HP dv9728cl need windows xp driver for Conexant high Definiation SmartAudio 221

I was downgrade HP dv9728cl from Visat to WinXP, many drivers are missed. Right now, i am working on the sound card. I have installed the MS UAA sp33876.exe and try several conexant HD smartaudio 221 but failed. It usually said that there is no such hardware. If I can to install the driver manully, there is no inf file in the direction: SWSEUP\SP33566, SP33571, SP33867, SP34200 or SP37858.
By the way, I can only find the models "NOAUDIO.DeviceDesc, Ripitide Audio device, Riptide Bus/Firmware downloader, Riptid Gameport Riptide Input Device" for Conexant when I try to mannually update the drivers for " sound, vedio and game controller "

Thanks a lot!

    Thanks a lot for your quickly response. I can hear the sound while the mic doesn't work. I will try your sugguestion to see whether the mic can work.

    Unfortunately, the mic doesn't work with that UAA and Audio driver.

    Currently, I use the following UAA and audio driver. I really appreciate if someone have some idea for the mic issue.

    Anthoer issue is that "OHCI Compliant IEEE 1394 Host Controller" gets the yellow question marker.

    Note: It is strongly recomended to install this driver before you install the audio driver. If you do not install this driver the audio will not work.

I understand that you have downgraded the operating system from Vista to XP and you are unable to install Audio drivers in your Notebook.

To isolate the issue please install following UAA drivers and Audio drivers.

Here is the weblink to install UAA drivers.

Please do not click on the link. Copy and paste it in a new Internet Explorer window.

After installing UAA drivers restart the Notebook and then install Audio drivers.

Here is the weblink to install Audio drivers.

After installing Audio drivers restart the Notebook again to get the changes effect.

I hope this will work.

    For "OHCI Compliant IEEE 1394 Host Controller" install Chipset drivers and restart the Notebook to get the changes effect.

    If you wish I will provide you the chipset drivers . But, to provide you the exact chipset drivers I need product number of your Notebook.

I need a conexant smartaudio 221 driver for windows 7

Have you been to the Compaq/HP website to check your specific model for updated Windows 8 drivers? It's tough to know for sure...but "Base System Device" and "Coprocessor" are possibly parts of the motherboard chipset..and the SmartAudio 221 component is also likely built in to the motherboard. I would do a search on the HP/Compaq website, and possibly find the right drivers using their support may identify them based on your serial number. Make sure they have Windows 8 compatibility. If not, you may want to go back to 7 for a while until all the drivers can be updated for 8.

Where can i get drivers for my Compaq Presario CQ50? I downgrade it from Windows Vista to Windows XP Home Edition. Thank you so much for your help.

Downgrading from Vista to XP is not a good choice. Specially HP Notebooks are not comaptible with retail version operating systems and its difficult to find the drivers and get it work.

I found a few. Please install in the same sequence and check. A restart is must after each driver installation.

1. Here is the link to download Intel Chipset Installation Utility for ICH9:

2. Here is the link to download Mobile Intel 4 Series Express Chipset Family Graphics Driver:
It's always recommended to install UAA drievr, before installing Audio driver.

Xp driver for laptop conextant smart audio 221

Recently I had to reload the XP sound drivers on a hp compaq 733TU laptop. I have tackled this a coupleof years back but had forgotten the problematic task. Many drivers appear to work but with microphone issues. There is a Lenovo Conexant smart audio 221 driver that does do the job correctly after modifying the .inf file contained within the driver. The driver is labelled 6ea114ww.exe from here Using an extraction tool like winrar the 6ea114ww.exe file can be unpacked and the file TPUNHER5.inf can be updated using notepad to include your device id string from device manager.
