I just experienced this annoying scenario and I hope other users can try out and see if you can replicate it.
While listening to music.. all is well. Until you get and incoming call. Once you're done with your chat, the music which continues will be in mono!
I've tried both powerAmp and Walkman apps. The only wait to regain stereo is to re-plug in your earphones.
Please confirm this scenario and i will post it up to the Sony forums. Thanks!
