My sound/speakers recently stopped working.

I took in my macbook pro for a genius meeting and the man downloaded some software update and my speakers started working again, now they just stopped working for the second time. That's all i know. Can someone help?

Hello there, yousefghabour,
A great Knowledge base article for troubleshooting sound on your Macbook Pro would be the following:
Troubleshooting issues with no audio from built-in speakers on Macs
http://support.apple.com/kb/TS1574
Since you've likely done all software updates at the Genius Bar, then the following from that article should be helpful:
Check your Sound System Preferences pane
If you are still having issues after you have confirmed the proper version of Mac OS X is installed, make sure the computer is set to play sound from the right source.
Remove any external audio devices and cables from the USB, FireWire, or 3.5 mm audio ports.
Open System Preferences from the Apple () menu, the Dock, or from the Applications folder on your hard drive.
Open the Sound pane and the Output tab, then select Internal Speakers as in this image:
If Internal Speakers is not an option proceed to step 4. For Mac Pro computers, proceed to step 5.
If Internal Speakers is present but not selected, select it and test again.
If the Output volume slider is low or the Mute box is selected, raise the volume slider or deselect the Mute box and test again.
If the issue continues through these steps and Internal Speakers remains the selected option proceed to step 5.
If the Internal Speakers option does not appear in the Output tab and your computer is not a Mac Pro, check that Digital Out is present as in the image below:
Confirm again that all external audio devices and cables have been removed.
Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.
If you do not see a red light, proceed to step 5.
If the issues persist, contact Apple support for further troubleshooting assistance.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro D.

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.

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,
Welcome to the HP Support 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 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?

    Make sure that Mute is not enabled.
2.Plug in and remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
    Try this even if you don’t see the red light.
3. Reset PRAM. http://support.apple.com/kb/PH14222
    Do this twice

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

Hello Philip,
As mentioned in your post, you have performed all the major troubleshooting steps to resolve the issue. I suggest you to update your BIOS also in order to resolve your issue. You can download and update the BIOS update utility from the below mentioned web link.
http://support.lenovo.com/en_SG/downloads/default.page?
Kindly click on Quick path and put your 7 Digit TYPE-Model number(40625YG) in the box and then click on the Find My Product. Please click on BIOS and then download the BIOS update utility according to your Operating System. It might resolve your issue. If it will also not work then it seem to be an issue with hardware. Kindly get in touch with the support centre they will assist you and try to resolve the issue.

[solved] Sound in flash stopped working (alsa, x86_64, rate)

Why?
Sound in flash stopped working (alsa, firefox, x86_64). Tried flashplugin-prerelease from archlinuxfr: nothing different.
Everything worked before I rebooted. I changed nothing else since last reboot. Can't figure out what happened.
Updates among other things:
firefox, xulrunner (firefox I did restart - the new one had sound in flash before I rebooted)
openal, lib32openal (don't think that has anything to do with it?)
libsndfile (that's something entirely different, too, right?)
And a lot of others that don't look related... no Idea how many really, I haven't rebooted in quite a while. Maybe there even was a kernel update since last reboot. Or two.
edit: Also some interactive flash stuff that did work before has stopped working now.
edit2: Chromium doesn't have sound in flash either. Tried recompiling firefox / switching to AUR/firefox-pgo: no change. Everywhere else, sound is working fine. Also, several flash games I tried get stuck / freeze after intro.
Thx!

Couldn't find any changes there:
I LC_ALL=C aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
I tried the multilib version and the x86_64 prerelease. Both did work perfectly fine before I rebooted (I tried which one works better recently and couldn't see any real difference). Didn't have trouble with flash for months before this reboot.
I found a few modules I was unfamilliar with were loaded:
snd_seq_os snd_seq_dummy snd_seq_midi_event snd_seq snd_seq_device
... and removed them with rmmod. No change. (I should have restarted alsa at that point I guess just to make sure, those weren't the problem?)
Then I changed the rate in asound.conf to 41000 and restarted alsa - now everything works again! Strangely, no more freezes too (those were reliable).
I remember having had problems with flash not having sound unless I set the rate to 41000 about a year ago. After some updates, I tried again and all rates supported by my sound-card seemed to work. My guess would be regression in whatever fixed that problem... but I don't know.
I'll leave that "unsolved" until I manage to figure out what it really was about.

Best.

My inernal speakers have stopped working. I now have a little 'no entry' sign.

My internal speakers have stopped working - when I click on 'sound' I get a little 'no entry' sign; I've done all the Preferences things, and looked at Help, but no result!

