I got this phone 3 months back with ICS installed in it in Europe.
i had the issue 2 times now, no sound would play that is supposed to come through the speak e.g speaker phone etc. The first time, pushing the phone volume button to max while on call fixed the sound.
Today, though the trick with volumne did not work, also reboot 2 times did not help. then i decided to lightly pinch the frame just on top of the speaker and the sound started coming although only while i was pinching. it took me a few attempts with different pressure levels before the sound could be permanent on without pinching.
Seems to be hardware issue. anyone having similar experience?
Try the app named SoundAbout from the Google Play store. It may help it the loose connection is confusing the phone.

Found another post about someone doing a hardware fix themselves. You have to scroll down.
