Adjust the sound size in the command line-Linux general technology-Linux technology and application information. The following is a detailed description. First of all, I would like to thank haibian ).

I used MagicLinux, a Chinese ora version (I think it is). When I first installed it, there was no problem. Then I upgraded the system. Today, when I saw the potato, I found that the sound was too small to maximize. Then I found that the speaker in the lower right corner was gone. This was depressing. In the chat room, the pandatv online told him that he told me to use AlsamixerYou can try this command if you need it.
