I just purchased a Kingston HyperX Amp USB soundcard[1]. The microphone input does not work correctly in Alsa, though it is listed as a capture device. $ arecord -l <snip> card 1: Amp [HyperX Amp], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 <snip> When I try to choose it with alsamixer I get an error: $ alsamixer -c 1 cannot load mixer controls: Invalid argument This is on Debian Sid with Linux 5.4 $ uname -a Linux fireball 5.4.0-trunk-amd64 #1 SMP Debian 5.4.2-1~exp1 (2019-12-05) x86_64 GNU/Linux $ lsusb <snip> Bus 001 Device 010: ID 0951:16d8 Kingston Technology HyperX Amp <snip> I am not sure how to debug the problem further, but I would appreciate any assistance.
