do you mean node 0x14 is the subwoofer ?
you can use hda analyzer to mute and unmute node 0x14 to find out
whether it is the subwoofer and internal Mic is node 0x12
[ 5.445875] autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker
[ 5.445876] speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
[ 5.445877] hp_outs=2 (0x15/0x16/0x0/0x0/0x0)
[ 5.445877] mono: mono_out=0x0
[ 5.445878] inputs:
[ 5.445879] Mic=0x19
[ 5.445880] Internal Mic=0x12
use hda jack sense test to verify the three jacks are 0x15, 0x16 and
0x19
if the above nodes are correct, only pincap of nodes 0x18 and 0x1a support OUT
which may be the missing speakers
the driver create bass playback switch at the node with higher sequence
number , so you need to adjust the sequence number so that subwoofer
node has higher sequence number then the stereo speakers node
Control: name="Bass Speaker Playback Switch", index=0, device=0
ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Control: name="Speaker Surround Phantom Jack", index=0, device=0
use early patching instead of dynamic reconfig since dynamic reconfigure
keep on create inputs

Title:
[Alienware 18, Realtek ALC668, Speaker, Internal] Playback problem
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
Bug seems similar to another reported bug with Alienware 18 laptops.
It should be Realtek ALC3661 however it shows up as ALC668. Sound only
comes out of 1 Channel, which appears to be subwoofer. Unlike the
other bug, closing the lid appears to have no effect on sound.
When doing the bug test, it said sound would alternate between 2
channels, however I only heard one consistent sound. It did not
alternate. I believe it is playing from the subwoofer only. I would
love to know more about how to route the sound to the proper speakers.
I attempted modifications to daemon.conf in pulse and .asoundrc but
have not found the correct configuration yet.
This laptop is equipped with 2.1 Surround and should play sound
accordingly. Also, alsamixer only shows (1) speaker control, whether
this is normal I am unsure.
