View Solution.

Hi:
You go into the BIOS, select the Advanced Options menu.
Go to the device configuration menu and there will be an onboard audio setting.
It will be set to Disabled. Change the setting to Enabled. Save the setting there by hitting the F10 key, and again when you exit the BIOS.
After you reboot, you will have the onboard audio back.

Sound Problem After Installing iOS 8.1

Hello, after updating my iPad to iOS8.1 it started making weird noises, kind of the same ones you get while blocking it or getting a notification but with a little of a "robotic" twist. Restoring it seemed to had fix it until I tried to get the 8.1 again. I was just wondering if someone its having the same issue, and if so, whats the solution. Do you think that i'll be treated on the 8.2 version? I had the same problem with my iphone 4 once and couldnt get it sorted out.

I successfully got my iPhone 6 messages sound by following Timothy Holt directions.
Thanks Tim.

What you have to do, and this appears to be essential after you update the OS, is to reboot your phone.
1. Hold down the sleep/wake button and home button simultaneously.
2. Let go when the Apple logo appears and the iPhone is booting up.

Have you tried copying it to your computer's iTunes via File > Transfer Purchases and seeing if it plays ok on your computer ? If it does then try deleting it from your iPad and then sync it back and see if it then plays. If not then you could use the 'report a problem' link from your purchase history : http://support.apple.com/kb/HT1933

Sound Problems After Installing Lion

I see many are having issues with sound after installing Lion. I have sound and then will lose sound after closing and reopening. I have to restart to restore sound. This is getting old quick. Does anyone know a fix or if one is coming? Thanks!

Not sure how much it helps, but here is my experience:
I have found that after a while, midi-style sounds stop playing. Most obvious to me is the crinkle tune when throwing away trash, or the click when placing something into the trash. When these sounds stop playing, I can still set the volume (and the up/down volume sounds will play) but the midi tracks don't start playing.
A while back I was hunting for a solution to this problem and rebooted and messed around, etc, etc. One person suggested changing the midi format since they knew there was a bug in the midi playback in Lion (a beta comment I think). So I used the Audio MIDI Setup application to change the Built-In Output format to 2ch-32bit float. For a while the sounds were back.
Just now, I noticed that they had disappeared again, so I went back to Audio MIDI Setup and changed it back to 2ch-24bit Integer. All of a sudden, a stream of old sounds started playing - presumably everything that had not been correctly played for a while.
Not sure if it will work again, but next time the sound vanishes, I will try to change the format again and report back what happens. My guess is that just changing the format will cause the queue to reset and play any old sounds. Then the sounds will work for a while until the bug is triggered again. Perhaps the workaround for now is to just keep flipping the Ouput MIDI format?

VssNullProver stopped after installing Update Rollup 3 for System Center Data Protection Manager 2012 R2

I recently installed Update Rollup 3 for System Center Data Protection Manager 2012 R2.
As part of the update I updated all DPM Agents, including the ones on our Hyper-V Servers (which are part of a cluster). I also rebooted every DPM Protected Servers. After reboot all Hyper-V Servers raise a warning that the VssNullProvider service has stopped.
Backup seems to work properly. I can start the VssNullProvider service manually. But after the next backup the service it is stopped again. Exactly the same issue occurs on our test Hyper-V Cluster. All our Hyper-V Servers run Windows Server 2012 R2 and
we use System Center Virtual Machine Manager 2012 R2.
Something is not ok with Update Rollup 3. Any suggestions?

BT Sport HD: sound stops after a minute or so

Hi
Firstly I was impressed with the launch show last night - well done BT!
I have a YouView box and Infinity BB. I tried to watch BT Sport 1 on HD (channel 510), but after a minute the sound stopped. I could change channels and then come back to 510 and the sound would be there, but again would stop after a minute or so. This happened on all the Sport HD channels.
Note that the SD Sport channels (507 - 509) were absolutely fine.
I tried re-booting the box, but it didn't solve the issue.
Has anyone else had this problem?
Thanks
Simon

This is a me too message. I suspect it is a Dolby digital problem. The picture has been rock solid so far. I'm using Youview.
I have a followup and a workaround to this problem
I contacted BT and they are convinced that the problem is due to the powerline adaptor, which was supplied by BT along with the Youview box. They tell me that their technical help files state there is not enough bandwith available. They are going to send me, free of charge, a 10 metre ethernet cable for a direct connection to the router. I was very sceptical when I was told this over the phone and my subsequent action below confirms my scepticism.
After the call, I tried the following setting change on the Youview box. I went to settings>tv signal & quality>HDMI Audio format and changed this from surround to stereo. This effectively turns off the dolby digital output. The problem disappears! Of course, this turns off dolby output for all HD channels on the box which is not desirable.
This makes me convinced it is a dolby audio problem but getting BT to recognise this might be more difficult. I hope they can fix the problem soon.

