IDT High Definition CODEC has stopped working

I own a Pavillion dv6 Entertainment PC with 64 bit Windows 7 Pro as its OS. Until yesterday, the CODEC provided great sound. Then it began expeiencing probles, and today quit working entirely.
I consulted Windows Event Viewer and found that, on multiple occasions beginning mid day yesterday, it began recording events with an Error message ID of 1005. Looking further, each one recorded that Windows could not open the same file: C:\Windows\System32\AudioEng.dll. and that Windows had stopped the service Windows Audio Graph Isolation as a result.
Windows Message Center recorded that it had tried and failed on 6 occasions to open this file. Following its suggested dolution, I ran CHKDSC with both options enabled. Upon completion, its report showed 0 Bad Files processed and - bytes in bad sectors. Yet the problems persist.
Is this a problem with a corrupted driver? If so, how do I find a driver newer than version 6.10.6276.0, released in 2010?

Hi,
Please try a newer one:

No audio (IDT High Definition CODEC) after switching to windows 10

I upgraded to Windows 10, and sound was fine for a couple of days. Noticed it was off today when I was trying to figure out why iTunes wasn't playing songs (whole other issue). I've searched and spent hours trying everything I could find. Headphones work fine when plugged into the front. -Right clicked speaker, went to playback devices, tested.-Checked for driver updates, said there are none, check again, says it can't finish updates. Finally get them done, doesn't fix it. Try uninstalling devices, uninstalling drivers, both at the same time and seperately.-Use hp support assistant, and try everything that it suggests. No change.-System restore, no change.-Checked to make sure the master volume was up-Disabled, then enabled devices Any help would be amazing! Thank you in advance!

Windows 10 IDT High Definition Audio Codec doesn't work properly on Hp Envy 20d001-la after update

I'm using a Windows 10 just updated pc, Hp Envy 20 d001la, and I'm having problems with my speakers, they work with IDT High Definition Audio Codec driver. It has beatsAudio available, but the bass don't sound the right way, I can barely hear it. It has a low quality sound... the worst quality. This problem isn't new for me, when upgraded to Windows 8.1, also the problem apeared, when the driver released with a new version, specificly for Windows 8.1, but how did I solve it? I only installed the Original Audio Controller found on Hp Support & drivers page (It was designed for work on Windows 8 64 bits). So, I know Windows 10 is newer than ever, and sure of some bugs or little corrections after updating. But when I try to install the Windows 8 Original controller to get the extreme sound quality again, it can't be installed. The problem says: "Operating system doesn't has the requirements" The new drivers have low sound quality (driver Windows 8.1 & Windows 10 versions) If I could install the Windows 8 version driver, I'm sure the sound quality returns. Thanks in advance.

Hi! Thanks a lot, I've tried the solution you've given me, (extracted the setup file with winrar on a folder and search for the driver as you said) but an error message shows: "There are not compatible drivers on the selected folder, try with one for Windows x64" It happens with both drivers I have, W8 & W8.1 versions. And also I have other problem, I didn't connect the headphones when trying solving the problem, and when I connected them, a surprise: The speakers didn't shutdown, they continue playing sounds and the headphones and speakers were playing sound at the same time. I've checked for the internal connector and The connector is clean. Then I tried to install W8.0 IDT setup manually clicking on the files extracted, the process finished succesfully, and system restarted, the sound quality came again, but still when I connect the headphones, the speakers don't shutdown and sometimes music stops. The problem is with all versions of driver I tried, the W10 got by Windows update, the found on Device Manager, the W8 , W8.1installed manually, But not worked.I hope in a future upade the problem could be solved, because I listen to music always only on headphones to avoid disturb others. Thanks, I'm trying a new method if is kanown for you. Thanks a lot.

Hey,
Try installing this driver: IDT High-Definition (HD) Audio Driver
If that fails, try using the HP Recovery Manager to roll back to the factory installed driver.
Test after both. Let me know if either option worked.

Keep having to disable and re-enable my IDT High Definition Audio CODEC, what's wrong?

Hi!
I have a Pavillion Touchsmart Sleekbook 14" with Windows 8 that I bought new about 7 months ago. I have not yet updated to Windows 8.1.
Recently I have noticed that my audio will suddenly stop working. This typically happens when my computer has been sleeping and I start it up again. The audio does not come out through the internal speakers or headphones when I plug them in. I have not tried external speakers but I imagine the result would be the same.
If I go into my Device Manager and disable and re-enable the IDT High Definition Audio CODEC the sound returns. All sound devices I have listed are related to this IDT High Definition Audio. I have tried updating the drivers, however it informs me the most updated drivers are already installed.
I am not entirely sure what is causing this problem, but I do recall installing a Windows or HP update awhile back regarding IDT High Definition Audio. I believe it was an optional update.
EDIT: After doing some further research it looks like it is related to that Windows update and the compatibility of their IDT audio drivers with Windows 8 or 8.1 does not seem very good. If all else fails I will try uninstalling the IDT CODEC all together and use the default HP audio.
Has anyone found a solution that works for them regarding this issue?

