I note dracut package has been bumped to 050+suse.58.g0b998bee. Just checked it, and still segfaulting -- as above -- for both GCC-9 & GCC-10 builds. What's status on a fix here, if any?

[opensuse-kernel] kernel 5.6: baytrail hdmi audio not working
by Giacomo Comes 01 Apr '20

Hi, the new 5.6 kernel breaks the sound on my Intel Compute Stick (baytrail hdmi audio). command 'ls -l /sys/class/sound' shows: card0 -> ../../devices/pci0000:00/0000:00:02.0/hdmi-lpe-audio/sound/card0 controlC0 -> ../../devices/pci0000:00/0000:00:02.0/hdmi-lpe-audio/sound/card0/controlC0 pcmC0D0p -> ../../devices/pci0000:00/0000:00:02.0/hdmi-lpe-audio/sound/card0/pcmC0D0p pcmC0D1p -> ../../devices/pci0000:00/0000:00:02.0/hdmi-lpe-audio/sound/card0/pcmC0D1p timer -> ../../devices/virtual/sound/timer dmesg output contains: input: Intel HDMI/DP LPE Audio HDMI/DP,pcm=0 as /devices/pci0000:00/0000:00:02.0/hdmi-lpe-audio/sound/card0/input7 input: Intel HDMI/DP LPE Audio HDMI/DP,pcm=1 as /devices/pci0000:00/0000:00:02.0/hdmi-lpe-audio/sound/card0/input8 which is the same as with kernel 5.5, however with the new kernel there is no audio output and the kde audio applet shows no audio device. Is anybody haware of this problem? If necessary, I can bisect the kernel to find the commit that introduced the regression.
