Solved: Major problems with Sigmatel audio card

[LookinAround]

Glad to hear ATI problem is gone!!

And for the script output:
1) you did download the NEW script in my last post (then renamed it .bat extension?)
2) The name of the output file on your desktop is DevMediaData.txt which should be compatible with TechSpot as it's a .txt file

Oh there it is.... I didnt look for it good enough I guess... lol

ALMOST...:evil:

The output file is the correct one BUT your logitech cam stuff should be connected and turned on in order for me to see its driver status/data info so we can finally put all of this issue to rest.


Sooo.... if you are going to throw away, NEVER connect and never turn on and try to use your logitech cam stuff again, we can say we're done now.

However, if there's that chances you may want to try using that webcam again sometime future....etc. etc. etc. Please connect the equipment, turn it on, and then run the batch file again. It will overwrite the old file on your desktop as it creates a new one. If you could post it please.

:grinthumb :grinthumb We did it! Your Sigmatel sound card is fixed! As well as your modem (if you happened to know you also had a modem) !

If you could do one last thing? Update the Thread Title to read SOLVED: Major problems with Sigmatel audio card

Strong evidence the problem was due to the Logitech media class filter!!!
=> We may have found another reason why sooo many people on the Internet can't get their sound cards to work!
=> They should check for media class filters and/or sound device filters!. I'll be adding a post for anyone reading on how to check / fix filter problems with audio devices​

BEFORE: When the Logitech media class filter LVUSBSta.sys existed, every attempt over many months ended with

• SigmaTel High Definition Audio CODEC Device has a problem: 39.
  • Device HDAUDIO\FUNC_01&VEN_8384&DEV_7690&SUBSYS_102801F5&REV_1022
• Modem Device on High Definition Audio Bus Device has a problem: 01.
  • Device HDAUDIO\FUNC_02&VEN_14F1&DEV_2BFA&SUBSYS_14F100C3&REV_0900

AFTER: the Logitech media class filter was removed and the sound card driver re-installed

• SigmaTel High Definition Audio CODEC Driver is running.
  • Device HDAUDIO\FUNC_01&VEN_8384&DEV_7690&SUBSYS_102801F5&REV_1022
• Conexant HDA D110 MDC V.92 Modem #3 Driver is running.
  • Device HDAUDIO\FUNC_02&VEN_14F1&DEV_2BFA&SUBSYS_14F100C3&REV_0900

How to check if filters are being applied to your sound card

Here's an easy method to check if filters are being applied to your sound card

Do the following:

• Start->Run, enter: devmgmt.msc to open Device Manager
• Look under Sound, video, graphics for your sound card
• Rt click your sound card, select Properties, click the Details tab
• Use the pulldown menu to select and check each of the following:
  => Device upper filters
  => Device lower filters
  => Class upper filters
  => Class lower filters

If you don't see anything displayed for any of the four filters above, it means NO filters are being applied to your sound card. If you did see filter(s) displayed:

Device filters are specific to a device. So, if you see a device filter (upper or lower) it was very most likely installed as part of your sound card driver's install and isn't causing the sound card problem

Class filters, however, may have been installed by a different vendor then the sound card's manufacturer (as was the ultimate discovery and problem source in this thread!)
=> Be cautious of non-Microsoft class filters (upper or lower) applied to your sound card
=> "Cautious" simply means it might be causing problems if you're having sound card issues​

To learn more about a specific filter (including the vendor who provided it) install Serviwin
=> If you saw a filter displayed, information about it should appear when you run Serviwin and click View->Drivers
