I balieve this is the purpose of outputs.master - it sets the volume for multiple widgets; outputs.master.slaves says which. See azalia(4). > Now I just manually changed each inputs.dac alone. You are not supposed to tweak these controls directly; that's mixerctl does, and it requires root privileges. Try to set your controls with sndioctl as a regular user.
