sub-woofer doesn't work Dell Inspiron 7567

If you are lucky, go to Control Panel, System and Security, Backup and Restore ...and restore it to a prior date before the new driver was installed.

Think Dell will be pushing a new driver out.

To manage-turn on System Restore Points, is through Control Panel, System and Security, click System. Then click System protection on the left. 

I hope yours was turned on. By default I think it is.

Thank you for the response ... currently the restore is not much of an option for me... and yes i'm hoping that they will release new driver soon, as the previous audio driver was back in 2017

After the new Realtek update, the subwoofer does not work at all and it's give crackling sound. Problems are resolved when I install the old Realtek driver again.

You can download the old version from here:

Thank you for the reply my friend, but that didn't work as well

Here is what i did

1. Remove completely the new driver;(remove device and delete driver option)

2. Restart laptop

3. Install Driver - the moment is installed it will play the sub-woofer sound nicely 

4. Restart

5. Again the sound is bad no woofer :(

Here is what the driver says

so it clearly shows the old driver from 2017, but no sound changes :(

Let me know if missing something or making it wrong

Thnx again

From Yesterday mine also stopped working from recent update of audio driver ..  I also uninstalled drivers completely and switched back to old one but still subwoofers not working 

Since the thread is a month old, possibly the OP has corrected the problem by now.  I am running the latest audio driver available on the Dell site and the subwoofer shows normally, so not sure why some folks seem to be having a problem.

You have to keep in mind that Windows has audio drivers all over it will install, if allowed.  Since such a driver may not be compatible with the 7567 I always download the new driver and go offline until after I have the new one installed.

There is also some controversy going on with the 7567 related to Bios upgrades and those being rolled back by two versions.  The new Win 10 build release, which is currently "Paused", seems to have bumped into some problems.

This actually worked!!

Thanks bro @jmzdota

Having same problem. I reinstalled audio driver, so sound is on but sub-woofer is still not working. 

This is the 2nd time I am having sound issue on this model .

DELL service isn't on the same level as their competitors.

Hope issue will be resolved asap.

I rolled back the drivers, unistalled the windows updates, deleted the Waves Maxx files and then installed the new drivers. Nothing works

it works! thank you @vlad8marta 

//Just download and follow the installer
