Xperia S loud speaker problem

[#1]

I bought S around 10 days ago and today i started having problem in its loud speker.

Lots of jerk in the audio from loudspeaker,  ringtone, audio / video played  through loudspeaker have these jerks. Audio is barely audible. All you here is glitches and jerks

Not sure if it is hardware of software issue, but 1st time i restarted my phone problem got solved. After few hours the same issue repeated and not solving even after 3 restarts.

Kindly suggest.

Best Regards,

Rahul

I have the same problem on my Xperia S and it come with an error aswell saying that the device's microphone and buttons are not available.

I tried reinstalling the software, reparing via PC Companion but nothing...it is a problem ith the mother board and we cant touch it.

Did any of you solved this problem?
