The device seems to register properly: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: tegrahda [tegra-hda], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: TK1 [NVIDIA Tegra Jetson TK1], device 0: RT5640 PCM rt5640-aif1-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 Would you mind sharing the procedure how you test this? I tried various incantations of this sort: $ aplay -D hw:0,3 /usr/share/sounds/alsa/Noise.wav or $ aplay -D plughw:0,3 /usr/share/sounds/alsa/Noise.wav to no avail. Thierry
