I have a StarTech ICUSBAUDIO7D https://www.startech.com/Cards-Adapters/Sound/USB-Audio/USB-7-Channel-Audio-Adapter-with-SPDIF~ICUSBAUDIO7D which I want to use the mic input on. Mostly I'm vague on the Alsa syntax for specifying devices and especially subdevices. My alsa-info output is at http://alsa-project.org/db/?f=d225395a5fefc44d18a4b055d35d630450113660 I bought this USB audio card originally to use with a Raspberry Pi and a guitar, now I'd like to record some nature sounds with electret mikes. I've never gotten recording with it to work at all, playback does work well. Using Alsa 1.0.27+1 under Raspbian Buster. -- ------------- No, I won't call it "climate change", do you have a "reality problem"? - AB1JX Cities are cages built to contain excess people and keep them from cluttering up nature.
