Basics from the User Guide are restart, reset, restore from backup, restore as NEW. Unless you've tried ALL of these, you're not done troubleshooting.

Sound and videos not working

Hello,
I bought my HP laptop almost a year ago for my first year of university and recently the sound has been stopping and starting.
The sound sometimes works fine, but other times it works to begin with but then within the space of a few minutes it stops and won't work again until I shut my laptop off and turn it back on again.
When the sound won't work, neither will any youtube videos or iTunes songs, they stay on 00:00 and don't play at all.
I've tried all the help given on this link: http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&docname=c03257712#N432 but to no help. My computer is all updated, the speakers say they have no new updates, and all my anti virus software says my computer is protected and under no threat.
When doing all the stages on the link above, the Step 2 'change stystem sounds' part says that 'the device is being used by another application' when checking each individual speaker, even though I have nothing else running. So I am a little confused at what else could be running.
I have read a few of the help posts given for this type of problem and apparently deleting the audio speakers from device manager hasn't been very helpful for some people and I am wary of deleting things and making matters worse.
If someone could please get back to me to help I'd appreciate it. If not I'll have to go into PC World to get it fixed, as my laptop is still under warranty and should not be having problems after less than a year of use.
Thanks

Hi,
Try the following.
Open windows Control Panel, open Windows Update, select 'View update history' in the left hand pane and then select 'Installed updates' link in the following window.
Locate update KB2962407, right click it and select Uninstall. When done, restart the notebook, open windows Control Panel, open Windows Update and select 'Check for updates'. You'll see the update you just uninstalled being offered again - right click and select 'Hide Update'.
After this you may or may not need to delete and reload the Audio driver - if you do, the procedure for using recovery manager to reinstall Software and Drivers is detailed in the document on the link below.
Recovery Manager - Windows 8.

Sound and settings not working ("Task Host Window" when closing)

Okay I am not sure where to focus exactly and I am not good at articulating these problems because I don't know much about computers, so I will just try and make a simple list of problems that occured at the exact same time, and therefor must be related:
I had just installed an update which took quite a while.
Every time I close down my computer it says "Task Host Window" has to be shut down. It says underneath (translated from Danish): "Assignment host is stopping background tasks
Sound doesn't work. Not normally or with different speakers or anything like that. The sound icon shows a red circle with an X
Automatic start up programmes such as Dropbox and Sticky Notes don't start up unless I do no manually
Most parts of settings just show blank when I try to access them eg. control panel and parts of PC settings
Saving words documents (I suspect because OneDrive has to be accessed first) is really slow, but once they are saved ctrl+S works like a charm
I have tried:
I heard turning off onedrive would help, but when I go to PC setting -> OneDrive it doesn't respond
I tried a HotFix for Task Host Window but nothing happened
Trouble Shooting the sound by clicking the sound icon (which has a red circle with an X) tells me 'one or more sound services isn't running' and when I click 'see more ways' it goes to a blank site within control panel
I suspect there's some simple way to start the sound manually and it's simply being blocked, and honestly if I could just get it to start manually when I needed it, I could live with all these other problems. The sound is the most important!!
Thank you in advance
ps. I haven't been able to find my exact operating system and notebook information due to the problems with the settings, but I know it's an EVNY with a sound system by BEATS BY DRE and the operating system is windows 8

All sounds and vibre not working

Hi there
My iPhone 4S had stopped working sounds and vibratig at all (calling ,music,video,game ) sounds suddenly.
I can't hear sound who's calling me and he not hear my sound.

Have you tried a different pair of headphones? Does this happen with both the external speaker and headphones? Have you tried a hard reset of the iPod to see if that makes a difference? What about a restore?
Does this only happen with certain tracks?

Powerpoint 2011 mac - video and audio not working

Hello all,
I am using Powerpoint 14.2.5 on my mac running osx 10.8.2
When I try to add video (.MOV / WMV / MPEG-4 etc) or audio files (MP3, AIFF, WAV etc) they appear on the slide but the play controls will not work.
Also when I play my slideshow they do not function.
I can get a movie to play if I set it to play automatcally when that slide is reached but even then it only plays half of the video not the whole thing.
In any case I only want it to play when you click to the next event in the slide show.
Very frustrated.
QuickTime is installed ok.
All updates are installed for both osx and Powerpoint.
Any tips?

