No, just the three+alsamixer will not work. You also need to
814: |= 400
824: |= 400 CPCAP_REG_RXCOA : CPCAP_BIT_PGA_CDC_EN 81c: |= 006 CPCAP_REG_RXOA : CPCAP_BIT_A2_LDSP_L_EN / CPCAP_BIT_A2_LDSP_R_EN
You can set those using sudo aplay -D plughw:CARD=Audio,DEV=1 /usr/share/sounds/alsa/Front_Left.wav ... but that will do bad stuff to the rest of the bits.
You might find this useful:
watch 'cat /sys/kernel/debug/regmap/spi0.0/registers | grep "0800\|0804\|0808\|0814\|0818\|081c\|0820\|0824\|0828"'
Good luck, I need some sleep,
Pavel
