Why hasn't Dell gotten new audio drivers from IDT (the new owners of SigmaTel) and posted them on the Dell download site?  IDT requires that new drivers are only available through the retailer.  How long do we have to wait before the microphone and speakers will behave properly in Windows 7?  Is it too much to ask that a computer that is 6 month old can be updated to the latest operating system with workable drivers?
