Public bug reported: Symptoms:
no hardware audio output device found by PulseAudio on eoan after I have updated the system yesterday. Works: linux-image-5.3.0-40-generic Does not work: linux-image-5.3.0-42-generic * I suspect this is somewhat related to the recent changes for SkyLake+ platforms between tags Ubuntu-5.3.0-40.32 and Ubuntu-5.3.0-42.34 (I am referring to the repo at <https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan>). * I am using the binary package from the Ubuntu repos, not a self-built kernel. * I can help with bisecting and testing if you like. If you like me to, I need a piece of advice: is <https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel> the proper up-to- date documentation for building my Ubuntu kernel from the sources in the git repo? What I have tried so far: I wanted to reload the sound module(s), so I ran the following command: $ pulseaudio -k ; sudo rmmod snd_hda_intel snd_soc_skl_hda_dsp snd_soc_skl_ssp_clk snd_soc_skl snd_soc_skl_ipc Then I ran: # modprobe snd-hda-intel I found the following in my syslog (not totally sure about when exactly this happened – before or after the rmmod/modprobe): (see attached file) Output of ‘sudo lspci -vvnn’ (warning: on 5.3.0-40-generic! Because I am working in parallel and need a functioning audio setup right now; I can try this on another kernel in the evening if absolutely necessary, but this should suffice): (see attached file) If more information is necessary for proper debugging, please give me some instructions what to do.
