I am experiencing the same problem with a RODECaster Pro and (in my case) Arch Linux. The following log output is generated when I connect the RODECaster via USB:

The RODECaster shows up in the list of cards that ALSA knows about, but PulseAudio can't find a working profile and gives up. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1877726 Title: [HDA-Intel - HD-Audio Generic, playback] USB sound with Rodecaster Pro not working Status in alsa-driver package in Ubuntu: Confirmed Bug description: Please see https://askubuntu.com/questions/1229085/ubuntu-with-rodecaster-pro-usb-soundcard/1236257#1236257 for most background. tl;dr: - The Rodecaster Pro is a USB audio standard compliant device - lsusb sees it, but alsa cannot use it - trying the exact same setup with a Scarlett 2i2 USB device works (with some caveats, see the mentioned post) Somehow the Rodecaster is ignored by Alsa. I am more than happy to help debug.
