I would have thought any device using the generic USB audio module would have worked. I’ve tried ensuring all of the ALSA and PulseAudio related packages are installed. I am using Ubuntu Server 21.04 with all system updates. Is anyone aware of any USB audio devices that are known to work, or likely to work, with ALSA? I am aware that audio via HDMI on Radeons has been met with success for others, but I’d like to first exhaust a standalone USB audio device. Because the board has only one PCI express slot which I intend to use for a VGA, I’ll need to explore the possibility of USB audio. I am doing some development on a SiFive Unmatched development board.
