Win resolved under 7 audiodg CPU high occupancy issues

I do not know if you noticed such a case, when TTPlayer, Storm video and other audio or video playback software category used in Windows 7 system is running, audiodg. The exe process causes the CPU usage to rise to over 80% instantaneously (as shown in Figure 1, the highest value I have ever detected is 90%). After that, the audio share of audiodg.exe can be maintained between 6% and 8% after the playback software enters the playback state.

Under normal circumstances, CPU usage is instantaneously high, but it is not uncommon, but when the application enters the normal working body, the system The CPU share of the process is still between 6% and 8%, which seems to be difficult for users to accept. Although I don't know the root cause of this situation, I found a simple solution after asking some Windows 7 users.

Right click on the speaker icon in the system tray and select "Play Device":

Then, a dialog box will pop up, please double click on the playback device you are currently using. (Figure 2).
