I cannot turn off speaker

[stiffler120]

Hi everyone. I have a problem with my Artemis. When i was trying msn on my mobile, i recorded and send an conversation on one of my msn-contacts. After this i played the recording on msn to hear what i send him. Everything worked ok. I closed msn, and tried to make a call. But all the conversation was like if i had the speaker on (but i had it off). I tried to activate it, and after this to deactivate it, but the problem was still the same.since then every time i use the device as a phone to make or receive a call the problem is the same, i hear the sounds like in speaker-on mode.
I tried Hard Reset and Soft Reset, i even tried to change ROM on my device but the problem still is the same.
Can somebody help me please? I bought the device 2 weeks ago :(
