        I don't know if you noticed such a situation. When using the audio or video playback software such as Thousands of Listening, Storm, and other audio games under Windows 7 system, the audiodg.exe process will cause the CPU usage to soar to over 80%.

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

Although I don't know the root cause of this situation, I found a simple solution after asking some Windows 7 users.
