During the installation, we are supposed to check the sound card by pressing ‘arecord -L’ to obtain a certain output like shown below,
| pi@raspberrypi:~ $ arecord -L | |
|---|---|
| null | |
| Discard all samples (playback) or generate zero samples (capture) | |
| jack | |
| JACK Audio Connection Kit | |
| pulse | |
| PulseAudio Sound Server | |
| default | |
| playback | |
| ac108 | |
| sysdefault:CARD=seeed4micvoicec | |
| seeed-4mic-voicecard, | |

| dmix:CARD=seeed4micvoicec,DEV=0 | |
| seeed-4mic-voicecard, | |
| Direct sample mixing device | |
| dsnoop:CARD=seeed4micvoicec,DEV=0 | |
| seeed-4mic-voicecard, | |

| hw:CARD=seeed4micvoicec,DEV=0 | |
| seeed-4mic-voicecard, | |
| Direct hardware device without any conversions | |
| plughw:CARD=seeed4micvoicec,DEV=0 | |
| seeed-4mic-voicecard, | |
| Hardware device with all software conversions | |
| usbstream:CARD=seeed4micvoicec | |
| seeed-4mic-voicecard | |
| USB Stream Output | |
| usbstream:CARD=ALSA | |
| bcm2835 ALSA | |
| USB Stream Output |
However, the output that I have received is as shown below,
It basically shows that I don’t have the ASLA soundcard, and I cant move on to the sound localization process. Please show how can I move forward, thanks!