Animation and Audio not working

I'm having trouble making my Presenter presentations act like the original PPT. PowerPoint presentation has audio and animation that work fine in the slideshow mode. If I publish it in Presenter, no audio comes over automatically. I tried the Import from Presentation option which brought the audio in but when I publish, the animation that had been synched with the audio in PPT is gone. What am I doing wrong?

Sound for recording video and audio not working

I have tried everything to get the sound to work. I have reinstalled the audio driver. When I go to soundrecording.exe to see if I can record sound it gives me a message "An audio recording device cannot be found." Please help this is driving me crazy.

well, since people can hear you on a call, it's not a hardware problem with the microphone.
It appears to be something wrong with your recording apps -- the camera (in the case of video) and whatsapp.
First attempt would be to:
a) install another camera app with video capability and see if IT will record audio. and
b) uninstall and reinstall whatsapp to see if that fixes the problem.
If that doesn't work, to a backup, then try a hard reset and re-install the apps one by one, confirming that recording works after each install.

Mac Pro Locked Up and Now One Video Card and Audio Not Working

Last night, my Mac Pro totally locked up to the point I had to power it off to get it to do anything. When restarted, one of my video cards and my audio are no longer working. I have dual monitors so tried switching the connections to see if it was the monitor and that was not the problem.
I tried doing a formal shutdown after the restart and this also did not clear up my problem.
Everything was working fine prior to the lockup. Any suggestions would be much appreciated.

IChat video and audio not working (yep, me too). Help? Help!? etc. :)

I'm not here to start a rant about Apple or iChat AV. Before 10.4.4, my mate and I had some great chats on iChat AV. He had a cam attached to his Mac and I could see the video absolutely fine. We used to do audio chat, too. It worked fine.
Now we're both on 10.4.4 and I've got a built-in iSight on my new iMac. Obviously, I want to try out some 2-way video now. It won't work for me, though.
We can text chat, we can send files. We can't use audio chat anymore and neither can we use video. It's the old 'did not respond' problem.
Nothing has changed in my setup, connection-wise. I've got a healthy broadband connection which is connected to a BT Voyager 250 modem. Connected to this, via ethernet, is my Airport Express.
I've tried eliminating the Airport Express from the setup, but it makes no difference in this case.
I don't really know a lot about port forwarding and telnet sessions, so... be gentle. Hopefully someone here can help get it working.
Many thanks,
B

HI,
Depite some factual errors
(it's the camera's fault your relatives are on MSN and "everyone is due a rant on the money you have spent" - not to mention the camera is at fault for the shortcomings of the applications other than iChat), it is a very nice rant.

Microphone and Audio not working on Windows 7 (x64)

Hi.
I uninstalled Windows 8 two days ago, trying to put again, on my bootcamp partition, Windows 7. The first time I tried the GPU just wouldn't work, so I installed everything AGAIN to make it work fine. I downloaded those "iMac Late 2009 for Windows 7 Drivers" from apple.com and it was pretty successful: GPU was working again and so did my native resolution, 2560x1440 (I have a 27" Late 2009 iMac with i3). When I tried to talk to one of my friends on Skype I found out the (internal) microphone wasn't working, and so did the audio (also internal). So I installed EVERY drivers I could (realtek, cirrus, bootcamp 3.0, 3.1 and 3.2, I took some drivers from Driver Genius). I don't really know what I have to do!
Please help me, I'm in a tremendous situation.
( sorry for the bad english, I'm italian.)

Che dice Windows nella finestra dei dispositivi audio? Per me l'errore (su Windows 8) era che diceva "no audio devices are installed". In quel caso bisogna fare right-click nello spazio di quella finestra e selezionare "show disabled devices" e "show disconnected devices". Quando ho fatto quello sono riapparsi sia il microfono sia i parlanti. Spero che ti abbia aiutato in qualche modo.

Ichat video and audio not working

They used to work just fine. Have no idea what is going on. I get the error 8 that every one around here is talking about. I've tried the suggestions of bandwidth, firewall etc. Don't know what else to do.

Hi,
Error 8 is about either Ports or the Way the LAN is set up.
SO has anything changed in the way you have set up your LAN ?
Also are you using a Routing device that gives the computer it's IP (DHCP) ?
If so do you also use Port Forwarding to open the ports for iChat ?
If this is the case is the computer at the IP that the Port Forwarding points to ?
