Oct 14, 2012 XPS420 sound card driver by steve0526 / October 12, 2012 7:23 AM PDT I need to update the driver for my sound card. Just view this page, you can through the table list download Dell XPS 420 drivers for Windows 10, 8, 7, Vista and XP you want. Here you can update Dell drivers and other drivers. Here you can update Dell drivers and other drivers. Nov 27, 2010 This particular xps 420 has an nVidia chipset, and the driver that windows update tries to install if you allow it is the wrong video driver, which (for me at least) caused a driver conflict with the elusive fifth HDMI sound driver (your speakers).

Kevin Shroff's Modded Realtek Drivers (KSMRD v1) Release: 7-17-17, based on Dell Realtek Driver 6.0.1.8105
About:Jpeg download for windows 10. This modded Realtek Audio driver disables the heavy post-processing sound effects from the stock Dell driver to allow for a clean, neutral, and flat audio experience. This is achieved by disabling Waves MaxxAudio throughout the driver, thus leaving intact only the essential core Realtek audio software.
Waves Maxxaudio is immutable bloatware that is shipped with all modern Dell XPS systems. It is inherently flawed as it heavily manipulates any and all audio output, making it impossible to accurately produce or listen to music, and overall degrades the entire aural experience on any machine that it is present on.
As Waves MaxxAudio is part of the Audio driver of Dell XPS systems, it was otherwise impossible to disable just MaxxAudio and its processing effects - even when MaxxAudio is turned off in its application's GUI, post-processing STILL occurs on any and all audio output. The only other alternative was to use the Microsoft default Windows High Definition Audio driver, but this driver has many problems on Dell XPS machines - it causes random loud pops and crackles, especially during usage with ASIO software (in my experience).
My modded driver solves these problems as it uses the original Dell driver as a base (which has no pop/crackle problems), and additionally disables all post-processing and provides flat, clean audio playback just like the Windows High Definition Audio driver, but without its bugs. This driver also has some additional advantages:
Completely flat & clean audio experience: no post-processing
No extra, unalterable Waves MaxxAudio bloatware (the driver doesn't even install it!)
Reduced power consumption compared to stock Dell Realtek Audio drivers - as there is no post-processing constantly going on with all audio, this may lead to increased battery life
No stupid GUI popups for Input/Output switcher (The prompt 'What did you just plugin: Headphone/Speaker/Microphone' does not popup anymore)
Can prevent laptop speaker damage - some people had concerns that the Waves MaxxAudio software was pushing the XPS laptop speakers too hard, causing early speaker damage. As Waves MaxxAudio and its sound effects are removed, this concern should not be an issue with this driver.
Disable Secure Boot: Secure Boot must be disabled in the BIOS/UEFI of your computer. This is required to install the driver, as this modded driver is not signed. After driver installation Secure Boot will be re-enabled in later steps
Run Command Prompt with Administrator privileges, then run the following commands, pressing enter after each: bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS bcdedit.exe -set TESTSIGNING ON
Reboot
Uninstall 'Realtek High Definition Audio' from Control Panel, and uninstall 'Realtek Audio' from Device Manager - do not reboot!
Install Driver Sweeper: Driver Sweeper @ Mega and select Realtek - Sound, and then click clean - do not reboot!
Navigate to where you extracted my driver zip download, and open the 'RealtekHDAudio' folder. Run 'Setup.exe' inside of it and install the driver just like a normal Realtek Audio driver.
You will get a popup that asks if the driver is safe and should be installed - click 'Yes, install this driver' (or something along those lines) - this popup comes up only because the driver signature is not signed, as it is modified. Driver itself is safe and you can scan it with Antivirus for assurance.
After the installation is done, reboot
Run Command Prompt with Administrator privileges, then run the following commands, pressing enter after each: bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS bcdedit.exe -set TESTSIGNING OFF
Boot back into your BIOS/UEFI and turn back on Secure Boot
The testsigning watermark (some text in the corner of your screen, on your wallpaper) should be gone now. If it is not gone, run step 7 again and reboot, then continue to step 10
Open task manager, go to startup tab, and disable both 'HD Audio Background Process' and 'Realtek HD Audio Manager', and reboot.
Optional: Install EqualizerAPO or Viper4Windows (do not install both!) application to be able to add & control sound effects, or boost volume.
Note: Clicking on the Sound icon in Windows will always show as 'Speakers (Realtek Audio)' however this is just cosmetic. Audio is properly routed and works with both headphones and speakers correctly and as expected.

Uninstall my driver from control panel & device manager, and reinstall any driver of your choosing (Dell Audio Stock drivers, Windows default drivers)
PS: I know some of you are still waiting on that XPS 15 9560 NVIDIA GPU Undervolt tutorial I had promised - some university stuff came up and I was unable to do so. I'll try my best to do that video and release it ASAP. Thanks and enjoy the driver!
