People using Dell computers sometimes face an issue where they might find that the
Soundmax HD sound card
is unable to
activate sound mix
. To get around this problem the user would need to download audio driver from the official Dell website. After that, one needs to open the
ADIHDAUD.inf file in a text file
and make some changes at specific lines. After that one must uninstall the old driver and install the modified driver. The user may install the new driver by running
setup.exe or via Device Manager
to get the
Soundmax HD sound card
up and running.
[Dell] Enabling Stereo Mix with SoundMAX
There is a recurring issue on the Dell PC with a Soundmax HD
, you can't activate stereo mix. Quite annoying when using the recording software such as Audacity.
Changing the audio file
Download your audio driver on the Dell Support Site => Here
Unzip your driver into a new folder (e.g call it "dell_driver")
In the folder search for ADIHDAUD.inf
Open the ADIHDAUD.inf file with a text editor (Notepad)
Search the following lines:
HKR, AD1983 \ \ Désactiver, les activités de sensibilisation, 1, 01
HKR, AD1983 \ \ Désactiver, MonR, 1, 01
HKR, AD1984 \ \ Désactiver, MonR, 1, 01
Change the value (01) on each of these lines by 00, which gives:
HKR, AD1983 \ \ Désactiver, les activités de sensibilisation, 1, 00
HKR, AD1983 \ \ Désactiver, MonR, 1, 00
HKR, AD1984 \ \ Désactiver, MonR, 1, 00
Changing these values will normally show the stereo mix option of your sound card after installing the driver.
Once "ADIHDAUD.inf" is modified, we must uninstall the old audio driver.
Go to device manager (start>run>devmgmt.msc)
Select the driver for the"Soundmax" sound card in "Sound, video and game controllers"
Right-click on it: "Uninstall", then restart the PC
During startup, if it is proposed to install the audio driver (new hardware), click "Cancel".
To install the modified driver:
Go to the "dell_driver" folder and run "Setup.exe"
Once the driver installation is complete, restart the PC.
Second solution (if the first one failed):
Go to device manager
In "Sound, video and game controllers", a yellow-type "?" or "!" shall be present
Right-click and select: "Update Driver".
Then select = "No, not this time", then click "Next."
Choose "Install from a list" then click "Next."
Click "Browse" and select the "ADIHDAUD_inf" file
Click "Next" and the driver should be installed.
Restart the PC
