No Mixer Devices Available

[vivalive]

After i login to windows,within 10minutes,i will be lagging for a few seconds,
after that when clicked volume control,it says that there is no mixer devices available.

but before the lagging,i am able to listen to songs and using volume control.
is it hardward or software problems?

thanks for advice.

Check your device manager for audio drivers.

And let us know if it shows any.
