> netbsd-nuc# audiocfg list 1 > 1: [*] audio3 @ uaudio1: USB audio Hi Ramiro, this is on a rpi4, isn't it? I'm curious, don't you have problems (system freezes) using usb audio with xhci (when audio is used for a while, not instantly)? By the way, there is a pretty active ham radio community on sdf.org. I recommend you to ask for an account there (if you are not already a member) and post your experience with netbsd on the bboard's HAMRADIO list. I'm not a ham myself, but I've good memories at a friend's house before the internet took over, and I check often that list to see what gizmos they use now. Regards. adr
