Public bug reported: With the -45 kernel, sound output and input are unavailable. Output shows a Dummy device, no Input devices. This is a regression from the -40 kernel where the Output was working (no Input though). Attempted to use SOF, i.e. the fix mentioned in https://github.com/thesofproject/linux/issues/1877 This results in system freezes, failed boots, and failure to wake from sleep.
