilized when plugged into your notebook, I recommend following the steps below:
1. Click the Start button
2. Click Control Panel
3. Click on Hardware and Sound (sorting the control panel icons by "category"), and then click on Sound
4. Under Playback, you should see one or two speaker icons. One of them should already have a green checkmark next to it (which will be your notebook's main speakers). If the second Speakers icon is not visible, right-click in the list of devices and select Show Disabled Devices
5. A second, disabled icon of "speakers" should appear. Right-click this icon and click Enable
6. Select the newly enabled speaker device, right-click it, and select "Set as Default Device".
7. Click Apply.
Please re-post with the results of your troubleshooting, and I look forward to your reply!

No sound from speakers or headphones on my hp pavilion dv6-6c50us

no sound from speakers or headphones on my hp pavilion dv6-6c50us. Speakers are not muted and volume is up. May have happened after a system update

Hi,
Try the following.
Download the relevant IDT Audio installer on the links below and save it to your Downloads folder.
IDT Audio Installer - Windows 7.
IDT Audio Installer - Windows 8.
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

I cannot hear sound through my iMac Headphone port,

I cannot hear sound through my iMac Headphone port, this is a very new computer. I can hear sound through the usb port of the device. How can this be fixed? Headphones are selected as an Output device.
Please help in any way possible, it is becoming quite a concern as it was just working a matter of hours ago.

usb does not carry audio at all it's a serial digital bus
things one connect to usb which play audio act the role of being usb audio cards only 1 audio card can be active at the time so if you connect an usb audio card the internal audio card is muted
this cause your headset to be muted
disconnect the usb audio card and you will be able to use your headset
if you wish to use a headset an an usb audio card at the same time the headset needs to be connected to the usb audio card

Sound through speakers & headphones with Mac Pro & Vista?

Hi,
Not sure where to post this but here goes:
I have a current model Mac pro and a set of Harmon Kardon soundsticks plugged in. All is well in OS X but when in Vista i can't get sound just through the headphones? It comes through both the headphones & speakers at the same time.
How can i get round this?
Thanks.

I am having the same issue. Did you ever find a resolution? Sound worked for me for about a month, then it just stopped working one day. I have tried driver un-installation/installation/updates with Winders XP and Vista, resetting PRAM, etc... nothing works.
Is there a good USB/Firewire sound device that would work for the MacPro running Winders?
Thanks,
B

Skype sound coming through speakers not headphones

Recently i got my hard drive changed, and since then skype sounds have not been coming through my headphones. people can hear me i just cant hear them as well. Its annoying since everything was working before. And the sound of youtube videos comes through fine.
so im not sure what it is.
Anyone help? Thanks

This is really a horrible bug, because it inappropriately routes sound through the speakers that isn't even related to Skype. For example, I am listening to a radio stream and, when I receive a Skype message, that audio blasts through the speakers.
I can't imagine why Skype would design its software this way on purpose, nor why I would be required to change ANY setting in Skype to fix something that Skype broke.

Can't play sounds through speakers but only through earphones

I got my new iPad2 yesterday and for a while I was able to play sounds through the speakers. Today speaker did not work anymore and I suspect it is related to the upgrade to the new iOS 4.3.3 that I did just before putting it to sleep. Can anybody help?

Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound. Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and its the icon; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Sound through speaker and headphones

The sound from my Nano 5th generation comes through the speakers and headphones simultaneously. I have tried 3 sets of headphones
and the plug goes fully into the socket atr the base of the Nano.
This happened initially over 11 months ago and seem to rectify itself, but now it's back. Any thoughts about how I can resolve this.
Thank you.

A reset should fix it:
Double click the Home button. Slide up with one finger on ALL your apps to close them.
Then, Press the Sleep/Wake button + Home button and hold 15 seconds or until you see the Apple logo.
This will reset your device without erasing data, apps or settings.

E93z All in One I want Audio playback through speakers and headphones at the same time

Hi there,
As the subject line reads I am hoping to enable playback through both the headphone and internal speakers on the E93z All in One unit I have.
Is there is currently a way to do this with the Lenovo HD Audio software for the Realtek system? It detects the headphones and does the typical shut off of the internal speakers however no option to enable playback through both seems to exist.
Running Windows 7 Pro 32 bit.
I cannot enable stereo mix (by right clicking in the playback area of the sound settings in Windows) to try and come up with a work around.
I have tried re-installing the drivers and not luck with more options to do this.
I have tried un-installing the Lenovo HD audio software and still no luck using the vanilla Windows 7 software.
Any suggestions would be greatly appreciated.

Well basically I want to hook in some external speakers via the headphones jack and the more speakers the better, I just figure if there's a way to have 4 speakers instead of just two it'd be cool, why let the internal speakers go to waste?
Do you know if plugging in headphones physically cuts off the internal speakers or if it's a software/driver thing?
Thanks to all who've replied
I'm pretty sure it's all in the OS, since the level control is right at the top. You can actually customize sound profiles individually for headphones or the built-in speaker, or any other sound devices. You can also use Bluetooth headphones (or a headset) or USB output devices. As far as I know, only one can be selected (in System Preferences) even if multiple ones are plugged in.

No sound from HP G62 laptop and can no longer get sound from speakers or headphone jack . USB sworks

have an HP G62 laptop. I can no longer receive sound from speakers or from headphone jack. If I plug speakers into usb - I will get sound. Any ideas?

I don't think I have anything to offer that you haven't done. In Device Manager, Device status says "working properly" and you've reinstalled this driver.
Realtek Audio Driver for Windows XP
Right?
The only other thing I know to do is restore the hard drive to its original factory fresh contents.

IPhone 4S loss of sound through speakers

Here's an oldie with a twist! My iPhone 4S has lost sound through the speakers. Strangely 90% of the time keyboard clicks work when entering the pass key but nothing after that. I have 'restored' it, cleaned every orifice and 'upgraded' to IOS7. Has anyone got the same problem but more importantly an answer.
Thanks

Thank you. Trouble is, you clearly live in Apple Land! Across the Pond it's not quite so easy!
I'll make enquiries as to wether we have such Bars.
Thanks again

Hp pavilion g6 notebook PC. No sound from speakers or headphones

Hi, I just did all the recommended updates for my computer this week due to it working so slowly. It started working like new again with one problem, I now have absolutely no sound. A big problem for me since I use this laptop as a TV and love listening to my music. Product number: LW354UA#ABA. Serial number: [edited Serial Number by Moderator]. I hope this is enough information to get help.
