How to fix this error: No audio device - no active mixer devices available

Dell Latitude D520 notebook - Windows XP Home - only about 6 months old. All of a sudden, sound doesn't work. Well, system sounds come through but there is no volume control in the task bar. Control Panel - Sounds : everything is greyed out and it says "No audio device". Device manager does not show any errors; under Sounds, it lists several items and says they are all working properly. Tried the Windows troubleshooter for sound, but when I click on the link for Volume Control, it says "there are no active mixer devices available". Read all the posts here on that subject with no help. Downloaded the SigmaTel driver from Dell (the only sound driver listed when I searched based on service tag). Installed the driver with no errors. Rebooted. Still no sound. System is free of viruses, adware, spyware, etc. This problem just cropped up and I have no idea why.

Are there any yellow-coloured ! or ? in Device Manager - specifically under "Sound, video and game controllers"? (Start, run, type devmgmt.msc <hit enter>)
0
 
and235100Commented:
If so - then you will need to update the device driver(s).

Also - see if any of the devices have been disabled (red x) - if so - re-enable them.

19641244: As I mentioned in original post: no errors in Device Manager; no yellow question marks. Device Manager reports that everything is running ok. Also, as mentioned in original post: I downloaded the only driver available from the Dell web site and installed it and it did not fix the problem.

Additional info:
When I run iTunes, it says "iTunes has detected a problem with your audio configuration".

When I run Windows Media Player, it says "Windows Media Player" cannot play the file because there is a problem with your sound device."

Okay - can you please list what is detected under "Sound, video and game controllers"?

That rules out devices being disabled from the bios.

Have you tried uninstalling all these entries from Device Manager - then rebooting?

Also - check out http://support.microsoft.com/kb/315539 - and remove all greyed-out entries - then reboot.

Could you also check that Windows Audio is started and set to Automatic in services.msc?
0
 
alicia1234Author Commented:
will try that and report back -
meanwhile I did notice that in device manager under "System devices" there is a yellow question mark on "Plug and Play Software Device Enumerator".

alicia1234Author Commented:
I already checked Windows Audio - it is started and it is set to Automatic. I even tried stopping it and restarting it.

and235100Commented:
Okay - this is probably something to do with it - on no account uninstall that item for the time being - until you have tried my other suggestions.

>>> Have you tried uninstalling all these entries from Device Manager - then rebooting?

I'm confused about how to uninstall them from Device Manager. For example, if I right click on "Audio Codecs" my only options are Update Driver, Scan for hardware changes, and Properties. If I click Properties, then the Properties tab, I get a long list of things, and there is a "remove" button. Are these what I'm supposed to be removing?

I do not have any of the Windows XP system CD's with me - will this be a problem?

If above is still not help, do system restore see if it helps.

I'm not comfortable doing a system restore as it is not my pc (it's my sister-in-law's) and I don't want to totally wreck it! ;-(

and235100Commented:
"I do not have any of the Windows XP system CD's with me - will this be a problem?"

Shouldn't be... - as the base drivers are kept in the Windows folder - even if you uninstall them.

I should have been more specific
Ignore the Remove button under the Audio codecs/video codecs Properties tab.
Of the following:

Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
SigmaTel High Definition Audio CODEC
Video Codecs

Only "SigmaTel High Definition Audio CODEC" should be able to be uninstalled.

But the issue with the PnP Software Device Enumerator does seem to be highly likely to have affected the sound on this install.

and235100: How do I uninstall the sound items from Device Manager (see previous post above)
0
 
and235100Commented:
The reason I suggested unhiding and removing all the unattached devices was that there may be a conflicting driver.

PUNKYCommented:
System restore will not damage or wreck the system. Start > Programs > Accessories > System Tools > System Restore

It will restore system state back to sometime you know the sound worked. It would however remove any programs or update but data is safe.

and235100Commented:
System Restore will only restore the software state  - it will not necessarily remove the problem with the PnP Software Device Enumerator...

alicia1234Author Commented:
and235100- sorry just noticed your post about sigmatel being the only driver that could be uninstalled. You're right on that one. Should I go ahead and uninstall it? Or should I pursue the pnp stuff?

and235100Commented:
"How do I uninstall the sound items from Device Manager (see previous post above)"
The general rule of thumb is to r-click the device, and select Uninstall - but as I said - this will not be available to the standard windows codecs and MCD's...

0
 
and235100Commented:
I think that the problem with the PnP device enumerator is causing the problem - it might be better to resolve that first - because unless I am mistaken, in the list you posted - there is no actual "audio" device - just the supporting codecs...

OK, it's fixed!
From the link you gave (http://www.annoyances.org/exec/forum/winxp/t1066427444)
 I determined I needed to find machine.inf, which I did and I deleted the line they said to delete.
Then I uninstalled the pnp enumerator from device manager.
Then I did add new hardware > next > yes I have already connected the hardware > add new hardware device > install the hardware that I manually select from list > system devices > have disk ...
browsed to c:\windows\inf\machine.inf ... clicked "open" ...
Then selected "Plug and Play Device Enumerator" from the list
It installed.
I rebooted.
Sound is now working.
Thank you so much!!!
