External speakers suddenly stop working

My 13" aluminum MacBook's internal speakers are working fine. External speakers and headphones were also working fine until yesterday. Now, external speakers do not work with my MacBook at all, and with headphones I get a very muddled, echoy sound. This happened overnight - my laptop was just sitting, not plugged in, on my desk. I've tried restarting and resetting the NVRAM - no help.
I have a 13" Aluminum Unibody MacBook running OSX 10.7.5.
Please help!

>I had a quick look this morning and sure enough, a YouTube clip was playing, but no sound.
This happened to me too using an Tecra A11 unit.
The Youtube clip had no sound but if I plugged and re-plugged the headphone jack, the sound appeared again.
I thought this was a problem with headphone jack but I wanted to check if this issue could be solved by driver reinstallation.
Firstly I uninstalled the Realtek sound driver from the system. Then I entered the device manager and deleted the High definition Audio Controller from the System Devices area.
In Audio , video and games controller I deleted the Intel display audio entry.
Finally I rebooted the system.
After new reboot the Windows recognized the deleted devices. I checked the playback tab in control panel -> sound and found new device Headphones which was not visible before.
Then I started Youtube and checked the sound. It was available. Then I installed the newest version of Realtek HD audio driver and rebooted the unit.
The sound was still there
So hopefully it was just and driver issue

External Speakers Randomly Stop Working until I "Test" or Disable/Enable

I'm using a HP Pavillion DV6 Notebook PC Running Windows 7 Professional 64-bit SP1.
External speakers randomly stop working until I "test" or disable/enable them. Headphone/HDMI Audio Works.
Background
-Recently had to do a clean install of windows.
-Went to the HP Drivers Website and downloaded all of the latest drivers.
-I installed several other programs as well (Flash, Steam, Media Player, Browser)
-The problem started
Current Settings
-My deafult device is "Speakers and Headphones: IDT High Definition Audio CODEC"
-Enhancements are disabled
-Bass and Treble are set to 4
-Format is set to 16 bit, 48000 Hz (DVD Quality)
-Allowing applications to take exclusive control of the device or not doesn't make a difference (but it's currently off)
Troubleshooting
-The audio works by plugging in headphones or using an HDMI device
-The audio comes back if I go to my sound settings and hit "Test", or if I disable and re-enable the device
Error Messages
-Youtube starts the video for 3 seconds, restarts and sputters a bit, and then says that there was an error
-My media player (MusicBee) gives me this message: "Unable to start playback (Error = BASS_ERROR_BUFLOST)"
That's everything I can think of. Any ideas?

Hi TheBigBoy,

I see that you are having a frustrating time with the sound to your external speakers. Have you tried connecting the speakers to another computer to see if is a hardware issue with the speakers? Do the regular speakers work? What is your product number as there are several models in the dv6 series?

My external speakers have stopped working. A circle with a line through it shows up when I try to adjust the volume. I have been in system prefrences to check all the sound settings and everything is set properly. What do I need to do to fix this. Help!

Though I have doubts for success, you might try a SMC reset. It can do no harm. Otherwise, barring suggestions from others, the Apple Store or qualified repair facility is the last option.

Speakers suddenly stopped working

my sounds suddenly stopped working. After talking to a couple of knowledgeable people, I uninstalled the Realteck audio driver, and then I had decent sound coming through the speakers ! This is for an HP desktop, a6750y
So then I tried to re-install the driver. Although the driver had the same file name, it was newer than the one previously on the system, so I re-installed it, and once again, no sound. So I uninstalled this version, but now I have no sound !!!!
I do get sound through the headphones.
here's what I installed, but it's not working.
This question was solved.

William, welcome to the forum.
Have you checked in "Control Panel / Sound" to assure that your sound device is selected as the default? I have had this happen to me many times over the years; especially, if I have made changes of any kind to my computer.

Two keys on external keyboard suddenly stop working, cannot log in

I have an iMac with Snow Leopard, USB keyboard (not wireless). From one moment to the next the "a" and "s" keys suddenly stopped working. I checked in the Universal Access and Speech panes as others with similar problems were advised and this was not the problem. I tried restarting the computer to see if that would help but it did not, and now I can't log in because these letters are in my password. HELP!!!!

Try another USB keyboard. (most any brand will work)
Personally I use Logitech MK120 - USB Keyboard & Mouse Combo's with all my Mac's.

