How to adjust Bass and Treble in Windows 11?

Thank you, that's good information that a half dozen contacts with Microsoft- none knew that. As I wrote earlier, I solved my problem by getting a third-party app that installed easily and works great.

That Microsoft or Dell hide or choose to not provide an equalizer is a big disservice in my view. Folks like me with hearing loss in multiple ranges can make adjustments that make music enjoyable again. Shame neither company sees it that way- I've written to both. Crickets...

There is a technical reason why the EQ "disappear".

If they give you multiple EQ, people will mistakenly enable multiple EQ at the same time and ruin their sound.

Even 10 years ago, the old "audio enhancements tab" bass boost or equalizer only appears if you use Microsoft's generic audio driver ("high definition audio device"). When you install your computer's specific audio chipset driver (such as Realtek), then the bass boost in the audio enhancements tab should disappear because you now have the EQ in the old Realtek HD audio manager. Even in Windows 7, if you have a computer model with premium audio package (such as THX and Soundblaster), the EQ in the Realtek HD audio manager disappeared.

Your sound would get all muddy if you enabled the bass boost in the enhancements tab and the EQ in the Realtek HD audio manager at the same time because you forgot that you clicked the bass boost button 6 months ago and now you are fiddling with the Realtek EQ. So the only sensible thing to do is to delete 1 of the EQ.

There can only be 1 EQ in your whole computer and that may be a traditional 10 band EQ or some smart pre-sets.

You have an HP computer, then you either have HP audio app or B&O audio app. And if you have a premium audio package on your hp computer, then you have additional auido apps.

Whay third party app did you get?

FxSound

Both of you don't say enough information that matters to give you advice.

Go through the following:

1. I have Realtek Audio Console app (SouthBay has a HP computer so he has HP audio app or B&O audio app) and it has an EQ --- then use that EQ, no need to download FX sound.
2. I have Realtek Audio Console app and it doesn't have EQ, but in addition to the Realtek Audio Console app, my computer also has Creative Soundblaster Cinema app and that has an EQ --- then use that EQ and no need to download FX sound.
3. I have Realtek Audio Console app and it doesn't have EQ. I also have DTS app but it doesn't have an EQ. The DTS app has a bunch of smart pre-sets and they work ok enough. I don't have to download FX sound. And for SouthBay, if these smart pre-sets are good enough then he can uninstall his FX sound app.
4. I have Realtek Audio Console app and it doesn't have EQ I also have DTS app but it also doesn't have EQ. I don't like the DTS smart pre-set EQ's. Then go and download FX sound or Equalizer APO.
