For some reason, about a couple hours ago today the audio from my Headphones (sony ch710n, connected by wire to logitech USB adapter) has been slightly degraded. I encountered this problem a couple months ago as well, which was solved when I reinstalled Windows. Is there any other way to fix it? The best way I can describe the sound quality is that it sounds "flatter", and I can't hear some elements of the music I'm listening to.
