Hi,
The system registers two sound cards, one for the HDMI monitor, one for the ADAU1761. The HDMI monitor is the default sound card. You can switch between sound cards in alsamixer by pressing F6. For tools like aplay or arecord you can select the sound card using the -D option. E.g. `arecord -c 2 -f S32 -r 48000 -D default:CARD=ADAU1761 test.wav`. The -L option will list the available sound cards.
