Audio Connection Problem with HTC P3600

[crachedi]

If somebody can help me analyze the problem I have with my HTC P3600, It would be very helpfull.
Since 1 week I can not get the audio out from the phone internal speaker (ear speaker).
When I connect a simple USB Headset it is working OK (I get the audio), when I switch to the loud speaker it works OK. But as soon as I come back to normal mode (ear speaker) It does not work any more.
I reloaded Radio ROM and FAMAN ROM Version 4.2 but no change.
Any other suggestion ?

Thanks

BY the way this is my current Software version:
OS ROM: FAMAN 4.04 FR
RADIO ROM: 1.50.08.11

I have the same problem. My Htc p3600 works correctly in alimentation way but in normal way no audio (ear and tone) is present. is it possible that a old battery can be the problem?
