Please reboot, and if trouble persists and you're on a MacOS device:
- Click the Apple icon in the top-left corner of your screen, then
System Settings → Notifications and ensure Allow notifications when mirroring or sharing the display is switched on — like this: https://slack-files.com/T12KS1G65-F05FCGPFF1R-e6e1e9987b
- Click
Sound in the left column and ensure Play user interface sound effects is on — like this: https://slack-files.com/T12KS1G65-F05FCL9F4LA-d5aee1e479
- Lastly, press and hold
Fn on your keyboard, and press cto open the Control Center — if a Focus mode like Do Not Disturb is enabled, please disable it
If those steps don't help, share 3 screenshots so we can investigate:
- Click the Apple icon , then
System Settings → Notifications, and capture a screenshot of the top half of the Notifications menu — attach it to your reply
- Click the Apple icon , then
System Settings → Sound, capture a screenshot of the complete Sound menu (top to bottom), and attach it to your reply
- Press
Fn + c, then capture a screenshot of the open Control Center menu plus the menu bar atop your screen, and include it in your reply; here's an example: https://slack-files.com/T12KS1G65-F05FCCDL5NF-8f44ff9cf5
