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.
