We'll focus on this part:
Multimedia:
Conexant audio card Cx20561 @ Intel 82801IB ICH9 - High Definition Audio Controller [A-3]
Intel HDMI Audio Card @ Intel 82801IB ICH9 - High Definition Audio Controller [A-3]


In this case, it is a Conexant Cx20561 audio chipset .

2. Download the Conexant driver


Here are the XP drivers for these models:
You can try to install the driver directly, but most of the time it does not work.

3. The identification number of the audio chipset

  • Open the Device Manager (Start> Run> Type "devmgmt.msc" and confirm with OK). Normally, under "Other Devices", you should the have Audio Device - High Definition
  • Audio Bus with a yellow question mark in front.
  • Right click on this entry and choose Properties.
  • Choose Details and retrieve the identification number of the device.

Taking the PC Compaq Presario CQ60 as an example, the identification number of the audio chipset is:
  • HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_103C360B

4. Editing the audio driver


The Conexant driver is downloaded as an archive. Extract it.
We'll have to edit one of the extracted files (Right click on the file> Open with Notepad):
  • For Conexant Cx20561 it is the TE1HER5a.inf file.
  • For Conexant CX20549 it is the CpV30D5a.inf file.
  • For Conexant CX20551 it is the BD1HDAa.inf file.


Taking the audio Cx20561 Conexant chipset as an example, edit the TE1HER5a.inf file:

%HdAudioFunctionDriver.Hermosa5051.DeviceDesc% = HdAudModel,HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_1179FF5F
  • Thus the following line
    • %HdAudioFunctionDriver.Hermosa5051.DeviceDesc% = HdAudModel,HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_1179FF51
  • Is modified to:
    • %HdAudioFunctionDriver.Hermosa5051.DeviceDesc% = HdAudModel,HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_103C360B
  • Save the file and run the setup file to install the driver (or install the driver manually).
