Help with High Def Audio Driver and Win 8

Anonymous

I installed Windows 8 - wiped out the programs and kept the personal info.  Now I dont have any sound. 

Checked the device drivers and the High Definition Audio Driver isnt working or was not installed.  I deleted the one that was there and rebooted.  Still wont work!  I cant seem to find a driver that will work. I tried updating the driver and it could find any on the pc or internet.  It was working under Vista and Win 7..

Any help would be greatly appreciated!  Thanks, Dave

    Hi ELOHMcDonald,

    Can you check the following registry key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E96C-E325-11CE-BFC1-08002BE10318}

    At that registry key, in the right window, is there, under "Name", either an UpperFilters or LowerFilters value?

    If so, for each of the UpperFilters and/or LowerFilters value, what is listed under "Data"?

    The issue is likely the LVUSBSta LowerFilters value.

    The LVUSBSta.sys is a component of a Logitech camera driver.

    Try removing the LVUSBSta value.

    To remove the LVUSBSta entry double-click LowerFilters and, under Value data, remove LVUSBSta > OK

    Create a system restore point beforehand and restart the computer after.

    Alternatively you could try updating the Logitech camera driver to a more recent version if possible.

    Congratulations; Repair by intimidation.

    After I responded this morning, I turned the PC off. When I got back this afternoon and powered up and was fixing a cool drink, I heard this strange noise--Windows start up sound.

    I'm not really sure I did anything.

    The Audio card driver shows good and I hear sound. I've tried a few programs, etc.

    The HDA driver still has the yellow "!"

    I don't argue with success and I am making a back up after I press SEND.

    I've, nonetheless, kept your suggestion about the Logitec file and will continue with this if the audio stops again.

    *****

    What I excluded earlier - so that it would not complicate (?) the issue - was that other drivers had been dying off for the last few months.  1st the CD, then the PS2 ports, when it finally hit the HID, I could not get into it at all.  I remoted, found the error, and copied the drivers off a back up about 3 wks ago.  I got my stuff back.  The audio was still working but quit some where in there with all the 'experiments.'

    Everything works now.  I suspect aliens.   No malware or virus on scans.

    Thanks for your help, Auggy.
