-Testing of the sensorboard requires, that all other PCB's are working properly. The 10-pin ribbon cable must be connected to the Adapterboard and the single Audio cable to J5 must be connected to the Cubieboard Headphone Connector (GND comes via the ribbon cable). It is recommended to perform the electrical tests **before** sealing the POM-block. A loudspeaker is connected via a CINCH cable to J4. Take care that the outer conductor of the CINCH-connector is isolated from the metal housing, otherwise the audio amplifier for the Vario does not work properly. The Audio Synthesis is made on the Cubieboard using **ALSA** (Advanced Linux Sound Architecture). The Volume can be controlled with **alsamixer** from the shell. Persistent storage of the alsamixer-settings can be made with **alsactl store**. Some components (MS5611, MPU-9150) do not offer direct access to their terminals, therefore the testpoints can be located more far away as expected.
