Please make sure its not a hardware / physical problem... such as dust inside the mic hole, or a faulty mic.
I could give a modded acoustic profile to increase mic volume... BUT, I would search Sony support in first place. And use a modded acoustic in last place.. since a low volume mic is not normal... I never had any complain about volume,
But quality is another story, and it depend mostly on Service Provide quality
