Can you post the output of always-info.sh (kernel without quirk, model=auto
)?

Take a look at 92HD81 datasheet

2.1.Port Functionality
2.2. Mono Output
2.19.BTL Amplifier High-Pass Filter
        The high pass filter is enabled by default with a cut-off frequency
of 300Hz
2.23.2. “Playback Path” Port Behavior

Figure 8.  Functional Block Diagram

If your note book really have 5 speakers and node 0x0f is the rear speaker
, the sequence number should be 1 instead of 0 by pin fixup

Do the headphone , Mic jack and internal Mic work as expected ?

subwoofer is most likely at mono pin node 0x10

use hda-analyzer to change Pin-ctls to OUT and connect node 0x19 to the
audio output with speaker playback volume control

Either 0x0d or 0x0e is the front speaker

Use early patching to fix the pin default

Node 0x10 [Pin Complex] wcaps 0x400500: Mono
  Pincap 0x00000010: OUT

    Conn = Unknown, Color = Unknown
    DefAssociation = 0xf, Sequence = 0x0
  Pin-ctls: 0x00:
