I don't know if you noticed such a situation. When using the audio or video playback software such as TTP, Storm, and other software under Windows 7, the audiodg.exe process causes the CPU usage to rise to the moment.

After that, the audio share of audiodg.exe can be maintained between 6% and 8% after the playback software enters the playback state. After

Ordinarily, CPU occupancy rate of increase is not uncommon transient, but the application form into the general body of work, 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.
