There are no active mixer devices available

What I have done;

Check the Device manage - no errors
Uninstalled the Realtek sound chip and installed the lastest drivers for this.

Have Check the BIOS - sound is enabled

The windows audio service is enabled to automatic within services.msc.

Even when I install a separate sound card I still have this problem.

This problem has occured twice now - when I have recoverd the computer.
Oldish computer with recovery with service pacl 1(XP) - the sound is fine
then and no problems, the sound suddenly stops when the full version of
service pack 2 is installed from the microsoft update.

Obviously need SP2.

Any clues out there?

See similar post from Buminator below this one.
I believe this is onboard sound so go to the mfr. of the m/b and get the
correct drivers.

Ta for the reply.

Hve already done this. Also have updated the BIOS.

I really don't think this is a driver issue anyway. (all updated)

The problem happens when service pack 2 is installed.

It seems to be the WINDOWS AUDIO service (which usually controls the ACTIVE
MIXER) is not starting correctly.

RECAP
With SP1 te sound works fine
SP2 no active mixer.
ALL drivers updated
Direct X updated
BIOS updated and chipset.
Audio enabled in BIOS - Also have disabled and tried another sound card -
Performed ATX reset with each.
Windows AUDIO SERVICE set to automatic - have tried the manual approach as
well.

It has got to be something to with SP2 - maybe a windows registry issue ????

Thanks for the reply

HI All,

I have a Dell Latitude C640 with a similiar problem. Before I
installed SP2 on my XP Pro, the sound worked fine.

Afterwards, I get nothing except beeps from error codes.

I tried going into Device Manager, but everything just says
"device enabled, but not started".

I tried going into "services" section of adminstration properties in
Control Panel, and have set "Windows Audio"
to start automatically. I even set the recovery status to
restart when an error occurs.

ALL to no avail - still NO sound!

The original configuartion on this machine was an onboard sound chip
from Intel - I tried to restore to this point already once. The chip
was identified as an: Intel 82801CA/CAM AC'97 Audio Controller in
system information. However, when I did a search for drivers, on the
Intel site, I could find NONE. They had drivers for the following
chips: 82801AA, 82801BA and others, but NONE for the CA.

Then I went up to Dell's support site for the laptop. They suggested
an upgrade to a Crystal SoundFusion sound driver - which I did download
and install. When I go to Device Manager it does detect it, but it
gives me the same message - driver is enabled, but not started.

If I click on the icon for the "Sound Volume" in Programs>
Accessories>Entertainment it says, "No Mixer Device detected" - go to
Control Panel and "Add Hardware". When I try that, it says everything
is there, and all drivers are installed.

I really think this is a WinXP SP2 issue, but I have NO idea how to
resolve it.

Any ideas or suggestions would be greatly appreciated.
Thanks in advance!

Jim

The solution is claimed to be in the post by "wild-child" near the end
of the thread. The last poster in the thread claims it works.

http://www.dellcommunity.com/support...cending&page=1

The Dell Resource CD has the Crystal Semi driver in question. So
R48991 shipped with the laptop. The Dell site refers to the chip
as CS4205, and yet the driver package INF makes reference to
CS429x. (Far be it for me to argue with Dell...) It could be that
CS4205 is two channel, and is a subset of the CS429x family.

You can get R48991 from here. The downloaded file is "C5mua09i.exe" and is
1,695,432 bytes. When you double click on C5mua09i.exe, it dumps the setup
files in C:\dell\drivers\R48991 . I really like that feature of the
couple of Dell drivers I've played with, as it allows exploring how
things are bolted together.

http://support.us.dell.com/support/d...0&fileid=57707

Wild-child suggests clicking on "CrySetup.exe" in the R48991 folder.

1) Click on "CrySetup.exe"
2) Select the "Remove" option. That will clean up whatever
mess already exists, at least in terms of removing whatever
Crystal thing got installed already.
3) Wild-child suggests repeating step 2, instead of restarting
at that point, but I wouldn't bother. The Remove should do the
right thing in one pass.
4) Restart.
5) In Device Manager, the Crystal Audio should now be
driverless. Offer to update the driver, and point to the
R48991 folder. Apparently, you're supposed to use "cwawdm.inf".
6) If step 5 worked, you're done with Device Manager.
7) The next step involves toggling the volume icon setting,
first unchecking it, then checking it, as a means of forcing
the appropriate stuff into startup and registry. To quote:

"go back to sound in control panel, double click on "sound and
audio devices" here "uncheck" the option (Place volume icon in
the taskbar) click on Apply now go back and "check" (Place
volume icon in the taskbar). thats it."

The result of that should be to leave a volume icon in the Taskbar.

Give that a try. Sounds like fun :-)

On my computer, as long as the AC'97 sound is enabled in the BIOS,
I can then see it in the Device Manager. Start by checking the BIOS
setting for AC'97.

There are no active mixer devices available. To install mixer devices, Go to Control Panel and Other Hardware, and then click ADD HARDWARE

I sometimes get this error and it solves after restarting...
also i started when i accessed service.msc...
please tell me whether it's due to a virus or drver problem.

P.s.: I got hp laptop and i updated the drivers with hp s/w update.

reinstall your sound device drivers.

This is not a hardware issue, it's a software issue, todays pc sound is all
controlled by software, your mixer device is configured by software. please
list your audio device, ie is it a realtek driver or what?
