Dell XPS sigmatel 975 C-Major Audio doesn't work

  • HI:
    I have  a 3 month old XPS the the microphone refuses to pick any sound.  The sound recording check box is checked for the microphone but nothing is recorded. 
    I have updated to driver 3/11/2005 as well as the BIOS to A04.
    Any ideas?
  • We had problems like that with ours. After futzing with the control panel mixer, in both playback and record panels, as well as rebooting, we finally got it to work. One of the times that this happened, we were able to correct it by going to Device Manager and disabling the audio device. Then re-enabling a few seconds later. I don't think this audio chipset is without problems.
