Help!! Audio Bug!! topic

I just want to ask .. I encountered this problem since i always connect to sbh20 my internal speaker wont work if i play music from walkman,system audio ringtone but works in alarm? I thought its just a audio bug because diagnost apps detect my speaker and works fine. I also encounter when im connecting sbh there some change that thw internal speaker work for about a sec then it will connect to sbh20. Is there any way to fix this aside of resetting or reflashing??

Running 4.4.2 kitkat btw


Thanks in advance :)
