Sound suddenly stopped working.

Hi, my sound on my HP ENVY 15 Notebook PC just suddenly stopped working the other day. Everything says that it is functioning, and my drivers are up to date, but I cannot seem to get the sound to work out of my speakers or out of headphones.
Product Number: A9P60UA#ABA
Running Windows 7 Home Premium 64-bit
If you could help, that would be wonderful! Thanks!

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp56501-57000/sp56900.exe
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,download and reinstall the Chipset driver on the link below.
Chipset Driver - Windows 7.
When this has completed, shut down the notebook, unplug the AC Adapter and then hold down the Power and Beats buttons for 10 seconds. When done, reconnect 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.

DP-K

My sound suddenly stopped working, how do i fix this?

my sound suddenly stopped working after i unplugged my headphones, how do i fix this?

Common problem.
Check the headphone port - if you can see a red light, the port is still live, cutting off the internal speakers.
The cause is a little leaf switch that is pushed over by the jack when you insert it. Sometimes these stick.
Try inserting and removing a jack a few (dozen) times.
If that doesn't free it you may attempt to tease it with a slim non-conducting tool (like a toothpick). Ensure the Mac is not only shut down, but unplugged if you try this.
And be careful; the leaf is fragile and it's an expensive bit to get to and replace, in fact on some models it's directly on the logic board.

New mail sound suddenly stopped working

I assigned a 'new mail sound' (wav file) and for no apparent reason suddenly stopped working. Anyone else experienced this ?

This sometimes happens to me too, as well as my alerts with iChat. I have to restart the computer and that fixes it for me. Hope that is the case with you as well.

Sounds suddenly stop working

Certain sounds on my iPhone (text alerts, text sent sound, etc) will suddenly stop working. I will get notification of an incoming text with a sound all day long and then out of the blue there will be no sound to accompany the alerts anymore. When I send a text, I always hear a sound when it sends the text...but just like the alerts, the sound for that will suddenly quit too.
Yes, I've checked the loud/silent switch. I've checked the volume. The only thing that seems to fix this issue is powering off and back on.
I don't use headphones (I've seen this can sometimes cause the silent mode to get stuck) so that isn't the problem. I thought maybe it had something to do with the bluetooth connection in my car but the sound will quit sometimes when the bluetooth is off and I'm nowhere near my car.
I had this issue with my iPhone 4s and just put up with it until I got the new iPhone 6, figuring I wouldn't have the issue anymore with a new phone. My iPhone 6 is still doing this so I'm guessing there is some crazy, hidden setting somewhere I'm not aware of, or there is something wonky in the iOS.
This is incredibly frustrating as I have not known about an urgent message because the phone didn't make any alert sound to let me know I received a message.

Was wondering if you had found a solution for this? I went to the Genius Bar 3 seperate times to get this exact issue resolved. First they reset my phone as a new phone, then they replaced my speaker, and finally they replaced my phone. Still, with a brand new phone, it is happening. I have iphones for a long time and do not believe I am doing anything differently. Have you found something that worked for you? Thanks!

Sound suddenly stops working (Youtube)

Hi!
Since I installed a Flash Player update 1-2 months ago, the sound in almost half of the videos I watch on Youtube suddenly stops working (usually only in videos that are longer than 10 minutes). First there's a short crackling sound (not all the time, though) and then the sound simply stops, even though the video is still playing. Reloading the page or jumping ahead a few minutes, then going back to the original spot usually only fixes it for less than 5 minutes and if I do that 2 or 3 times, the sound won't even be there for more than a few seconds. Restarting Firefox doesn't help, either. If I want to try again with the same video a few days later, the problem occurs again.
I'm using headphones (Sennheiser HD 201) that are plugged into speakers (Logitech X-140) but I'm 100% sure that those aren't the culprits since I can listen to mp3s, watch videos (avi, mp4, doesn't matter) or play games just fine and the problem has never ever occured while doing that. So it definately has something to do with the update 1-2 months ago and the latest update (maybe a week ago) didn't fix it. I also already saw a few comments on videos I'm experiencing the problem with about the sound suddenly stopping.
OS: Windows 7 (64 bit)
Browser: Firefox (36.0.4) - also tried loading the video in IE11 but all the buttons (quaility settings,...) were missing, so I closed it again.
Flash Player: 17.0.0.134
Any idea how I can fix the problem and if there's already a fix in the works?

Most of the videos on YouTube these days are HTML5. If you right-click on the problem video, are you getting About Flash Player, or About HTML5?
If it *is* Flash, do you have the same problem if you disable Hardware Acceleration? See the section on it in the troubleshooting guide below:

My iPhone sound suddenly stopped working.

I have had my iPhone 4s for over a year with no problems other than the occasional slow down, etc. Just last night, the sound on my phone randomly stopped working. It will work for a few seconds then stop, and just keep doing it. Its my ringtone, text tone, keypad tone, music, and video apps. I've tried turning the phone on and off with no luck. I just want to know why my phone has suddenly started doing this when it was just working fine and how to fix it. Please help?

None of these methods worked, so I just took a very thin paintbrush and dampened it using a Clorox wipe. Then, I just wiggled it around in the charging port. The sound worked for like 3 seconds then it stopped again. So I continued to clean it and it worked! After I listened to my music for about 30 minutes until it stopped again. I just blew hard into the port and it started working again. I think the problem was that the phone thought it was docked into speakers because it was so dirty. I think I'm going to get an Otterbox so this doesn't happen again. I hope I helped.

How do I resolve sound issues? I have gone to settings but I have not made any changes but some sounds suddenly stopped working like keyboard clicks etc.

I haven't made changes to my sound settings but suddenly now certain sounds do not work such when I plug up to change, keyboard clicks on messages, etc

Double-click the Home button and swipe Task Bar to the right. Check volume and mute settings.

