Really? I'm having the same problem too... noisy static noise during phonecall (not that loud, but noticeable - and it occurs only at my end)
I own several phones before and commonly place calls at my usual location (medium to strong reception) and never encountered any issues with my previous phones (motorola and htc).
The thing is.. I can send it back to check (and I have a 2 years warranty) - but maybe I'll check with one of my friend who own an xplay to compare if the static noise is there still...
Checking on Google I found several other Xperia model that also have similar issue (Xperia Mini with it's videocamera recording static noise) - and also in phone arena where they mention of the xplay static noise as well (http://www.phonearena.com/reviews/So..._id2838/page/3
It's really frustrating...
Anyway thanks for the info.
Ok I've tried using earphone and I made a call. Everything was crystal clear. On the same call I disconnected the earphones and checked the earpiece, static noise and crackling noise was there. It is highly a hardware issue. Tested both on GSM and Skype.
Sent the phone back for warranty, and got it back within 3 days. Earpiece issue was fixed. Sony SC even upgraded my ROM to 2.3.4 (videocamera with autofocus now!) and threw me a nice 2012 Xperia calendar
If it's not broken, don't FIX it!
