Solve the problem of using the volume control shortcut for a laptop in Linux-Linux general technology-Linux technology and application information. The following is a detailed description. I am a Lenovo E255 notebook. When I installed the SUSE operating system, I found some problems with the volume control of my notebook in Linux. Later I installed Ubuntu and found that the problem still exists.

Mainly:

1. The volume control Master is invalid. You can adjust PCM to adjust the volume.

2. The volume control shortcuts such as Fn + F3/Fn + F4 in the notebook are controlled by the Master by default, resulting in invalid shortcuts.

Although PCM can be used to adjust the volume, the shortcut key is inconvenient. Today, the shortcut key problem can be solved. You can set it in "Preferences"-"sound effects" and select PCM.
