I've installed the respeaker pi hat module to my Rpi0W using sudo apt-get update sudo apt-get upgrade git clone https://github.com/respeaker/seeed-voicecard.git cd seeed-voicecard sudo ./install.sh reboot but cannot test whether it works - The tutorial states I can pipe the recording and play it as such arecord -f cd -Dhw:1 | aplay -Dhw:1 but this is not working? I guess my hardware is listed differently? but i can't figure out how i should make the same call above with my hardware list? pi@raspberrypi:~ $ aplay -l && arecord -l **** List of PLAYBACK Hardware Devices **** card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA] Subdevices: 7/7 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 card 0: ALSA [bcm2835 ALSA], device 1: bcm2835 IEC958/HDMI [bcm2835 IEC958/HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: ALSA [bcm2835 ALSA], device 2: bcm2835 IEC958/HDMI1 [bcm2835 IEC958/HDMI1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: seeed2micvoicec [seeed-2mic-voicecard], device 0: bcm2835-i2s-wm8960-hifi wm8960-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 **** List of CAPTURE Hardware Devices **** card 1: seeed2micvoicec [seeed-2mic-voicecard], device 0: bcm2835-i2s-wm8960-hifi wm8960-hifi-0 [] Subdevices: 0/1 Subdevice #0: subdevice #0 tutorial: http://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/
