Speaker (earphone) problem topic

It looks like I've got a problem with my earpiece. It's not loud enough and I think it was louder before. I don't remember exactly when it became so silent but it was not too long ago, I guess after some flashing. It's silent on every ROM now, CM11, CM12, ARTMOD, Sling, Now I use official just rooted and it is also silent.
Is there any help for that or the earpice is broken and I should send my phone to warranty?