Realtek is default audio
Control Panel/ Sound & Audio Devices/ Audio tab/ Sound Playback click on down arrow and check that the correct audio is selected. Typically the problem will be they something like "modem line 0 playback" might have been substituted for the proper audio device.( Didn't Worked)
Chipset Utility - install ( Did'n't Worked Aswell)
Start / Control Panel / Administrative Tools / Component Services / a separate window will open in left pane click Services(Local) from the tree / Scroll down to Windows Audio service / if the service is Disabled or Manual right click > select Properties > under Startup Type change to Automatic > click Apply / click Start > OK Reboot. (Worked) But First The Quality Was Not As It Was Before And Then Sound Card Stopped Working Again.
Try a System File Check
go to Run - type "sfc /scannow" No Success.
I have installed windows again but no success. :(

How do you get your Excel Solver back? I have already tried going into add-ins. It only recently stopped working.

Yes, it indeed boggles the mind. I'm of course referring to the fact that your post concerns Verizon Wireless products and services. This forum is dedicated exclusively to Verizon Communications services. As you probably know, Verizon Wireless and Verizon Communications operate as separate companies.
If you need help for a Verizon wireless product or service, it's best to direct questions to the Verizon Wireless forums. You can reach them by clicking on "Wireless" (either here or at the top of the page).
Good luck and I sincerely hope you get your issue resolved.

Iphoto has recently stopped working; it continually shows the loading circle. I’ve uninstalled and reinstalled it, updated it

Iphoto has recently stopped working; it continually shows the loading circle. I’ve uninstalled and reinstalled it,updated it and reinstalled all my apps with the ‘applications install DVD’ however it still does not work. I have also tried holding the command and option key while pressing iphoto then when the pop up appears i press the checkboxes that have been suggested by other users however nothing happens. Any other suggestions would be great!

Ok the program itself is likely fine, it's the files it depends on that are not.
Step #1
1: Open your Users/Library/Preferences folder (if on Lion you need to use the Go in Finder)
2: Scroll down until you see a file called
com.apple.iPhoto.plist
3: Trash it and reboot, start iPhoto and see if it works.
Step #2
1: Go to your Users/Pictures/iPhoto Library and right (or hold option) click on it and "show package contents"
2: Inside will be a folder with your originals, copy them out.
3: Move and rename the iPhotoLibrary file outside of the Pictures folder.
4: Reboot and restart iPhoto, check inside the Pictures folder if iPhotoLibrary was created.
5: Download ClamXav and run a scan on the Original photo's and your whole machine too while your at it.
(it's if there is a picture in there from Windows it could contain a corruption caused by malware)
6: Reimport the originals back into iPhoto.
See if those two steps resolve your issue, if not I could suspect next a network issue? Like iPhoto is trying to contact the internet and can't or gets hung?
You can can create another user, use the Shared Drop box to transfer files and log into the other user and see if it's a issue with just your User account, and if so you might just want to transisition over and then one day delete the old user and it's problems.
Please keep your Flash updated.

My iphone5 speakers have stopped working. the headphones still work as does the ringer. the phone indicates it is still in headphone mode. does anyone know how to fix this ?

after running i disconnected my iphone headset. since then my iphone speakers have stopped working. i can still listen to music using headphones and the phone ringer still works but the speakers are silent. when i adjust the volume it indicates it is in "headphone" mode. Any idea how i can solve this problem ?

I have read in other threads with similar problems that cleaning the headphone jack/port seems to usually work. The simplest method is to rapidly plug/unplug the headphones a few times. See if that works.

HT1695 My Iphone5 has recently stopped working on wi-fi at home and bluetooth in the car. I am able to connect several other devices to my wi-fi at home and my Iphone will connect to other wi-fi alternatively to my home.

Hi
My Iphone 5 has recently stopped working on my home wi-fi and my car bluetooth. The phone will connect to other wi-fi devices but nothing on the bluetooth at all. Other devices are able to connect to the home wi-fi.
I have reset network settings and reset all settings. Still it wont connect to the home wi-fi or my car.
I have since taken my car in for it to be checked by the garage and am having the same problems in my courtesy car.
Short of throwing the phone out of the window any suggestions how I can fix it?
I'm thinking it'll have to be a factory restore

I have an hp dv6910us and the system speakers have stopped working. I cannot reinstall the driver.

I have an hp pavilion dv6910us and the speakers have stopped working and no longer show as installed as a device. I have tried reinstalling the audio device driver, but the hp website does not list a driver for my specific laptop.
Right now it shows that I have a bluetooth audio device installed. I have never installed this device and don't know where it came from.

I had the exact same problem, updating updating the Mbox 2 drivers on the Avid website has fixed the problem.
