So I'm trying to get my laptop's onboard speakers to work again. They were working fine one day, then after a reboot, they simply disappeared. This problem has been ongoing for about a month.

This is on Windows 7 x64 Professional. The laptop is a MSI GX620.

  • The sound does not play from either the speakers or the headphone jack.
  • The onboard mic does not work, either.
  • There absolutely nothing regarding either my speakers or mic in the device manager under the Sound category.
  • Doing a "Scan for hardware changes" brings up nothing.
  • No devices are listed under "Playback devices" or "Recording devices" in my computer's sound properties.
  • I have tried to install every audio driver known to mankind with no luck.
  • There are no BIOS settings regarding audio or onboard audio at all.
  • I have booted to a Linux Mint LiveCD, and the sound properties are also missing the audio.
  • HDMI audio and USB sound cards do work, but are inconvenient.
  • The warranty is expired, and even if it wasn't, it would be voided since I have a new HDD installed (months ago; unrelated to the current problem).

As far as my motherboard is concerned, I somehow completely removed all traces of any integrated sound from it.

I've done everything I could think of. Anyone have any ideas?

Even though I've tried a LiveCD with no luck, is it possible that a full reformat of Windows could fix the issue?

It sounds to me like your sound card just quit on you. If neither Windows nor a LiveCD can detect anything, it probably isn't there. – ephilip Sep 6 '11 at 0:22
    
Clear the cmos on the motherboard, then enter the bios and set the date and time before windows loads, see if this does anything. – Moab Sep 6 '11 at 2:23
    
what commands did you try on the livecd? does it turn up on lspci or lshw? – Journeyman Geek Sep 6 '11 at 2:58
