Public bug reported:
My sound card stopped being recognized suddenly today. lspci shows the
card, but alsa and pulseaudio don't see it. I verified that the kernel
modules are installed.
I noticed this today when I logged on and the only audio device was the
dummy device. I tried the various fixes I found online for this, but
nothing worked. I haven't made any changes to any audio packages
manually, but I have had automatic updates over the last few days which
may have caused this.
