Hello. I’m trying Getting-started with ReSpeaker_6. Step1 and Step2 seems working correct. But “arecord” doesn’t work at step3. I also tested with audacity but it seems microphones aren’t recognizing any sounds. Below is the command which I’m running.
arecord -Dac108 -f S32_LE -r 16000 -c 8 a.wav
Is there anything I have to configure to record with microphones? I’m using “Raspberry pi 4 Computer Model B”.
Please ask me If you need more information. Thanks.
Have you got any solution for this problem? I’m also facing this problem. I connected Respeaker 6 mic circular array to my rasberry pi 4B and I did same as the documentation. I tried to record using ‘arecord -Dac108 -f S32_LE -r 16000 -c 8 a.wav’ command there is an error came like this - ‘arecord -Dac108 -f S32_LE -r 16000 -c 8 a.wav
ALSA lib pcm.c:2666:(snd_pcm_open_noupdate) Unknown PCM ac108
arecord: main:831: audio open error: No such file or directory’
is there any solution for this problem?
You may need to install or update the seeed-voicecard driver.
