Error sound when doing Alt +/- adjustments

Question

It's working as intended but it's doing a beep sound.Any possible solution other than muting the volume of the PC or muting the beep sound in control panel? Lightroom version 14.3.1Windows 11

This is caused by Windows and LR not playing nicely together in the sandbox.

On Windows, you can invoke program menus using the Alt key followed by additional keystrokes. For example, in LR, Alt F E opens the File menu and then invokes the Export menu item. In general, when you hold down the Alt key, the letter that opens a menu item is underlined.

LR has assigned many shortcuts that are Alt + <letter or number>. But when you use that shortcut, Windows beeps at you, because it thinks you're trying to type a menu accelerator that doesn't exist. E.g. when you type Alt = to adjust a slider, Windows sees there is no menu accelerator for Alt =, so it nags you with a beep.

I don't know if it's possible for an app like LR to tell Windows to shut up when there is a valid keyboard shortcut starting with Alt. I'm pretty sure that Adobe considers this LR behavior "as designed".

Issue: Using Alt key for fine slider adjustments works in Windows, but gives system error sound.

1) Open Lightroom, select a photo and go into Develop mode.
2) Click on "Exposure" in the Develop Module and click the "+" key, the exposure goes up by 0.1, as expected.
3) Click the "Alt" key and then "+". The title "Tone" changes to "Reset Tone", a Windows warning sounds and the exposure is increased 0.02. The Windows warning sound is unexpected. Could the warning sound please be removed when using the Alt key for fine grained slider adjustments.

(There is a workaround, which is less than idea. To stop the Windows warning sounds, go to Sound, Open Volume Mixer and mute "System Sounds". There will be no warning sound when using the Alt key. However the users needs to remember to re-enable System sounds after using Lightroom).
