Complex programs, such as audacity, are not the right tools to troubleshoot hardware and driver problems (in my opinion).

I would begin by turning down "Digtal" (that control is very touchy for my Intel ICH8 card). -- Regards, | http://users.icfo.es/Florian.Kulzer Florian | -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
