The error message “There Are No Active Mixer Devices Available” appeared after clicking on the Volume icon in the Windows System Tray. Audio worked fine before shutting the computer down yesterday and clicking on the icon was one of the first actions of the new day.
MP3 playback was still working but games would not launch anymore stating that no audio devices could be found. A check of the sound hardware in the Control Panel was positive. The audio hardware was listed and reported as working properly.
Next step was to check whether the Windows Audio service was up and running. This was done by pressing [Windows R], typing [services.msc] and hitting [Enter]. The Windows Audio service was set to automatic but not started. That was strange but was solved easily by right-clicking the entry and selecting the [Start] entry from the context menu.

The Sound properties were showing the screenshot above stating that no audio device was installed on the computer. The message “There Are No Active Mixer Devices Available” disappeared after starting the Windows Audio service.

Great I had the same problem and my brainy IT guy made be reinstall the OS.
I had this problem at a customer too.
Difference was I could’nt start the service O_o
So I had to reinstall, which sucked.
I’m glad you took the time to post what might have seemed like such a simple or obvious solution — I’ve had this problem before but never knew to check the service. Thanks.
I have been encountering the same problem since some days. Obviously, many users have been getting this problem. Thing is, whats the cause of this problem, and since so many people are getting it… is it because of any virus or spyware? Any answers as to the cause of the problem? I have seen in some forums too about people complaining about this problem.
The cause matters as much as the solution.
This is an answer I have not come across before and I have been ALL over the internet looking for an answer for several months now! However, I did as you said and it was marked as started. I also get the exact same window as you showed above. Another message I get when trying to play one of the Windows waves, is ” Windows cannot play the sound %SystemRoot%WindowsXP Error.Wav. Your sound card may be in use. I would truly appreciate any other suggestions or advice. Thank you ~ Dee

Well, check this:http://www.pchell.com/support/no_active_mixer_devices_available.shtml…It should be helpful for some of you…But many times isn’t, because it may call an “Error 1054″…
Go to Start –> Run, and type in services.msc.
A window will pop up with a list of services. Scroll down to Windows Audio. Right-click
and click on Properties.
Make sure that “Startup type” is set to automatic. Also, make sure, under “Service
status,” start is selected.
Hello, I am having a hard time with my volume too. As with yours, mine says their are no audio devices, but also when I go to turn up my volume, the graphic that shows the volume raising, shows the volume staying at mute. I cannot access volume control because it ways that their are no mixer devices available. So
I go to download some mixer devices by going to Add Hardware and it ends up saying that it cannot find the software necessary.Also, when
I try to go on Windows Movie maker it says that the required audio drivers are not available, I don’t know if this has any connection but it would sure be a wonderful deed if someone where to help me with this.
Please, Please help, I have been suffering with this for 6 months now and my family doesn’t have the money to get a new computer. Anyone who can help me is a kind, kind angel. Seriously..

I use only win doc updates, for Windows, but automatic updates is off
yeah, and we all know how much Windows company lose founds of the pirate copies :)
