I am having a problem when I record muliple tracks. The first track is always perfect, no noise, no buzz, no problems. Whenever I add subsequent tracks everything is fine for the first 25 to 30 seconds then I start to hear noise on playback. I reloaded Audacity 1.2.6 and the ammount of noise is less, but not acceptable. This happens using microphones, guitars, whatever. I am using a dell Inspiron 1501 which does not seem to be the best laptop in general, but when I first got it running under Vista I could make decent multi track recordings. The problem was Vista was so unstable that I went to LINUX (will not run on a dell Inspiron 1501, thanks Bill and the folks at MS) so I had it reloaded with XP. Now I can`t get multitrack Audacity recordings as mentioned above. Could it be the sound card? Does anyone have any idea why this should be happening? Thanks for any help.
