Windows 7 + Realtek HD Audio = A whole lot of frustration

System Specs:
Workstation Model: Media Center PC m7790y
Processor: Intel Core 2 CPU; 6400 @ 2.14 GHz
Operating System: Windows 7 Professional (32 bit)
Using onboard sound
Realtek High Definition Audio; driver version 6.0.1.5910
Speakers: HP vs 19e
So, last week, I upgraded from Windows Vista Home Premium (32 bit) to Windows 7. I get no sound from my speakers.
I downloaded HP's Spring 2007 Original Realtek High Definition Audio Driver, but that, of course, is for Vista and will not run on my system (I get an error message with the following number: 9998).
I also downloaded Realtek's "solution" to this problem (I tried both the Windows 7 and XP versions), but that didn't work either. I have tried running all of these drivers in compatibility mode for Vista (Standard and Service Packs 1 &2) and XP (Service Packs 2 & 3), but to no avail.
I contacted Microsoft about this and they told me to do exactly the same things I just described doing.
Before anyone asks, yes, I have tried a pair of headphones, I have tried using different speakers, I have checked to make sure everything is plugged in properly. And my PC is out of warranty, so HP won't help me unless I pay them.
Can anyone help?

Steve, did you check in the Control Panel to assure that the sound device is the default? Also, that all of the boxes are checked that should be and those that are not supposed to be, aren't? Check one at a time, so you will know if it is working or not. I have had this happen to me over the years and have fought it until I was ready to throw the computer out of the window. Does that describe how you are feeling?
Also, did you run Windows Update to see what happens? Some have done this and actually got the driver that they required.
Let us know what happens.

No sound from laptop speakers after Windows update installed Realtek HD Audio

Laptop is HP6626US with Windows Vista 32 bit SP2.
I had an error with Windows Update which was recently fixed. When I ran the update Realtek HD Audio was installed, among many other items. I now have the red circle white X by my speaker icon and do not get any sound out of internal speakers.
The Driver version is 6.0.1.6662
Direct X version 11.0
Audio Codec ALC 268
In Device Manager Under Sound, video and game controllers Realtek HD Audio is listed with Unimodem Half Duplex Audio Device if that is helpful.
Help Appreciated.

Hello,PaulM25.
I see that you're having an issue with the sound on your notebook. Typically this means the Drivers don't exist and can also be considered as a hardware issue.
I have a couple of questions for you before we get going.
This is your notebook (HP Pavilion dv6626us Entertainment) correct?
Did this issue occur after you updated the audio drivers?
Now, you can go ahead and try these steps to resolve the issue.
Please completely remove the drivers for the Audio Device in Device Manager and “Control Panel – Programs and Features”.
Reboot the computer.
Please check if the device will be installed automatically after the computer starts. If not, please go to Device Manager and then navigate to the Audio Device, right click on it and choose “Update Driver software”
If the issue persists, please try to manually install the device driver which comes with the computer to see if it works. (You can also go to HP website to install the drivers. If you cannot find it, please give me the detail information of the device or the computer, such as brand, model, etc., I will help you search for the proper driver.)

Realtek AC97 Audio CutOff (ALC655)!

Hi,
After a month from replacing my mainboard (old board was fried during system shutdown along with PSU), I am starting to experience these weird problems...
I use the onboard AC97 codec on my MSI 865PE Neo2 mainboard which is manufactured by Realtek and reported by the driver as an ALC655 codec...
It all started a week ago when I was playing Far Cry when the all sounds suddenly went dead , I simply exited Far Cry and re-opened it and it was fixed for a while when it went dead once more, so I exited and tried to run WinAmp and listen to my MP3s and again problem was fixed...
But I can't remember exactly when, maybe 2-3 days ago when the sounds starting going dead after a few seconds or a few minutes in ALL DirectX games (RedAlert 2, Toy Story 2 , Generals, Far Cry...everything!), even when running WinAmp, it would suddenly stop playing, and clicking on Play again did absolutely nothing! (does the same with WMP), even MS-DOS based games (ex: RedAlert 1) lose sound, Yet when I logoff Windows XP and logon again, it works once more but cuts off again after a few seconds.) !!
Here's what I've tried:
1. Re-install DirectX 9.0c
2. Re-install Realtek AC97 Audio drivers (original one on mainboard CD)
3. Decreased Sound Acceleration to in DXDIAG
4. Did a fresh install of XP on another partition with just system drivers...
--> And still the same problem !
Note:
1. Even when the sound is dead, when I logoff, Windows XP is magically able to play the logging off sound ! But when I re-logon and start (eg: Far Cry), the sound is immediately cut off after a few seconds !
2. If I continue to play even after the sound is dead, I can occasionally hear the sound suddenly popping back on for just a fraction of a second playing sounds that were supposed to be played when it cut off..., but it doesn't keep that way and pops dead again..
Any suggestions ?? Any help will be really appreciated...

