I read this entire bug report and I added the FWUPD PPA and followed the directions. I own an Oppo Digital HA-1 desktop DAC and headphone amplifier. After unplugging it, shutting down, booting up, logging in, plugging it back in, I can not see my HA-1 in sound devices and it is stuck at DSD 12.288 MHz. I can not hear audio using it and my Sennheiser HD-800 headphones.
