Hi,
I had same problem and fixed it.
Problem:
No sound coming out of speakers using any application such as GOM or WMP.
Diagnosis tools says that audio realtek is working.
Solution:
Download audio driver update from Sony Vaio to fix SP1 sound problem. As
long as you're there (at Sony) check out any other updates.