Hey guys !!
--> I just finished downloading this file from MSI LiveMonitor !
>>>> Here's what I've done just now:
--> I removed Realtek AC97 Audio from Windows Device Manager...
--> Downloaded Realtek 5.10.0.5750 driver from MSI LiveUpdate....
--> Installed Driver...
--> It asked for a reboot but I refused...
--> Running my whole MP3 collection in WinAmp!.. Seems that the problem's fixed !!
-> No sound cutting whatsoever till now !! Been playing for 20 min. non-stop...
Here's info ripped from driver pack's README.TXT file:

Realtek HD Audio Issue

Hello fellows,
Unfortunately I've been having problems with my Realtek HD Audio (includes THX TruStudio Pro and Dynaudio Premium Sound Technology) with my Windows 8 x64 MSI GT70 whenever I open up a game file and start playing for 1-2 minutes (WoW, Diablo III, SCII). I've tried all the different settings in the Audio Manager but it didn't help.
For WoW, I seem to have resolved most of the problem (an issue with the sound where makes clicking and buzzing noises) when I opened up the loading screen and chose to open it in 32-bit instead. Unfortunately, SCII or Diablo III don't have that option in the loading screen. For WoW, the problem is mostly gone but an occasional click here or there comes, a lot softer than before. Before, it was unbearable so I had to turn the sound off completely.
Anyone have suggestions to stop it for good? I'd appreciate the help. I've already reinstalled everything concerning the audio system, it says it is working properly, and I have the latest driver (also tried disabling THX) and the problem still arose after that. I've also tried to run the programs in compatability mode but that didn't work either. Everything else aside from games sound just fine. In any case, changing to the 32-bit helped with WoW. How can I do that for the others?
Cheers,
A

Thanks for the suggestions. Even with the default sound driver, I still experience the problem. I contacted MSI and they think it may be a hardware issue. That was the only thing they said. I have my doubts, however. If it was a hardware problem then why don't I have any audio problems when playing music or watching videos?
Anyone have any other ideas? I really don't want to send the computer away, going through that effort and then to find out that it wasn't a hardware problem after all

Realtek HD Audio: Output:OK, Input (Mic): NOT WORKING??!?!?!?!?!?!?

Hi guys,
I am going to tell you and ask for your advice the wierdest thing happens to my 14-month old Pavilion 6300 series:
- The PC has Realtek HD Audio built-in (on-board) and having the latest driver (I downloaded off from realtek.tw, latest is 5.10.0.5874)
- Before I installed that Realtek driver, I had installed Microsoft UAA Bus driver for HD Audio (version 5.10.0.5010)
- I am running Windows XP Professional SP3
When I plug in a headset (with mic of course, for skype), strange things start like this:
1. I can hear the output sound, the jack can detect which plug I plug in
2. But the INPUT (back or front) which is in my case, the MIC, DOES NOT WORK AT ALL.... Jeeze, it drives me NUT!!!
3. I have turned on ALL the volume related to "MIC" but to no avail. Even the Recording mic volume is grey-out... really no-hope?
4. I did the Hardware test, it could not detect the mic (no movement from the sound bar)
5. The headset works well on other machine!!!!
Can somebody tell me that the onboard card got a problem and I have to buy another card???
Thanks a lot in advance guys, really
James
Message Edited by Jamesnb on 06-26-2009 12:19 PM

now what you can try is can try to test the MotherBoard once and if there is any issue with the onboard card then you have to replace the card.
if there is no issues with the MotherBoard then try entering device manager in safemode and uninstall the drivers once and check if its working.

