Turn Delete Sound On or Off auf Xiaomi
On MIUI, deleting a message, file, or notification triggers a short confirmation sound by default. This feedback tone is a system-level setting, not something controlled inside individual apps like Messages or Files.
Because it lives in the general sound settings, turning it off (or back on) affects the delete sound everywhere on the phone, not just in one app.
Where to find the setting
Open Tap on Settings ➔ Tap on Sound & vibration ➔ Tap on Additional settings. There you find the toggle to Enable or disable Delete sound.
Switch it off if you want silent deletions. Switch it back on if you rely on the sound as confirmation that an action went through, for example when deleting several files in a row without looking at the screen.
When to leave it on
If you often delete items in low-light situations or without checking the screen each time, the sound acts as useful feedback. In quiet environments like meetings or at night, turning it off avoids unwanted attention.
This setting does not affect other system sounds such as keyboard clicks or screenshot sounds, which are toggled separately in the same Additional settings menu.
