Hello, I got the same problem with the Schiit Audio Fulla 3 and the kernel 5.10.8 on Fedora.
But I got no problem with the Kernel 5.4.59 on Raspbian. Kurt Bonatz reported a problem with the 5.4.0. Maybe there is a difference in audio stack between Ubuntu and Raspbian. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887210 Title: USB DAC/AMP unselectable from Sound Settings and crashes alsamixer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1887210/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
