Could it be that while recording from firefox you had the soundcard (auto)connected to the same track as well ? That would add the offset if the cause is your soundcard (which I suspect), even if the headset is not plugged in. > So if you ask me exactly how much DC offset I dont know how to find out in > figures. The audacity track shows it 1/4th to 1/3rd way up. Center is 0.0 > top is 1.0 inbetween is 0.5. > This is little more than half way between 0 and 0.5. Which is way too much, and indicates broken hardware. So please check your connections and then we'll see again.
