An embodiment of an audio controller device includes technology to control an output of a first audio signal from an audio output device in a human interface frequency range, where the human interface frequency range includes frequencies audible to humans, and control an output of a second audio signal from the audio output device in a device interface frequency range independent from the output of the first audio signal, where the device interface frequency range includes frequencies above an upper limit of the human interface frequency range. Other embodiments are disclosed and claimed.
