[linux-audio-dev] How does one alter the main mixer volume (or any other mixer level) in ALSA from a command line (via a simple system call)?

[Ivica Bukvic]

Hi all,

I have this small question:

Is it possible (I presume it is) to alter mixer settings in Alsa by
invoking some kind of a system call using shell (i.e. how the RME hdsp
can have its stuff altered)?

If so, what is the range of values that describe the loudest and softest
levels?

Finally, are these levels standardized?

Any help on this matter is greatly appreciated! Thank you! Sincerely,

Ico
