After wubi installed Linux Deepin, there was no sound in windows 7: After wubi installed the deepin linux 12.12 official version, I switched to windows 7 and found that there was no sound in the speaker, then I checked the speaker and found that there was no problem with the built-in speaker and the audio interface on the motherboard. Well, there was a strange problem... Google: wubi install windows headset no sound the first two are the answer: Close your notebook for about 5 seconds, and then re-enter windows 7, in this way, your notebook can be voiced through the audio interface on the motherboard! Note: Do not restart, but shut down! The former is hot start, and the latter is cold start. What is the difference between the two? Why does Windows 7 have no sound? I didn't understand it, just like the official deepin reply: how is it possible! The two are two different systems! However, I guess the two systems shared some registration parameters during hot start, but some registration parameters were modified in linux, and windows could not recognize them, after shutdown, these registration parameters will be lost, so that windows 7 can reinitialize these parameters normally. I have to say that this problem is one of the most amazing failures I have encountered on my computer over the years. It is easy to solve, but I have no way to troubleshoot it. I have ruled out various hardware exceptions, wubi deepin is also deleted, the driver is reinstalled, and the system is restarted... Result... Liu Yinghua mingyoucun ~ Conclusion: (1) this is actually not a problem: You just need to take a nap after shutting down, haha ~ (2) Many people only know the difference between restart and logout. It is estimated that few people know the difference between restart and shutdown-boot. Finally, this bug should occur under the specific kernel/driver, because it has not been encountered for so long. Well, we will not try this kind of thing in the future. There are too many bugs and there is little value to use...