Satellite L650 - Speakers suddenly stop working

Suddenly my laptop speakers stop working. Volume was 60 % not too loud.
All drivers are ok and updated and laptop purchased 1 month ago new

Hi buddy,
Can you notice the same behaviour if you connect external speakers or headphones? Maybe its just a wrong sound setting and with external devices you can test this.
Have also a look on Windows sound settings. You can change the balance between right and left speaker.
If its really a hardware malfunction you can contact an authorized service provider. The guys will repair your notebook under warranty (free).

Help - speakers suddenly stopped working

Hi,
I was playing a CD in iTunes today, at first I was listening with the internal speakers, then plugged in some external speakers (I did not stop the CD playing), and powered them on. When the CD came to the end I unplugged the external speakers. Since then I've not been getting any sound from my eMac's (800MHz w/ superdrive, OS 10.2.8) internal speakers - they've always worked well up until now. Sound is coming through fine on headphones and the external speakers.
I noticed that I had not switched off the power to the external speakers before I unplugged them, could this have caused some problem?
I've checked the sound preferences for 'Output' and it says 'Built-in Audio Controller' - there's no other option when headphones/external speakers are unplugged.
I've restarted the machine - just in case - but no joy.
Could this be a driver or firmware (or whatever it's called) problem? It seems strange that both left and right have gone at the same time, and that there's no noise/hiss coming from them, just silence.
Any help would be most welcome.
Cheers,
Tracy

Well, I still don't know what the problem was, but when I switched the eMac on today the internal speakers are working again.
If anyone does know a reason, I would be interested to know in case its something I need to fix now, rather than leaving it to fester.
Cheers, Tracy

My external display suddenly stopped working...help?!?

I have a 2009 MBP that I have been using in clamshell mode for the past 1.5 yrs. I've had it hooked up to a LG Flatron M2362D 23" HD monitor for about 6 months or so. I have never even had a hiccup until now. However, about 30 mins ago, my display decided to stop working. I have it hooked up with the mini-DVI. I tried switching to my 19" Dell monitor (which I know works) to check and see if it was just my display, however the problem persists. Is anyone else having this problem? Does anyone know how to fix it?

I wish I could help, but I'm here because I just began having the same problem. Everything worked great until a few days ago. The external monitor works great with my old Dell laptop, just not with my Macbook Pro. This is really frustrating.

Bose speakers suddenly stop working

It's been working since I connect the speaker almost for a year I accidentally pull it out when I was taking out my usb cable when I plug it in the speakers are not working anymore.

Perhaps you accidentally plugged it back into the Audio Input instead of the Output Port?

Speakers suddenly stop working. Icon greyed out?!

Hi all.
I started my laptop this morning to find that the speakers don't appear to be working. For no reason whatsoever. They were working last night. And now they're not.
I press the volume up, down and mute buttons and it does nothing. The 'overlay' comes onto the screen showing like it has max volume, but with a circle/cross underneath (imagine a no smoking sign).
In the top menu bar, the sound icon is there but it's greyed out so I can't do anything.
Anybody help me please?!?

the same thing happened to me. I closed my laptop to take it upstairs to work some more and when I opened back up the sound icon was greyed out. I tried plugging in speakers and a headset and they work fine. I think that it is probably the logic board but I read here : http://discussions.info.apple.com/thread.jspa?threadID=2244270 that it could just be the internal switch. I have a late 2008 model and the post seemed to mention models of that date. Let me know if you figure this out.

External monitor suddenly stopped working at 2440x1440 on OS Lion 10.7.3

Hi,
I have a 27" iMac and I'm using Samsung SyncMaster SA850 as a second monitor (connected via a displayPort cable with a mini DisplayPort adapter).
Everything worked fine until yesterday - the Samsung screen turned black and now it only works with max resolution 1280 x 1024 (native is 2440x1440). I think I upgraded Lion 10.7.2 to 10.7.3 (I don't remember for sure though).
When I connect the monitor to an iMac with 10.7.2 everything works fine. And another iMac with 10.7.3 has the same problem as me.
Any ideas what could be wrong, please?
Thanks!
Tomas

It's very temperamental i find. I have just moved house and when i reconnected everyting i couldn't get the monitor to work properly. I played around for a while and eventually changed my input from DVI1 to DVI2, then played with the input button at the bototm of the screen (the one just on left of the power button) and somehow it just seemed to click into place... Frustrating i realise, but now that it's up and running it looks great and, I daresay, looks much better than the 27" thunderbold display in my opinion... primarily because the non-reflective surface is great, but also because it is so easily height adjustable, a feature which unfortunately is non existent on the mac monitor.
good luck anyway...

