After installing Linux Deepin on wubi, Windows 7 has no sound problem

        Question: Just wubi installed deepin linux 12.12 official version, switch to windows 7 found that the speaker has no sound, and then check the speaker is no problem, the built-in speaker is no problem, the motherboard audio interface is no problem, well, met strange things . . . Helpless, help google:wubi install windows headset no sound The first two are the answer: Close your notebook for about 5 seconds, then re-enter windows 7, so that your notebook can sound through the audio interface on the motherboard! Note: Do not reboot, but shut down! The former is a hot start and the latter is a cold start. What is the difference between the two, why does Windows7 have no sound, and I don’t understand it, just like the deepin official reply: how is it possible! Both are two different systems! However, I guess that when the hot start, the two systems share some registration parameters, and just Linux has modified some registration parameters, Windows does not recognize it, and the cold start these registration parameters will be lost after shutdown, so Windows 7 re-initializes these The parameters are normal. I have to say that this problem is the most amazing fault I have encountered in computer games for so many years. It is very simple to solve, but I have no way to check it out. I have ruled out various hardware anomalies, and also removed wubi deepin, reinstalled drivers, After rebooting the system, the system is reinstalled. . . result. . . Liu dark flower Mingyou Village~
