Public bug reported: On an HP 15z-fc000 laptop with Realtek ALC236 audio, on Ubuntu 22.04.3 with HWE kernel 6.2.0-34-generic, after doing a warm boot (i.e., "Restart" from the menu" or "sudo reboot"), no sound will be able to play. Doing a cold boot (i.e., "Power Off" or "sudo poweroff" and then pressing the power button to turn it back on) will make it start working again.
This bug is a regression caused by commit 5aec98913095 ("ALSA: hda/realtek - ALC236 headset MIC recording issue"). I've already worked with upstream to get a fix for this bug into the mainline kernel, which has since landed as commit 69ea4c9d02b7 ("ALSA: hda/realtek - remove 3k pull low procedure"), with commit 46cdff2369cb ("ALSA: hda/realtek - Remodified 3k pull low procedure") as a follow-up. To fix this bug, those two commits just need to be cherry-picked into Ubuntu's kernel.