Internal speakers have stopped working (Lenovo W500 with Win 7 Pro)

Hi
I have a Lenovo W500 4062-5YG... O/S: Win 7 Pro
My sound device is a Conexant 20561 SmartAudio HD.
The problem is, that the internal speakers have stopped working all of a sudden... I think it is a hardware problem since when I hookup external speakers or headphones they produce sound... but I am no expert!
I have done the following to try and fix it:
Disable, then enable audio drivers
Uinstall, then install audio drivers
Setting the internal speakers as the default speaker source
Restoring the system to an earlier day (where I knew that the speakers had functioned)
None of these actions have worked.
I actually thought I could perform a hardware test on the speakers in the "Lenovo Solution Center"... but it doesn't seem like it:-(
So...
How can I know for sure whether it is a hardware or software problem?
And more importantly - How can I get my internal speakers to work?
Any help is appreciated.
Cheers
Philip

Pavillion Laptop with Windows 7 - Speakers have stopped working but headphones do!

Hello
I have a Pavilion dv6 Notebook, with an AMD A8-3500M APU and Radeon HD Graphics card. It is a Windows 7 64 bit system and was purchased in october of 2011
The speakers on my laptop have suddenly stopped working, but external speakers continue to function. I have tried the windows troubleshooter, resetting defaults on playback devices, and updating drivers both through the device manager and through HP Recovery manager. I have tried uninstalling and re-installing drivers, and a hard reset ofthe computer (unplugging all devices and power sources, waiting and restarting). I have tried System Restore to restore the system to a date before the problem. None of these have helped. Anyone have any ideas?

Hi there @Rob5
Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.
I understand that you are having problems with the notebook speakers., and I am happy to help with this. From all the trouble shooting you have described it sounds like it may be that the speakers themselves may have gone bad, or the connection is loose.
Before we look at the possible physical problem, take a look through this page first, just in case there is something you have not yet tried.
No Sound from the Speakers (Windows 7)
If you are still getting now sound, then take a look through page 62 of 137 in this guide:
HP Pavilion dv6 Entertainment PC - Maintenance and Service Guide
That page shows how to replace the speaker assembly and the relevant part number, but before going that route, I would suggest just disconnecting and reconnecting the speakers, in case it is just a bad connection. Over time a connector can work itself loose. Just doing that may fix the problem. If not then you can call our technical support at 800-474-6836.

HP Pavilion dm1-4000au Entertainment Notebook PC_Keyboard and Touchpad Suddenly Stops Working

Hi there,
I have an HP Pavilion dm1-4000au Entertainment Notebook PC (QG411PA) running Windows 7 Ultimate 32-bit for more than a couple of years already. During those times up until now, whenever my laptop is on standby for an hour or so, its keyboard and touchpad suddenly stops working, regardless if its running on battery or on AC power.
I always ensure that I have an external mouse in order for me to navigate properly and pull up the on-screen keyboard in order to type once that issue arises.
All appears to be updated in terms of Windows Updates and I even reformatted it, but issue still persists.
Is this particular issue that I am experiencing a harware issue? Perhaps a software issue? Or maybe a defective model itself?
Your prompt response is highly appreciated.
Sincerely,
Led

Outputs Suddenly Stopped Working.

I have a 5th gen Ipod that I've taken very good care of. Until yesterday I've had no problems with it at all. I was using the Ipod in my car w/ my Itrip and the Audio suddenly stopped working. I assumed it was the Itrip not working correctly, so I plugged it into a set of speakers (via the bottom output) but that wasn't working either. Then I plugged headphones in and there is no audio feeding through the headphone output either. I can see on the screen that the songs are playing on the ipod, but apparently the outputs are not functioning correctly. I tried all of the "Rs" recommended in troubleshooting but those did not help. Any suggestions?

i have the exact same problem. Although i am able to here the clicks throught the headphones which makes me wonder that this is something with software. although i have restored and reinstalled and all that, nothing.
Anyone have a solution?
