problem with handsfree & microphone

Hi Guys,

I have Iphone 5 that faced problem with hands-free and loud microphone . (both working very very bad)

i replaced this part ( Dock Connector) to fix this issue, now microphone and hands-free voice works but , hands-free voice not clear at all .

I can't hear music and calls clear with hands-free ?!

(microphone works good now, hands-free not clear ex. == hearing music == )

Any suggestions how to fix it ?
