| Summary | Audio device: Intel Corporation Device 02c8: not detected | Audio device: Intel Corporation Device 02c8: not detected (snd_hda_intel.dmic_detect=0 works around) |
Adding snd_hda_intel.dmic_detect=0 to the GRUB_CMDLINE_LINUX_DEFAULT entry in /etc/default/grub, running update-bootloader, and rebooting appears to work around this issue. That's a bit tricky and took me a fair bit to find. Can the kernel somehow handle this itself?
