Sound Playback Issue with IDT High Definition Audio Codec HP Pavilion dv6 Notebook PC

Since i bought this laptop, every time i use skype or the Windows Sound Recorder, i hear static that drastically increases in volume. Uninstalling the IDT High Definition Audio Codec prompts my computer to automatically install the driver again, this usually fixes the problem, but after restarting my laptop, the problem returns.
Does anyone know a permanent fix to this issue?

System loses the IDT High Definition Audio CODEC Driver ver 6.10.6491.0 after some time

IDT High Definition Audio CODEC 6.10.6491.0 installed in our HP Envy Notebook - C8U19AV with Windows Pro 8.1 64 bit OS, the system will lose the driver. When I go into device manager it appears that the codecs are there but the driver for the audio just gets lost. We have to repeatedly uninstall all the audio components and then reinstall again. This has been the situation for some time. I cannot say for sure but I have reinstalled the driver twice now for my wife and she has done it a few times. We commonly use the laptop connected to an HP2710m display monitor with an HDMI cable. From time to time we plug in Bose headphones as well. The diver revision 6.10.6491.0 was again installed today after fully uninstalling the prior driver. The common signature is the sound does not work at some point and when I go in and check on the audio codec it will report no driver loaded. Any attempt to run the sp63407 install package without ripping out everything will result in the driver install failing as some of the prior files will has security that prevents the over write of the old files with the new ones.
I can seen no obvious reason for this laptop to repeatedly lose the driver. Once the reinstall is done the sound works again but it is a real bother to have to repeatedly reinstall the audio driver.

Hey purplefacemcgee,
With your issue being for Windows 7, and not for Windows 8.1, the troubleshooting steps will be a little bit different. I would first suggest reinstalling your original sound drivers. I have included the document 'Using Recovery Manager to Restore Software and Drivers (Windows 7)', please click on the option for Hardware Driver Reinstallation, and follow through the steps for reinstalling your original sound driver only.
Now once you have installed the original driver, you will need update your sound drivers. You can do both the Windows, and HP updates that are recommended for your notebook from the HP Support Assistant. I have included the document 'Using HP Support Assistant (Windows 7, Windows Vista)', Please click on the option for Maintaining your computer and installing the latest software updates. Pretty much once you do have the HP Support Assistant open click on Maintain, and then Software Updates. Please install all updates that are listed. After the updates have been installed, please restart your notebook, and test the sound.
If by chance you are still experiencing the same issue, I would suggest running the Microsoft Fix It tool for 'Automatically diagnose and fix Windows audio playback problems'. This tool will check the settings, drivers, and services to make sure that it is running correctly, and try to fix any issues. Please follow through these steps to run the tool, click on the green Run now button > click Save > open the download > click Run. What was the outcome of the tool, are you still experiencing the same issue with the sound?
If you are still experiencing the sound issue after the above troubleshooting steps, please let me know exactly what is happening with your sound. (ie, no sound, sound is choppy, or distorted). Does the sound issue occur in multiple programs, or just one? (ie. Windows Media Player, YouTube, or CD/DVD).
Looking forward to working with you!

No keypad sound after update the software into 10.3.1.1565

Hi guys..please help me. I'm using Z10, after update the software into 10.3.1.1565, there is no sound of the keypad, eventhough i have made the volume of the keypad sound to the maximum.
Is anyone has any idea or suggestion about it? Thank you.

Lots of users are complaining about issues with Contacts from OS 10.3.1 udpdate (Q10 v5).
I've tried everything under the sun (reinstalled OS multiple times, completely wiped my device, etc) and the problems still persist.
I've noticed that if I repeatedly disable and re-enable Contact syncing via Settings (and then waiting an hour or two), the Contacts will eventually appear after about 5-10 attempts, and my text messages and phone calls will show names again.
BUT, as soon as my Q10 soft resets for any reason (if battery dies, for example), all of my main Contacts completely disappear. Then I have to repeat the steps above every time.
There are a few other things I've noticed:
1) If I click "Edit Contact Folder Settings" button in Account Settings, it shows Contacts, LinkedIn AND "LinkedIn 2". I don't even have LinkedIn installed!
2) If I turn OFF the toggle switch to "Sync All Contact Folders" then click save, it doesn't actually save my settings (usually if something saves successfully, the devices seems to think for a few seconds, which doesn't happen). As soon as I go back to manually edit the Contact folders, the settings are reverted back to All Contacts.
So frustrating..

HP Elitebook 8560p driver update error: IDT High Definition (HD) Audio Driver

Hi there,
Hoping someone can help..
So I tried updating/installing the latest IDT Audio driver for my Elitebook 8560p, but get this error each time:
I'm pretty sure this is because I stupidly uninstalled IDT soon after getting the laptop.. I did this because I use a seperate audio interface for recording music and didn't want any conflicts. I didn't realize uninstalling this would disable the internal audio entirely (and irreversibly it seems)! My audio still works when I connect my external audio interface, but this is quite annoying as I have to bring the interface with me everywhere, like I can't just watch a Youtube video and listen through internal speaker OR headphone output..I have to hook it up to my interface each time..urgh. My own fault I know, but I would have thought this driver installation package would work and put it back on my system..
FYI, I'm running Windows 7 Home Premium 64bit.
I remember reading a thread about this eact same problem ages ago, someone had done the same thing and was having the same problem re-enabling//re-installing it. I think he managed to find a fix that worked for him that involved removing the battery and holding the power button for 30 seconds, or something along those lines.. I remember trying that method by copying his instructions step-by-step, but it didn't work for me
Anyone else, or any HP tech support know any kind of fix for this? Fingers crosed.
Many thanks for any help or advice in advance!
Lauren

Error 52 for the IDT High Definition Audio Codec

The audio on my HP Pavilion g7-1219wm Notebook PC had stopped working. I had tried several things to fix it, even the restoration, which had worked last night but then had the same problem this morning. Please help.

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/sp52501-53000/sp52666.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, restart the notebook and let Windows fully load. 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.
If you still have no audio, open windows Control Panel, open Administrative Tools and open Services. Check that the following services are all showing as Status= Started and Start-up Type= Automatic
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type', select Automatic and click Apply to save the change. Then click the Start button.

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!

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.

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

When this has completed, right click the speaker icon in the Taskbar and select Playback Devices.
