Hi all. I just bought an external USB audio card. I plugged it into the USB port of my PC and plugged a 3.5mm jack microphone into the `mic' input of the card. It is shown in lsusb:
$ lsusb Bus 002 Device 005: ID 17ef:602e Lenovo Bus 002 Device 003: ID 046d:c312 Logitech, Inc. DeLuxe 250 Keyboard Bus 002 Device 002: ID 0438:7900 Advanced Micro Devices, Inc.

But then, when I try to record, no sound is recorded. I do: $ sox -t alsa hw:2,0 output.wav , or $ arecord -f S16_LE -D hw:2,0 -r 96000 test.wav , or also within Audacity. But nothing, my voice is not recorded. Please help whoever can. Thanks, Rodolfo
