IMPORTANT NOTES:

1.before using any of IDT i gave here, if you already download the IDT on my blog for your model ignore this and refer back if the driver you download earlier failed after the force method.

2. If you have the audio for the vista drivers then use that drivers, if failed through the force method then refer back to the list IDT below.

List of applicable IDT:
SP39671.exe: Download - recommended
SP45100.exe: Download

10. After open the SP39671, there 3 folder and select the wdm folder. For other audio driver maybe you will have the similar folder or different, Important to remember we a re looking for files ended with INF extension.

Compaq Presario V2414NR Windows 7 Sound Driver

Your Audio is:
Conexant CX20468-31 AC97

to install the driver there are some method you need to do.
note: just try to update driver manually by:

- Opened device manager (right click on my computer and select manage, search for device manager at the left)
- Right click - On the audio(with yellow mark) right click and select Update Driver Software
- select no to search online, select manually install driver, select dont search i will choose the driver to install adn next browse to c:\swsetup\sp30399
- Clicked Next

IF THE METHOD ABOVE DIDN'T WORK, FOLLOW THIS STEPS:

1. Download driver sp30399! You can get it from here: Download

2. Run the exe

3. Go to the extraction folder (Default: c:\SWSetup\SP30399)

4. Edit qta3091.inf:
Search code block:
[Conexant]
%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,PCI\VEN_1002&DEV_4370&SUBSYS_3091103C

and add this line under:
%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,PCI\VEN_10B9&DEV_5451&SUBSYS_0024103C&REV_02

So the result would look like this:
[Conexant]
%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,PCI\VEN_1002&DEV_4370&SUBSYS_3091103C
%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,PCI\VEN_10B9&DEV_5451&SUBSYS_0024103C&REV_02

Attention! I've copied this part from the device manager:
"PCI\VEN_10B9&DEV_5451&SUBSYS_0024103C&REV_02"

You may have a different device description. If you wanna be sure, go to the device manager, open the unrecognized audio device's property page, select "Details" tab, and select "Hardware Ids" from the Property combo! Copy any of the listed strings and replace it with my device description!

So the final result would look like this (if you have different device desc.):
[Conexant]
%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,PCI\VEN_1002&DEV_4370&SUBSYS_3091103C
%*WDM_AMCAUD.DeviceDesc%=WDM_AMCAUD,HERE COMES YOUR DEVICE DESCRIPTION
5. Now all you have to do is to install the driver manually through device manager like the first method i posted above with blue font

General sound driver for compaq

I created this post to cover the failure of sound installation for Compaq Laptop after downgrade to XP. This post basically for Compaq Presario CQ35-216TU and since this post is still new, you feedback are important.

List of MS-UAA available:

note:
--please install netframework before MS-UAA----------------
.Net Framework:
http://tinyurl.com/758p8
most driver built for windows XP SP2, so it strongly recommended to update your windows by downlod and installing SP2 patch from microsoft.

MS UAA (alternative to sp33867)
http://www.mediafire.com/?4ben9zlesng

MS UAA for XP SP3
http://couponmeister.com/blog/HD_Audio/KB835221.exe

Notes: MS-UAA require before installing sound driver.


VERSION 1
==============
1. Conexant High-Definition SmartAudio 221 Driver

Driver modded by silver here: http://www.mediafire.com/?dg0cmmkm4y4

Unzip to a folder..use Device Manager,right click "Audio Device on HD",choose Update driver,
No to connect,
Install from a list or specific location,
Select Don't Search, I will choose the driver to install,
For the Hardware Type select 'Show All Devices'
Remove the check from "Show Compatible Hardware" and click on "Have Disk".
Next...browse to the unzipped folder and choose the "WiSVHe5.inf".
Ignore XP when it complains.
Reboot.

A new version of Conexant HD SmartAudio 221

Modded driver from Toshiba driver (tested good in dv2922tx, however some users reported it was not working for their notebooks)

-------------------------------------------------------

VERSION 2: IDT-hidh definition audio codecs

MS-UAA HERE

Some notes:

1. If your model use Intel video graphic, MS-UAA must be installed before Intel video graphic driver.
2. New Nvidia drivers (185.85) also required MS-UAA for HDMI driver
3. A reboot is required before installing Audio and Modem drivers.
4. MS-UAA, sp33867, mainly is kb888111 with other Quick Fix Engineering (QFE) for XP
5. If you are using XP-SP3 (not recommended for the first trial), try using kb835221 (older version of MS-UAA) or do the registry edits as supplied.

Sound driver

Please make sure MS-UAA has been installed properly

How?

Go to Device Manager under System Devices to see if MS UAA installed properly.
There should be a listing for Microsoft UAA Bus Driver for High Definition Audio.
If not, you should have a PCI with yellow!.
Right click it and Update Driver,
No to Connect, No to Search and last Install Automatically.

ADDITIONAL NOTES:

SOUND DISSAPEAR AFTER RESTART:
------------------------------------------------------------
1. Try using this ms-uaa:
ftp://ftp.hp.com/pub/softpaq/sp42001-42500/sp42126.exe
-------------------------------------------------------------

2- Using devcon:
If you found the sound was not working after restart, do the following steps

1. Download devcon command line utility,
http://support.microsoft.com/kb/311272

2. Extract and copy the file to c:\windows\devcon\i386\devcon.exe

3. Make command line to restart MS-UAA automatically or just download this file
http://www.mediafire.com/?jykjgmnjjcn

The command line as: C:\windows\devcon\i386\devcon.exe restart "PCI\VEN_8086&DEV_293E&SUBSYS_3607103C&REV_03"


Notes:

1. The location of devcon.exe is in c:\windows\devcon\i386\devcon.exe if you change it, you need to edit idt.bat

2. "PCI\VEN_8086&DEV_293E&SUBSYS_3607103C&REV_03" is hardware ID for MS-UAA, if you found it in a different name change it.

3. Place idt.bat in c:\Documents and Settings\All Users\Start Menu\Programs\Startup

4. The sound will be restore within 6-10 seconds, because of that there is NO sound of XP start-up
(note: if this method failed, remove devcon utilities)
---------------------------------------------------------------------------------------------

3. Downgrade/upgrade BIOS.

this option for advace user only:
