Vista - the audio service is not running

Ok so this just appeared on my mams Compaq Presario c500 laptop. I've
spent hour researching and trying to fix this problem, but I keep
coming across people with a similar problem. I'll explain mine first.

My speaker icon in the taskbar has a red cross on it. When I hover my
mouse over it, it says "The audio service is not running", if I right
click it I get 3 options
1. Playback devices
2. Recording devices
3. Sounds

There is also an open volume mixer option but it's greyed out.

When I click on ay of them I get this message

This computer cannot play audio because the windows audio service is
not enabled.
Would you like to enable the windows audio service?

When I click yes it takes me to the sound options and it says all is
working, yet I still have no sound.

So I kept looking for answers on the net and found to look in
services.msc and windows audio.

That's where I differ from everything else I see on the net, as I
don't have a windows audio service in there nor do I have a "windows
audio end point builder".

However I do have these 2 options

audioendpointbuilder
audiosrv

Both of which give 2 errors when I double click them
1. Configuration manager: a general internal error occurred
2. The system cannot find the file specified


If I try to start audioendpointbuilder I get this error message
"Windows could not start the audioendpointbuilder service on local
computer
Error 193: 0xc1"


If I try to start audiosrv I get this error message
"Windows could not start audiosrv service on local computer
Error 1068: the dependency service of this group failed to start."

Now I can't seem to get any further than that.
I have tried reinstalling the driver and making sure the audiosrv.dll
is in system32 folder.

Im running vista home premium 32bit and my sound is a conexant high
definition audio card


Any help really appreciated

Thanks in advance

When you say you've tried re-installing the drivers, are you using those that came supplied with the laptop, or have you visited the Compaq website to download the newer Vista certified driver?

I took the liberty of locating them for you: Software & Driver downloads*Compaq Presario C500 CTO Notebook PC#

well origionally i had tried the drivers that came with the laptop but

thanks so far

When I search the HP/Compaq site for Presario c500, I got a lot of results, mostly variations of Presario c500 that I'm guessing are various model numbers.

Compaq Presario C500 Notebook PC series
Compaq Presario C500 CTO Notebook PC
Compaq Presario C500EA Notebook PC
Compaq Presario C500EU Notebook PC


Perhaps you should check too, just to make sure that the link I supplied earlier was infact for your particular model? This will take you to the search results: Product search results

Make sure, too, that in Services, the Multimedia Class Scheduler is set to
Automatic.

I don't think you have a driver problem, but have, possibly, a Windows
system files problem. For example, is audiosrv.dll found in
C:\Windows\System32\?

Run the System File Checker. To do this, right-click on the Command
Prompt shortcut (in Start Menu\Programs\Accessories), and choose
Run as Administrator. Copy the following, and Paste it after the prompt:

sfc /scannow

Press Enter. It will scan all your system files. It may take a few
minutes. If things are okay, you are given the text message "Windows
Resource Protection did not find any integrity violations". If things
aren't okay, it will attempt to replace the bad system files.

ok so ive checked multimedia class scheduler and that is set to

audiosrv.dll is present and correct.
but as for the checking of system files i tried this and it came back
with an error and created a log file for that, so i weent to the log
file but it told me i didnt have permission to view it.

any ideas.

To open the entire cbs.log, try right-clicking on Notepad, and then choose
Run as Administrator. Then use File > Open to navigate to the log. Since
the log may be huge (it's used by other programs besides the SFC), you might
want to do this:

To create relevant SFC-only information gleaned from the cbs.log, and put it
in a small file called sfcdetails.txt, right-click Command Prompt (using the
shortcut in Start Menu\Programs\Accessories) and choose Run as
Administrator. By default, the prompt starts
in C:\Users\(Your Name). Type:

cd desktop

Press Enter on your keyboard. Then Copy and Paste this at the prompt:

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt

Press Enter. Sfcdetails.txt should then appear on your Desktop.

Looking at entries for the latest date in that
text file , what files are noted as being problematic?

its the only bit of the log i can see that has anything to do with
sound.

so i tried to replace the audiosrv.dll with another one but it says i
dont have permission to do anything with system32 folder.
