Hi i am currently running a XPS 720 with Windows 7. I have had Windows 7 on the machine for years and only recently have experienced sound problems. Audio Does not play, or play a test tone. Audio also doesnt work with my USB Gigaware Headset(basicaly its own external soundcard).
I have tried the following steps.
-Downloaded and Installed the newest Audio driver 'SIGMATEL STAC 92XX C-Major HD Audio Driver Version A03'. -Purchased a new external sound card thinking that may be the problem. I disable the onboard soundcard prior to installing the new drivers. After installing it, i troubleshooted it in every which way, to get it to work and play a test tone or sound. Many long calls with Diamond customer service (the new cards manufacturer) but no luck. -Removed PCI soundcard and re enabled onboard audio. -Removed the video driver and reinstalling the current one without the audio. -tried restarting the windows audio service in services.msc -Uninstalled a Windows Update that was said to cause the sound problem (link below) http://answers.microsoft.com/en-us/windows/forum/windows_7-pictures/windows-7-failed-to-pla y-test-tone/850853d2-eea0-4f53-972d-14515f80554d

I am stumped, been researching and trying things for 3 weeks now to alleviate this problem. I was wondering if I am missing something here?Any suggestions? Thanks in advance.
