Recently, the volume has been fairly low. System volume is at maximum. Winamp volume is at maximum. Speaker volume is at maximum. Still not particularly loud. I know the volume is lower when going via the speakers, so I started thinking I should bring in an extension lead and plug the headphones directly into the computer.
Only problem is that would mean no speaker volume control. What to do? "Perhaps I could use the volume control on the headphones themselves... Let me just test it." Ah, I see now - it's on low... My music has returned to normal volume now. :-)
