The relevant quirks here are:
model=dell-bios (default in driver source code)
model=dell-3stack
model=3stack
model=laptop doesn't make any sense; it's not even defined or relevant for this codec id (0x83847616) and quirk table (stac927x_cfg_tbl[]).
Please try these steps: completely remove all snd-hda-intel model quirks from your /etc/modprobe.d/* and reboot. If sound remains inaudible, readd a quirk for dell-3stack and reboot.
