I have a problem with the build in speakers on my Samsung galaxy. They only work while in a call (I can hear the other person talking). For everything else they are mute. Can you tell me is it a hardware problem or something else? I checked and the volume is set on MAX, phone is not on mute. Also, as far as I know, the phone is not on a custom rom and it might be rooted (not sure because I haven't rooted it but under the kernel version it says: 18.104.22.168-perfroot) When I first got the phone everything worked fine.
