asound config with multiple inputs each having a softvol, and a combined equalizer

Hello,

Though next is still work in progress, a quick share of my also setup.
Also installed amixer-webui to control the (softvol and equal) values.
Otherwise use alsamixer, or 'amixer sset [volname] [%-value]'.

Best regards,
Juno.
