The RPi built-in sound chips don’t have a “master volume” control, and as a result, you must control the volume via software. I guess the RPi views itself as a preamplifier (preamp) and volume controls would be supplied down stream. ALSA provides a software volume control using the [http://alsa.opensrc.org/Softvol softvol] plugin. | The RPi built-in sound chips don’t have a “master volume” control, and as a result, you must control the volume via software.