Sound suddenly stopped working for HP Pavilion HPE h8xt

It was working perfectly fine a few weeks ago; then last week it stopped working and I haven't gotten it to play any sound since. I'm using my old Emachines SP-20A speakers. I tried my headphones to make sure it wasn't a speaker problem, but no sound from there either. I didn't make any changes I can think of.
I have already tried everything on this list, to no avail: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01884922&tmp_track_link=ot_faqs/top_issues/en_u...
There are no error messages, nothing. Everything seems to be fine, but...
I have a HP Pavilion HPE h8-1070t CTO Desktop PC and am running Windows 7 64-bit.
I'm really at a loss here and I can't work without sound. Help would be very much appreciated!

Hi,
It would be helpful if you posted the exact HP product number.
Think back to when your PC operated correctly and then when the sound failed. Between those times, what changes or updates were made to your PC?
You might look in the Control Panel --> Programs and features and look at the changes about the time when your sound failed. In that same Control Panel --> Programs and features you can also look at installed updates and dates.
Your PC is still under warranty so you might give HP Support a try. You already probably know what they are going to tell you.
HP's support number is 800-474-6836 or 800-HPINVENT or online here.

Hey, my sound suddenly stopped working! Please help me :)

Hey guys, suddendly my sound stopped working this morning why is that? I really need to fix this soon, so if you have any ideas it would really be usefull. Thanks

Don't restore just yet - your music might still be there. There are several threads addressing this in the iTunes board under Discussions. I'll look around and see if I can find something for you on how to access your ipos as a hard drive - which will allow you to see if the songs are there. IF THEY ARE you can do the following:

Back in a bit if I can find the thread explaining the above-mentioned process (unless someone else beats me to it).

[solved?!] Sound suddenly stopped working (arch in vbox vm)

Hi all,
I installed arch-i686 in a VirtualBox virtual machine a few days ago and at first, everything worked well, including audio. The guest additions are of course installed and running.
After making some updates with "pacman -Syu" the sound stopped working. There is no error message when I start e.g. vlc from a console and let it play an mp3-file. But there is no sound at all.
I already increased the volume of all the channels in kmix and alsamixer without success.
Can someone give me a hint?
Thanks in advance & kind regards,
jamesbond007.

Well, after a reboot of the host (not guest) os it now continues to work!
I don't understand why, but I'm happy about it nevertheless.

Sound suddenly stopped working after reboot

I just got KDEmod installed and working. Sound was working in it before I rebooted, to get ntfs-3g and hal working so I could mount my Win7 partition. When I got back into KDE, I was notified that "The audio playback device *** does not work. Falling back to ." I googled around all day, but couldn't find the cure for this. Before the reboot, I installed hal and dbus through pacman, and added them to my DAEMONS=
I'm thinking it has something to do with hal or dbus somehow, is there anyway I can undo what I did? Or is there anyone else who had/is having this problem that could help?

Same issue here after upgrading from KDE 4.2 to KDE 4.3.
Whenever a system sound has to be played, I have this notification:
"The audio playback device does not work Intel ICH6 with STAC9750,51 (Intel ICH6). Falling back to default."
Then it does fall back to default device and correctly plays the sound.
However, when I run JuK, after displaying this same notification, I have no sound, or rather, I rarely have sound (sometimes it takes a couple of seconds to start to play, more often it does not start at all).
I don't know if it's related, but video stopped working as well after migrating to KDE 4.3: Dragon Player just hangs when I try to open a video file ?
And yes, my user belongs to audio group, and video...

Sound Suddenly Stopped Working After PC Restart

The title says it all, my sound stopped working after I restarted my PC, I got these screenshots to try to help.
http://prntscr.com/4urkk9
http://prntscr.com/4urkoc
http://prntscr.com/4url97
My PC is a Compaq CQ58, and this same thing happened before over a year ago, I simply system restored it, but I don't want to have to do that again.

Hi
Go to device manager and uninstall the sound driver then restart the unit and check if sound is back.
Try to update the Sound and Bios from HP website.
Let us know how it goes!

Sound suddenly stop working.[SOLVED]

I just rebooted and then my sound doesn't work. I run alsaconf, edit the generated file. reboot and now it still (and the network!) doesn't work. I can't recall modifying anything prior to the sound crashing. I get this pop-up telling my my sound is already in use or bad configured. Can it be that I launch a program that use OSS without knowing it? How can I check that? Other suggestions?
/Richard
BTW I can still use the web but it doesn't launch automaticly anymore (ie have to run dhcpcd).

I get this feedback when running xine:

Hi! i need help... my hp pavilion dv3500 notebook pc sound suddenly stopped working...

i checked the driver and it said that its working properly... sound is also not on mute...

thanks and hope to hear from you guys soon...

HI Nishanth1994,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion 15-e017tx Notebook and getting errors on startup with wireless and sound. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to turn on the computer you start to press F11 repeatedly till the menu opens. You can do a system restore. This helps restore your computer back to when things were working correctly.
Here is your driver page if you need it.
Hope this is helpful.
Thanks.

Media sound suddenly stops working

I have had my Droid X for a little over a year now, and all of a sudden this week none of my media apps will play sound. I'm still getting ringtones and such, but when I go to use the MP3 player, Netflix or Youtube, no sound comes out. I have checked in my sound settings and everything is turned up all the way. I noticed this problem the other day and did a factory reset on my phone, and still no change. What can I do?

Hello to you Cthomas89!
I don't know what I would do without my media on my phone! I'm so sorry you're having issues with your Droid X.
I appreciate you taking the time to perform a Factory Data reset on your phone. I'm very surprised this didn't correct your issue.
Is this happening through a bluetooth, wired headset, or through speaker phone?
Thank you for your patience!
