I have connected a usb microphone to the Raspberry but I can’t get it to work. In Windows it works perfectly but in Linux of the Raspberry there is no way.
sudo arecord -l:
**** List of CAPTURE Hardware Devices ****
card 1: Device [USB PnP Sound Device], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
It seems that it is recognized, but when trying to do a recording test using:
arecord --device=plughw:1,0 --format S16_LE --rate 44100 -c1 test.wav
Gives as an error:
ALSA lib pcm_hw.c:1829:(_snd_pcm_hw_open) Invalid value for card
arecord: main:830: audio open error: No such file or directory
