Timer doesn't sound if set to same interval as screen lock.
Original post (iPhone Timer doesn't sound if period is s… - Apple Community) was locked due to inactivity, but I still have the same issue in October 2022 with iOS 15.6.1.
Note the the response to the original post suggests restarting the phone. That works for me for a few minutes, but the problem recurs after a few minutes every time. How can I fix this permanently?

If I set a timer on my iPhone for the same time interval as my
"Auto-Lock" Display setting, and then I don't touch the phone during
that period, the timer will not sound, or the sound will be cut off
almost immediately. For example, I have Auto-Lock set to 5 minutes. If I
set a timer for 5 minutes and leave the phone alone for that time, the
timer expires without the phone making any sound at all. A timer set for
4 or 6 minutes works correctly. This started happening several months
ago, and it happens every time now. How can I fix this?
