Chrome OS has a native sound manager for accessing your sound card’s settings. It is “Alsamixer“, a graphical mixer program for the Advanced Linux Sound Architecture (ALSA). It is used to configure sound settings and to adjust the volume.
It has a ncurses user interface and does not require the X Window System. It supports multiple sound cards with multiple devices. You get to control Master Volume, Headphone volume, Speaker, PCM, and Mic. There is “Mic Boost” as well.
How to Access Alsamixer on Chrome OS

Now, type shell and hit enter, and go to shell prompt.
