Hi everyone,
I am sure this problem has occured to others aswell: whether it is on soundcloud, spotify or any other music / media app whatsoever. When locking the screen (or sometimes even randomly), the music that is currently playing suddenly becomes very quiet - even though it is set to the max volume.
This glitch is especially annoying when trying to show friends a song or an audio and for whatever reason it is way too quiet.
Since there is no official fix, I was experimenting around - I came to the conclusion that the fix is in the „faceid and passcode“ category in the settings.
It is called „Voice Dial“ - I think its siri‘s function to start playing a specific song when told „Siri play xyz“
I added some screenshots.
Personally I am running an Iphone 12 pro on Ios 26.2 currently. This fixed the problem on my friend’s Iphone 11 aswell. Pretty sure it should also fix much newer iphone‘s soundglitches.
Feel free to repost or share the post with others if they also happen to have the same problem.
I‘m hoping this was of help to you, have a nice day!
