I'd guess one of the numbers is off a little. I just got this to work on my Pinebook Pro's internal microphone. First time I'd tried it. Well, it took a few tries adding stuff to correct error messages. arecord -Dhw:0,0 -f S16_LE -c2 -t wav test1.wav Try using a higher card number, then higher device numbers and pay attention to the error messages. There's probably a way to do it that you just haven't found yet. It's quite possible it's a HID (Human Interface Device) which adds a layer of addressing.complexity. I have a pair of bluetooth earbuds which are HID, they suppposedly have a microphone. lsmod | grep snd should show at least something, that's showing kernel modules to deal with Alsa sound. You might have to insmod one the first time. On 4/27/21, Knard <knard@xxxxxxxxx> wrote: > Hi, > > I just bought an USB headset and the mic is not working.
