** Description changed: I was running Ubuntu 20.04 flawlessly, but when I got an update from the kernel 5.11 to the 5.13, then I got the dummy output e no sound comes out from my speakers or mic. I made a fresh install without updating and I got the sound back. When I update the issue comes back. - The same problem occurs on other distros with the 5.13 kernel and with the 5.15 as well. + The same problem occurs in other distros with the 5.13 kernel and with the 5.15 as well. + I've seen occur in Pop!_OS both 20.04 and 21.10 and in Ubuntu 21.10 with the related kernels. No troubleshooting fixed the issue. When my sound was working the name of my audio device was chtnau8824.
