4.2.1 Audio
RB5 provide below interface for audio.
 One 4 data bit PCM/I2S with 6 wires: CLK, FS, D0~D3, are connected directly to the
QRB5165 SoC. These signals are driven at 1.8 V
 2 WSA8815 amplifiers are on-board and 2 pairs of speaker signals are routed to LS2.
 1 digital mic on development board
 3 pairs of DMIC signals are routed to LS
4.2.2 Stereo speaker
The speaker signals are routed from the 2 on board WSA8815. The signals are:
