Windows 8.1 IDT High Definition Audio Codecfor P7-1421 Driver Missing

I installed Windows 8.1 on my P7-1421 Pavilion desktop PC on Thursday and now have no sound. A phone call to HP customer support was unsuccessful in solving my problem, as the rep said HP has no Windows 8.1 IDT High Definition Audio Codec driver for my machine. Does anyone know if there's a Windows 8.1 audio driver for my PC or if I have a solution other than going back to Windows 8?
Thank you!
This question was solved.

You're most welcome.
Sorry that didn't work either.
Did you try auto updating the driver from the device in the device manager?
See this thread where another forum member stated he upgraded his PC to W8.1 with the IDT audio chip and he got the driver from Microsoft.

If that doesn't work...
Just for kicks, see if this generic W7 driver one from Intel works...

If not, then I guess you'll have to wait as you said, until a driver is released for W8.1.

IDT High Definition Audio CODEC - Enchancements tab missing

Hello,
So I just downloaded a driver updater and updated all my drivers. My sound used to work completely perfect, but after updating and restarting my computer the sound got all weird as the enchancement tab is gone and I don't know how to get it back. I know I might have to degrade my driver, but I can't seem to find one that supports my computer or whatever.
That's my current driver details( I think(?) ) and I wonder if anyone got any solution for this?
Also, I don't know if it matters, but I have a Razer Tiamat 7.1 headset.
Thank you for any help.

Hello @iCatNip,
Thank you for the updated information on your issue. I am going to recommend that you follow the HP Support document: Using Recovery Manager to Restore Software and Drivers (Windows 7), which will re-install the original drivers that came with your computer. I advise you use it to re-install the original audio drivers for your computer. This should give you back the driver you are looking for as this is the one that came with your computer.
Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!

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?

Idt high definition audio CODEC error (39)

HP Pavilion dv4 Notebook PC - operating on Windows Vista Home Premium (32 bit)
HP support assistant reads:
IDT High Definition Audio CODEC - Error (39) - Driver stwrt64.sys - version 6.10.6047.5
Recently uninstalled and reinstalled itunes and now when i open it says "itunes has detected a problem with your audio configuration" and wont play songs

Thanks billaboard for your response.
Unfortunately, I gave up waiting for an answer and just re-set the laptop back to factory specs.... then spent the next 8 hours re-installing programs & updating windows & the HP programs to the current versions.
I won't be using an NCH product again.
In terms of who I should be asking, I would point out:
I used the inbuilt HP Support Assistant on my laptop, to diagnose why my sound wasn't working. It identified the drivers that were at issue.
I uninstalled all NCH programs
I downloaded the correct HP Audio drivers & reinstalled them. They advised it was a successful install. 8 times.
Each time I rebooted, I would run the HP Support Assistant again and it would then identify that the HP drivers were not working.
The HP Support Assistant link, for further help, led me here. If this isn't the correct place to ask for help.... a site labelled "HP Support Forum", then where the hell is ?
Thankyou again for your response. If I have further issues with other programs, I will follow your advise and re-install the offending program, before un-installing.

Windows 8.1 Pro 64 bits. Problem with IDT High Definition Audio Driver on my HP pavilion g6 notebook

Hi!
I'd recently upgraded from Windows 7 to Windows 8.1 Pro 64-bit version. All drivers worked fine but I'm having problems with IDT High Definition Audio driver. Can someone help me? Thanks in advance! My PC model is: LS278EA#ABE

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

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.

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.

No Sound after updating IDT High Definition Audio Codec on my HP Pavilion dv6-6154tx laptop

I recently ran Advanced Driver Update to check and updated my audio driver (IDT High Definition Audio Codec) on my Windows 7 laptop. However, after the update, every time I boot up the computer, there is no audio output. I checked the volume control options and they are all fine, showing "all devices are playing sound". But there is no sound. Even the 'test sound' option does not play any audio, although the computer says that it is working fine. I read some posts on this forum and came across an answer - to uninstall the current driver from Device Manager, and manually install IDT HD Audio Driver for Windows. This works and I am able to get back the sound. However, I have to do this every time I start my computer after shutting it down, and this is proving cumbersome. Can somebody please help me with this and suggest a solution? Thanks.
