keyboard typing sound

so today suddenly my keyboard sound became low on my iphone 15 plus even though the rest of the system volume was on high, i even tried going to Sounds & Haptics turning on and off the keyboard sound and the issue was still there, but this issue is not there when I connect my earphones without the earphones the keyboard typing sound is negligible. Also the rest of the sounds like notifications, music and videos everything is working normal apart from my keyboard typing sound. I even tried turning on and off the DND button but it still didn't get fixed.
