[Alsa-user] Talking with alsamixer from command line

[Samuel Lê <sam...@gm...>]

Hi!

I currently run alsamixer from command line by running the command
alsamixer, and I can manually change the volume or mute my loudspeaker.
What I would like to do is controlling this with one command.
For example, running the following to increase the volume by two units:

alsamixer --volume 2

Basically I would like to change the volume in one command, and to
mute/unmute with another one, but I haven't found how to do it.

Can someone help?

Thanks!
Sam
