[Learn with Hao] Mysterious phenomenon (question post)

Today, Hao haocodeCodeCode is very hard, just escape from the Ubuntu on the mechanical hard disk, return to the SSD win7 preparation for entertainment.

Well, I decided to kill him. Why don't I hear a headset when I turn on Three Kingdoms? Unplug the disk and restart it after it is killed. Kill, okay. I am very upset when I come up. After the installation is complete, restart and clean the environment ~ Headphones are still blank. The driver can also recognize that there are headphones inserted, that is, there is no sound, the horn is sound. Changed a headset, the same symptom. Delete the driver and reinstall it several times. Nima is desperate !!!! The rest of your life can only be stored in other places !!!! How can Nima secretly look at [Harmony] in the dormitory !!!! Nima !!!! You want to reject me !!!!

However, we still cannot accept the fact that the interface is broken. I think we just installed Ubuntu on the machine recently. Will it be a ghost. Restart and enter ubuntu. Show mute directly, wipe success? What is the situation? After the mute is canceled, music is heard from the headset ~ Sex ~~ It is not a hardware issue. Let's go back to win and see if the driver is gone. It's Nima. Is that mysterious ?! What is the situation. I have reinstalled the driver several times, but I still haven't heard of it. When I cried, I went back to Ubuntu and set the sound for half a day. It seems that there are some exceptions in Ubuntu.

Simple headphones and external devices are all muted (separately set ). Go back to win and try again !~ It's actually normal. There are some magical events. Please come and ask for answers ~!~!~!

PS: win7 C disk on SSD. D. The E disk is mechanical. Ubuntu is 20 GB at the end of the mechanical disk, and the startup of Ubuntu is also installed on the mechanical disk. Solid State boot directly into win, mechanical boot out of ubuntu screen. This is almost the case.
