Re: "was just bought an iPad Pro M4 from Dec 2024, and around this 1 month,
if I play games then sounds will suddenly disappeared while i’m playing. It makes me very uncomfortable:( "
Wondering if something you do while playing is turning off the sound accidentally.
Eg: Unknowingly triggering a shortcut that turns the sound off, or "mutes'" it
Check if turning the sound back on, or unmuting, will fix it.
If so, next time it happens : try to notice what you did just before the sound stopped.
Else: you may accidentally turn the volume right down .... seems like sound is off because volume too low.
the volume buttons are generally on the top or the side of an iPad .
Eg: Check if adjusting the volume will fix it.
If so, try to see how the volume was changed
iPad also has a "silent" mode ... It could be activated unintentionally.
you can check if it is on or off, and change it, in Control Centre
If needed: Restarting your iPad can often restore order : see: Restart your iPad - Apple Support