HP update of Realtek HD audio SP64224 version. 6.0.1.7071 fails -5009 : 0x8002802b

Hi,
Just got ouf of the box HP Pavilion 15-n056so.
EDIT: product number F4C38EA#UUW
All windows 8.0 updates available was installed, then 8.1 windows update was installed.
Origin and battlefield4 was installed.
I used HP Support Assistance to install those drivers and programs it suggested but ran into problems with Realtek update SP64224. This fails. I tried to find more details but none in event viewer.
Did some searching and found from HP sites the same driver package separately downloadable.
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=fi&lc=en&dlc=fi&softwareitem=ob-125625-1
When I tried to install this manually (not using HP Support Assistant), I got error:

Did some searching again and found some discussions where realtek hd audio should be uninstalled from the Programs and Features. Did that , rebooted, tried again installing through HP Support Assistance + manually and faced same problem again.
I tried renaming folders:
C:\Program Files\Realtek -> C:\Program Files\Realtek_old
C:\Program Files (x86)\Realtek\Audio -> C:\Program Files (x86)\Realtek\Audio_old
änd then running installation manually again. Same problem.
I know what error code means, but why it appears is mystery as well as how it could be installed successfully.
I am also little worried, that when and if the update is done I might face other issues like:
http://h30434.www3.hp.com/t5/Notebook-Display-and-Video/video-driver-stopped-responding/td-p/3270697...
I do not know completely what benefit it brings to update the driver to the one suggested by HP support Assistance. It is purely annoying that I can't get the update done as there should not be anything disturbing the installation + the exclamaison mark is extremely annoying as well.
has anyone else had this kind of problem?
Any ideas how to resolve the problem?
Thank you for assistance.

After I updated my audio driver (realtek hd audio) the MaxxAudio tab in the realtek window was lost...
To fix it, I have tried to "downdate" my driver, but I always can't see MaxxAudio.

As I had upgraded my computer to windows 7, I have tried to install an old version of this driver which was in the Toshiba Upgrade DVD, but no MaxxAudio tab in the realtek window...

Can't find MaxxAudio tab in Realtek HD audio manager after update

First, sorry for my bad english, but I need your help =)
After I updated my audio driver (realtek hd audio) the MaxxAudio tab in the realtek window was lost...
To fix it, I have tried to "downdate" my driver, but I always can't see MaxxAudio.
I have also search solutions in Internet (Toshiba drivers page, forums, realtek.com...) I have found nothing.

And now, I have no Idea anymore, that's why I ask you.

It's a Qosmio X300-16M (windows 7 64bit)
I downloaded the last toshiba's sound driver (for win 7 64bit), but it's as if it doesn't contain MaxxAudio anymore... (but the file maxxaudio.dll is still in realtek directory)
It worked correctly after Windows 7 update, (that's why I tried to reinstall the audio drivers which were in the DVD... but it does not have resolved the problem.)
And all my system restore's points have been lost after a wrong bios update or something else (but this isn't a problem anymore)
Now, my computer works correctly, my only problem is that the MaxxAudio tab (from Waves Audio) in the realtek audio manager disappeared... (It just makes a better sound...)
And I just want to know if it's a curent problem or not... and if someone can fix it

Realtek HD audio driver updated

For my HP Media Center m7060n with Windows XP the HP site indicates the most updated driver is as of Sept 2005. I am having problems with Power Director 9 which I bought a couple of weeks ago and their tech support believes one of the reasons is an out of date driver. I am reluctant to use someone other than HP for the driver primarily due to it being from unknown sources and thus a risk, or at least a perceived risk.
Any ideas on whether or not the 2005 version is the best for my situation and if not how to update it?
Thanks. This is my first time to try this forum.

I retried the effort and was successful at downloading and installing the new driver. HOWEVER, now I have no sound. Under control panel, sound and audio devices, in the audio tab, it now shows "no playback devices". Here is what dxdiag showed before and after:

Realtek HD Audio driver disappears after installing an ATI Radeon graphics card

My Realtek HD Audio driver disappears (from both the Vista "Sound Manager" and the "Device Manager") and is replaced by an ATI HD Audio driver after installing an ATI Radeon 5450 graphics card. I've tried un-installing the ATI Audio driver and re-installing the Realtek Audio driver. But, upon rebooting, Vista automatically re-installs the ATI Audio driver (and the Realtek Audio driver, which I just re-installed, is no where to be found after rebooting). I'm using an HP a6110n desktop running Windows Vista.
This question was solved.

Hi:
I bet you were unpleasantly surprised by that!
The fix is simple:
Go into your system setup (BIOS) using the F10 key.
Find your device configuration menu. In that menu there should be a setting for your onboard audio. It is probably set to Auto.
Change the setting to Enabled. Hit the F10, key there and again when you save your settings and exit.
Now your onboard audio will be back and your HDMI out audio on your graphics card should work too when you need it.
What happened was when you installed the Video card with HDMI out, there is an audio chip on the video card for HDMI. The PC sensing a new sound card, just disabled the onboard sound card because it thought you didn't want to use the onboard card anymore.
Changing the BIOS setting to enabled tells the PC to use the onboard audio card as well as any others you may have installed.
