C100 awful noise during a call

[extremum]

C100 works ok until call is made. After connection there's a real loud noise from speaker until hang up. It's not mic interference, same thing without mic. I tried to rehot the components on pcb that are not on compound and did E2P custom reset, it worked for ~30min and turned back. Any suggestions?
