I have a basic PC, I've plugged my keyboard into the mic input to record some bits and pieces. I did this a couple of years ago and it worked grand and sounded "real-time"ish, but now when I do it the latency seems to have changed and there's a delay of a second or two between I play the notes and they're sounded in Audacity. The latency was never perfect but it seems to have got worse, I haven't altered the hardware set up in that time so I'm wondering what could make it worse?
