Dialog Semiconductor based IQaudIO boards
Our Dialog Semiconductor based boards (
Pi-Codec+ / Pi-CodecZero
) are general purpose sound
cards, playing back stereo audio but also recording audio too.
As it’s a general purpose audio card with multiple inputs and output options and several volume
controls the basic configuration is more complicated than our standard playback only products. The
information below can be used to check that audio playback is working as expected.
CONFIGURE THE CODEC BOARD TO PLAYBACK AUDIO THROUGH THE AUX OUT AND MONO SPEAKER.
From the Raspberry Pi’s command line, run
alsamixer
. If you have more than one sound card installed
you may have to select which is being controlled by pressing the F6 key.
Note the following labelling differences between the software control and board silk screen.
a) Headphone = AUX OUT (volume)
b) Lineout = MONO SPEAKER (volume)
c) AUX = AUX IN (recording level)
Enable AUX IN LEFT channel
Enable AUX IN RIGHT channel
Enable Analog Digital Convertor (ADC) & Mixer level
