Mmh. Have you tried using this device with same configuration with arecord ?
You could try like this:
Code: Select all
arecord -Dsysdefault -r48000 -c1 -fS16_LE test.wav
The error you have is "no such device", which is error code -ENODEV from ALSA.
If I read ALSA online documentation, I see this:
This error can happen when device is physically removed (for example some hotplug devices like USB or PCMCIA, CardBus or ExpressCard can be removed on the fly).
You seem to use an USB card, but well, I just tried on my laptop with a Logitech USB headset with success.
I have a Pi A+, a Pi B+ and a PiZero at home, I can try on these, eventhough you use Pi3 and its different.
Can you tell me which distribution you use ? Raspbian ?
