My issue is that everytime when someone goes on-line, off-line, or gives me a pm on yahoo messenger, the audio stops for an instant or goes low volume and after that it returns to the normal volume. I guess this a facility of vaio, don't think is from windows.
How do I get rid of this? For me it's annoying, I want to listen the music without intreruption.
Issue solve, thread can be closed. I'm gonna post the solution in case someone will need it. Is the stupid windows facilites.
Control Panel-Sound-Communications choose option "Do nothing".