No sound anymore after installing XP Home on Satellite Pro 4600

Hi gents,
I don't have any sound more after I have installed winxp home on my Pro 4600. I used the problem solve wizard but without any improvements. I have also installed the latest sound driver and bios.
Looking forward to some replies, .............Harry

He Eldorado,
You teached me a wise lesson "first look to the obvious things". And yes it was the volume controller at the side (did not know there was one). But anyway problem is solved
Thanks...........Harry

Video player in iPod 60Gig. Sound stops after a while playing large clips

I have been converting DVDs and large video clips into iPod MPEG 4 format for the iPod with the Xilisoft DVD to iPod Converter 4. This softwrae works just great and the files plays well on my PC with Quick Time player as well as others. When loaded to the iPod they all start OK but the sound disapears after a while. If I fast-forward or backward then it works for a while again.
I do not see this behaviour with short clips (3-5 minutes)
As far as I can see this is related to the MPEG4 player in the iPod. Anyone have a similar problem or some resolution to it.

Nope,
But I just discovered that that it is actually not only the sound that stops working but rather the whole video that has a "hick-up" and then when it continues the sound is gone. If I fastforward/rewind then it seem like the player rocovers and play the stream correctly again.
What are the Mp4 clip prefs you have used when converting?
I am planning to try some other settings when converting to see if that makes any difference but I doubt it will help. I think we will have to wait for a "better" i.e. working Video Player for the iPod ...

Audio sounds horrible after installing iTunes vers 10.5. How do I restore the audio quality?

Windows Xp bad sound quality after installing itunes 10.5

After installing itunes 10.5 to be able to get the ios5 update my itunes plays every file with really bad, distorted quality. I try other players even Quicktime works fine. What could be happening?

Try to download, and install the latest Realtek HD Audio driver.
Here is the download link:
http://www.realtek.com.tw/downloads/
Select the second options (High Definition Audio Codecs (Software))
And when you install this, i think everything will be good.

Sound stops after a few seconds

I have a HP G61, Product Code VY441EA#ABU. OS is Windows 7 Home Premium 64-bit. Audio stops after a few seconds. This happens on TV i-players, BBC News website clips, football streaming sites, even the HP Support site's tutorials. I have done a System Restore to a point when I know this was not a problem. I have downloaded the audio driver for my laptop from the HP site. I have tried the MS audio troubleshoot fix, which found no problems. I would sure be grateful for any other ideas to try!

Hello GrahamBIOM,
I understand while viewing a video or listening to some different content, you lose audio, is that correct? I will do all I can to assist you with this issue.
Does the issue occur when you have headphones inserted? If you are not sure, if you have a set of headphones available could you test that please?
Please respond back at your earliest convenience with results.
Thanks

Kernel panic after installing a USB 3.0 PCIe card

Hello everybody,
I have a recent issue with my Mac Pro (early 2008). I just bought a USB 3.0 PCIe card from eBay for my Mac Pro and as the seller mentioned there are drivers for Mountain Lion. After installing the cards drivers that the seller sent me and plugged the PCIe card, whenever I connect a USB 3.0 device (I have only one) the Mac Pro is forced to reboot. If I leave the drive connected after the reboot I get a kernel panic message during the "Grey Apple Boot Screen" and the computer continues to reboot again and again. I have no issues with USB 2.0 devices at the same card. The kernel I get is the following. Does anyone have any idea? it seems like the kext installed with the card {net.osx86.kexts.VLIUSBXHCI(1.2.4)} causes the problem but the seller told me he has sold a lot of them, and i 'm the first with such a problem.
Thank you in advance.

That card appears to be a Via Labs VL800 and Via has no Mac drivers, so gosh only knows where that kext came from. I'd highly recommend you remove it and consider getting a card from Sonnet where you can get proper Mac support:

To me it's not worth saving a few bucks from some generic card/driver pair to risk problems and perhaps even malware.

Low Profile Graphic Card

Anyone has any recommedation of any low profile GPU that can run with a 280W PSU and is better than Geforce 9300GE? Thanks

Low profile as in small-sized cart? The ATI Radeon X1600 is probably the smallest card that has dual-link DVI that will drive the 30" display.

Aperture install with low spec video card?

Is there a way to avoid the installer routine (when installing Aperture) that identifies your graphics card? Apterture has identified that my Geforce 5600 card (in my 2005 G5iMac IBM chip 1.8Ghtz) is not able to cope with running Aperture, and quits the install process.
Having heard stories of people running Aperture on Powerbooks, I'm sure I could cope Apterure running slower (or whatever!) without a new graphics card!
Any suggestions please? Many thanks
iMac G5 Mac OS X (10.4.7)

Before going on a long trip, I tried to install it on my 1.42 mini - found a hack that allowed it to be installed, but ... then the program wouldn't run - saying that the hardware was insufficient. Having used it for a couple weeks on this MacBookPro I was "forced" to buy to run it while on vacation - it seems that some parts of Aperture run much faster on the laptop over my G5 2GHz dualcore (corrections and cropping, etc.), and other parts are slower (to a snails pace) - like creating thumbnails - next to worthless. When I get home, I might seriously consider getting a better graphics card in the tower - as cropping is a drag with the standard card I have in it.
