Dummy output with Celeron Silver audio

[Chris Hall]

Built in speakers have alsa driver as sof-audio-pci-intel-apl, but there is no sound. I believe the CPU sound unit is essx-8336. Many people have reported similar problems, with the system sound being "dummy output". My bluetooth ear buds do work. Endeavour-OS and Fedora 39 live images do work with this machine, as does the Win 11 dual boot, so the hardware works. Will this problem be fixed in version 24.04?
