XPS 9520 Sound volume too low

XPS 15 9520

Windows 10:

Once windows installed it automatically installs "Realtek® Audio" driver ver. 6.0.9285.1. It does not matter where you move the volume slider it always plays sound at 100% volume and it's very loud. Using Dell Command Update I upgraded audio driver to the latest available version 6.0.9369.1. I am able to choose volume I want, but when I select 100% it play sounds at 50% of volume it was before I updated the driver. And it's really quiet. Uninstalling the latest driver gives 100% of loudness again without any options to choose less volume. Installing back the latest driver gives 50% loudness when slider moved to 100%. If I slide volume to 50% I barely hear sounds.

Windows 11:

With default driver after windows was installed the sound is quiet. After using Dell Command Update I upgraded audio driver to the latest available version 6.0.9369.1 and it becomes a bit louder, but not that as it should be. For example, if you run dell UEFI diagnostics it plays sounds very loud.

I read through https://learn.microsoft.com/en-us/windows/win32/coreaudio/audio-tapered-volume-controls so, I believe, there should be an .inf file section which describes min and max voltage or idk.

Who knows how to fix it?

The weird thing is that DCU offers to install 2 Realtek driver versions. Top one is 6.0.9285.1, A00 and  6.0.9369.1, A01 below.camphoto_992951867.JPG

After installation and reboot was completed I found that even both drivers were installed currently running version is 6.0.9285.1, A00. So I manually install 6.0.9369.1, A01 which uninstalled the previous one, rebooted, installed latest one, rebooted and now I have 100% volume as it should have, loud and clear.

But Windows 10 volume issue still exist.


Experimenting with Windows 10 and different driver versions I found that all driver versions below 6.0.9285.1 give max volume without ability to adjust it. It's either 100% or 0%. I tried 6.0.9228.1 \ 6.0.9247.1 \ 6.0.9261.1 - same behavior.

Driver version 6.0.9285.1 and 6.0.9369.1 give the ability to adjust the volume but even at 100% it's quiet.

Sounds like you've already done diagnostics in BIOS and they passed. Have you done diagnostics in SupportAssist? Have you tried to update the drivers using SupportAssist instead of Dell Update or Windows update?


I tried, same result.

Installed windows 11 again. Right after installation it was High Definition driver and it was possible to change volume, but it was in "quiet" mode, like windows 10 with latest driver. After few minutes it was automatically updated to Realtek audio 6.0.9285.1 and volume became constantly max regardless slider position. Next step was to manually update through DCU to the latest 6.0.9369.1, reboot and we have nice volume and normal reaction to the slider position. Long story short, using w11 for now

But I will be glad to hear if anyone has the same problem with w10 and found how to fix it.

You cannot use the W11 driver that works properly on W10?


I can and I used. It's 6.0.9369.1. Installing it in w10 gives low volume. In w11 it gives normal volume. I mentioned this in my 2nd reply above.


That's very interesting considering people are reporting a lot of sound issues etc with W11. If you feel that you've found a solution for your problem, consider marking your message as the solution. Considering now that W11 is the new Windows sadly I don't think any care will be given to the fact that audio does not work correctly in W10.

Same problem here. The laptop's sound is too low at windows 10, maybe a bit better or windows 11 but not so loud. I hope the dell can fix it.
