For a while I have been dealing without sound but really want it fixed. I started trying
to install the Realtek AC97 Audio Controller and got the Code 39. Now in Device Manager
there are the following all with yellow dots with an exclamation point:
MS Kernel Acoustic Echo Canceller
DRM Audio Descrambler
GS Wavetable Synthesizer
System Audio Device
Wave Audio Mixer
MS Streaming Clock Proxy
Quality Manager Proxy
MS WINMM WDM Audio Compatibility Driver
Realtek AC97 Audio
I felt like the tour manager for The Rolling Stones.
I have tried several different things starting with uninstalling all of them and re-installing
only the AC97 I had a friend download the AC97 driver from his computer. Still with the
end result. Error 39, no sound. One thing that did rid me of the code 39 was doing a registry
edit (and I'm going to sound like the novice I am) on some information like end value or something
that was somewhere I'm sure I wasn't supposed to be so I touched nothing else and was
rewarded with an error code 10. The next day, a friend who is knowledgeable(I thought) tried
something and the error 39 was back.
Today I found out that Kernel System Audio Device and the WINMM WDM Driver are supposed to
be on the computer. In checking, both the drivers
sysaudio.sys and wdmaudio.sys respectively
are in the C:WINDOWS\system32\driver folder and there are (2) sysaudio and (1) wdmaudio
in the Driver Cache. When looking at the properties in device manager it shows those drivers in the
details and when you try and update them it says it cannot find a better driver. But, when I
try to tell it which driver to use it says "This item has no information...". Oi...
I do feel stupid on this one, though. At one point, I had come across a file that was similar to the
services file that shows if an item is started, if it is a manual or automatic start, etc., but it showed
all of the drivers, the kernels, all kinds of things. I inadvertently closed it out and haven't been able to
find it again. But it showed that these 2 particular drivers were installed and "OK" but were just
turned "Off". Could that be the whole root to my problem? Probably not but it was a nice fantasy.
If anyone has any thoughts as to what to do I would greatly appreciate it. Hope you can decipher
all this. Thanks in advance.
