plug and play software enumerator

[biohazard]

Ok so heres the problem i've recentley reformated my system for my usual 6 month cleanup of it. I did everything like i have before. After reformating i reinstalled all the drivers for the system, and then proceeded with the windows updates. I went through the first 3 rounds of windows update without a problem. When i doanloaded SP2 though i lost all sound and saw in my device manager i had a yellow ? mark on plug and play software enumerator. After hours trying to figure out what to do and reading many forums I couldnt fix it. I decided to reformat again whick i just finished up right now. At first it fixed the problem until i installed SP2 again. So im guessing it has to SP2. Does anyone know how to fix this? (sorry for the long post)

well i guess no one knows

I wouldn't worry to much about the sound driver as it should be able to be installed at any point (after or before sp2). But I would install the sound device through the Device Manager. Right click on the device and choose update driver, then browse to your driver. Give this a try for reinstalling the software enumerator...

1. Copy machine.inf from %windir%\inf to a temp dir.

2. Remove line 20: ExcludeFromSelect=*

3. Add new hardware have disk (select the temp dir with the modified machine.inf) and install the plug and play software enumerator.

Hope that helps.

Thanks for the reply. I tried what you sugested but it still doesnt work. I tried just updating and then totally removing it and reinstalling it then updating and still nothing.

thanks for the reply. Well i tried updating the drivers using the machine.inf and unistalling the plug and play snumerator and reinstalling it using the machine.inf file. Neither seem to work i still have a yellow exclamation mark on the pnp software device enumerator in the device manager. I tried uninstalling and reinstalling my audio drivers too. nothing works. Theres gotta be something different.

Found this on another forum

Hey guys,

I've had problems with my sound the last couple days too. I would install my sound drivers and they'd be running without conflict in my device manager but when I opened my sound options in control panel it showed 'no device'. I went to numerous forums where they all told me to uninstall my drivers and install them again, or to enable sounds in windows or to install non-WDM drivers but nothing worked! UNTIL today. I came across a post(sorry, can't remember where...) that told me to make sure that my 'plug and play software device enumerator' was installed. AND IT wasn't! Installing it was kinda complicated and involved copy and pasting this:

md \temp

cd \temp

copy %windir%\inf\machine.inf \temp\allmachine.inf

copy %windir%\system32\drivers\swenum.sys \temp

copy %windir%\system32\streamci.dll \temp notepad \temp\allmachine.inf

into cmd line and then opening the allmachine.inf with notepad and erasing what was on line 20(or so..)

under the line [ControlFlags]then adding new hardware through the control panel

select pick a list

and click on have a disk

and choose the allmachine.inf file that is in the c:\temp folder

it will give you a new list of devices you can choose and the 'plug and play software device enumerator'

install it

and then reinstall your soundcard drivers!

done.

*please note* These are very general instuctions. They were laid out much clearer on another post. I wish I had the link for you but with this information I'm sure you'll find it if you look.

Thanks for the reply. I tried what you stated in the post but that also did not work. I think it might be a conflict between drivers though. When i go to saound and audio devices it says no device but when i then go to check on my audio device in the advanced section its there. When i clcik on it it says it is enabled but not started. I went to services but i did not see anything related to the drivers.

This message goes out to all of you who hadn't the luck to get their sound back to

life with the given solutions in this thread:

I followed all steps, but still my "PnP software enumerator" (or in german "PnP Softwaregeräte

Enumerator") told me that he couldn't load the needed drivers. Consequently I had

still no sound. I also made a windows repair install, but the problem was still there.

After hundreds of trial & errors I finally came to a solution for WIN XP!:

1.) Deinstall your sound drivers. Save streamci.dll and swenum.sys and machine.inf

to a temp folder as mentioned above.

2.) Deinstall your failing "PnP software enumerator".

3.) Go into the registry via regedit or the editor of your choice. In there close

all keys so you just see "my work", "workplace" or whatever the englisch name for

the german "Arbeitsplatz" is (it has a little computer symbol next to its name, I

guess you know what I mean.)

4.) Then search for "swenum". Delete every key that you find. Before you do so I

highly recommend to create a system restore point or a backup of your registry, just

in case something goes wrong. You have to delete the whole key, not just the line

with "swenum" in it. For example: You'll find the word "swenum" in a key where you

can also find "pnp software enumerator" and some other entries. Again :You have to

delete the whole key. On the left side you see an open folder in which you are in

right now, deleteing this folder means to delete the whole key. Do so, it the quickest

and easiest way. If there comes a warning that you don't have the permission to do

so, right click the folder and give yourself the permissions to delete the folder

;-)

Do this for all keys where you find the "swenum" in it. You should find about 5-10

keys.

5.) After you finished close the editor and reopen it again. Research the registry

to make sure their is no more swenum entry.

6.) Restart, then check your registry again. Just for the case Win XP has reinstalled

something. If you find another "swenum" entry delete it. Do also search for "PnP

software enumerator". If you have done right before you shouldn't find anything.

If you do anyway, delete the whole key again.

7.) Go to "windows/system32/drivers" and delete swenum.sys.

Also go to "windows/system32" and delete the file streamci.dll (don't do that if

you have forgotton to follow step1 of my description!)

8.) Now reinstall your "PnP software enumerator" following the steps mentioned in

the posts above. (In the hardware manager click "have disk" and choose your temp

folder and the inf file in there, choose "PnP software enumerator" under standard

devices or something like that).

9.) If you have done right you should have the "PnP software enumerator" back without

showing any errors. If you have done right Win XP shouldn't ask you to restart. Now

install your sound drivers, restart and be happy again.

I hope this solution did the trick for those who didn't find the posts above solving

their problems. Maybe some steps can be left out, but I recommend to follow all of

them, because I'm not sure where the errors is hiding exactly.

I read that from another forum and decided to give it a try. To my disbelief it actually worked. So im guessing if your plug and play software device enumerator is in your device manager but has a yellow exclamation mark on it use this metiod. And if its not there at all use the alternate machine.inf install method. (just thought i'd let you know for future reference. )