IDT High Definition Audio CODEC v. 6.10.6395.0 Upon installation I have very low audio output

IDT High Definition Audio CODEC v. 6.10.6395.0. 5/21/ 2012
Upon installation I have very low audio output! Screen Shot Screen Shot 2
I have tried:
un-installing and reinstalling the drivers.
Installed the original drivers via HP's website sp53222 for my particular model. HP Pavilion HPE h8-1070t
Any suggestions? would be greatly appreciated. It would appear IDT who I also emailed and they never responded is responsible for a codec pack that is not fully functional with this motherboard.
was wir lieben meistens nicht kriegen

Did you access the Catalyst Control Center in programs and look at the latest updates for your graphics card and make sure you didn't download the audio drivers they self install and are checked automatically each time you attempt an update for the card.
Did you right click on the speaker in the system tray and go into recodring devices make sure everything is setup propper there sometimes they too can change.
I'm familiar with cakewalk but never used it on Win7 its been many years since I played around with that. If you are using the onboard audio card and it has worked before and not now if I were in your situtation I would attempt to reisntall the dirvers via device manager they do sometimes become corrupt especially if you picked up any malware that was removed by your antivirus software due to the drivers and malware both reside inwindows\system32.
After the reisntall of the drivers if the issue is not resolved I would upgrade the audio card with a PCIe x1 component such as:
Creative Labs SB1040 PCI Express Sound Blaster X-Fi Xtreme Audio Sound Card
http://www.amazon.com/Creative-Labs-SB1040-Express-Blaster/dp/B000W7PNZI/ref=sr_1_1?ie=UTF8&qid=1357...
After I paid for a real soundcard with Recording: 24-bit/96kHz and Sound Output Mode - 7.1 and bypassed my onboard audiocard I never had any issues again. My onbaord worked too in the begining for certain things than stopped mysteryously and the reinstallation became ineffective after a while so I decided the money for the tower was invested mainly in the CPU i7 the RAM and HDD.
*** Note if you did install the audio drivers for the graphics card you will have to change the onboard audio in the BIOS from automattic to enabled. Otherwise you will have no sound at all. So never take the audio drivers for the graphics card unless you need them for DVR recording or something. The PCIe audio cards are never effected by this however only the onboard audio. Another reason onboard is a cheap way to go and HP bundles it as cheap as it can my friend.
Good Luck again!

L channel sound comes through both L and R speakers after installing IDT High Definition Audio Codec

I noticed a sound problem on my laptop. The R channel works as expected but the L channel is split between the L and R speakers. After checking several different possibilities I narrowed the problem down to the IDT High Definition Audio Codec that I downloaded from the HP driver support page for my notebook model and operating system.
I uninstalled the IDT High Definition Audio Codec and restarted. This forced Windows to resort to using its generic "HD Audio Device" default. When I did this the sound was equally split between the L and R speakers as I would expect - L channel 100% though L speaker, R channel 100% though R speaker. I then re-downloaded the IDT High Definition Audio Codec from HP (sp59654.exe), re-installed it, and restarted. Immediately the sound problem was back - while the R channel comes 100% though the R speaker, the L channel is split between L and R speakers.
Please note this has nothing to do with adjusting speaker "balance". Both L and R channel volumes were set to 100% while investigating this problem. It's definitely some sort of incompatibilty between the IDT High Definition Audio Codec and Windows 8 64-bit or the sound hardware in the HP Envy DV6.
Here are my details:
IDT High Definition Audio Codec
Publisher: IDT
Date: 8/19/2012
Version: 6.10.6425.0
Notebook
HP Envy DV6-7200
Windows 8 64-bit

Here is what I would recommend you trying. Go to device manager and uninstall the audio driver. Once it is uninstalled, go to the device manager toolbar and select "Scan for hardware changes". After it completes, reboot the computer. Once the computer is rebooted, test the audio and let me know if that helped.

HP Probook 4530s IDT High Definition Audio Codec Speakers

As the title states:
HP Probook 4530s
Windows 7 OS
IDT High Definition Audio Codec
The laptop quit playing through it's speakers, but will play through the headphone jacks when plugged in. Tolerated it for about 8 months now. Recently, while playing with it I noticed that if the System is set to headphones and you double click on the slider it begins to play through the laptop speakers for approximately 1 second. You have to keep double clicking to maintain sound through the speakers.
Now, when I go to Speakers/HP Properties it shows that the sound is to the bottom 3.5mm jack & front 3.5mm jack. This laptop has NO bottom 3.5mm jack on it, only the front 3.5mm jack.
I have tried uninstalling and reinstalling, looked for new drivers and thought about installing an old driver but not sure how far back to go. Any suggestions would be a great help here. If you need more info please let me know what you need and where to find it and I'll provide it. Now that I know the speakers actually do work, I'd love to be able to use them again.

Now to help out with troubleshooting this here is a pic and what I think is going on:
Notice that the jacks are allegedly on the bottom and front for the speakers, only issue is there is no jack on the bottom and the front jack is for the headphones. the 10-18-2012 update that HP is tossing around ignores the fact that there is no bottom jack for the HP 4530s, g7, pavilion and dv7. I've had all of these over the years. It seems someone wrote a driver that is one size fits all and totally missed that these speakers are located someplace else.
So the question is, how do we reassign the location so it puts sound to the speakers?

CP4 / Windows 7 / IDT High Definition Audio CODEC / No worky

Hi,
I just got a new laptop with Windows 7 which has a IDT High Definition Audio CODEC sound card.
I got Captivate 4 installed and seemly working great... UNTIL I go to record the voice over. It doesn't recognize my microphone. It's not that the sound quality is bad - it just doesn't record at all. No green or red appear when calibrating input.
I checked and set volume in the sound control panel and it works there.
I tried to record with Soundbooth and had the same problem. Doesn't recognize it. Tired all available drop downs, line in, microphone etc.
I'm not sure what to do next.
Anyone run into this before or have any ideas about how to solve this?
Many thanks,
Aimee

FYI - for others who may experience this problem with Win7
This problem was resolved by a combination of steps.
1) updating the driver on the sound card to a Win7 compatible
2) replacing the .dll file in the captivate installation folder (see http://blogs.adobe.com/captivate/2009/03/audio_play_back_and_usb_mic_is.html)
I thought the updated .dll file by now would be a part of the CP4 patch but it isn't - so if you experience this problem you need both apply the patch and replace the .dll file.
Thanks,
Aimee
