There are no active mixer Devices

After the system is re-transferred, the audio cannot be decoded no matter what player I use to play the video. At this time, click the volume icon and report the error "there are no active mixer devices available. to install mixer device, to go control panel, click printer and other hardwares, and click Add hardwares. ", but under the printer and other hardwares option of my control panel, there is only the Add a printer option. At that time, I felt the driver problem, so I re-switched the audio card driver, the result is not long before the problem occurs again. I have reinstalled the system, but the problem persists.

Solution:

Start-> Run, enter services. MSC enters the service and starts the Windows Audio Service. this service is used to "manages audio devices for Windows-based programs. if this service is stopped, audio devices and effects will not function properly. if this service is disabled, any services that explicitly depend on it will fail to start."
