Comment 26 for bug 1828136

According to the log of ls and aply -l, your audio hardware is recognized by the driver after booting up.

And alsa is ready to work, I can't find any problem here. I guess you could run 'aplay test.wav' to play sound after booting up without "sudo alsa force-reload"

you wrote "After rebooting I have no sound. My sound device doesn't show up at all in the mixer.", does it mean there is only a dummy output in the gnome-sound-setting?
