The loudest ringer setting on the phone is too soft

I fear this is a hardware issue. Even with the volume set all the way to five (as high as it goes on my A650) The loudest setting is not very loud. That not only applies to all my downloaded midi files (which I tried to turn up using both PSPlayer and Anvil..they still aren't loud enoughh)..but also the preset ringers are too quiet. IS my phone's volume setting faulty? Is it impossible to define the "high" setting as louder than it is?? The high setting is soft and the low setting I wouldn't know was ringing unless I had my face on the telephone. Can this be adjusted in the phone itself? IS there some secret menu that lets turn up the sound?Thanks
