use hda-analyzer to check whether node 0x10 mono pin complex is the
subwoofer or not
1) set pin-ctls of node 0x10 to OUT
2) check the power setting of node 0x10, 0x1a, 0x19 are D0
3) either connect node 0x19 to node 0x13
or node 0x1c
4) if you connect node 0x19 to 0x1c
a) unmute amp-out and change the volume slider of node 0x1c
b) unmute the amp-in of either node 0x13 or node 0x14 in node 0x1b and
keep the other amp-in mute
c) ensure the power setting of above nodes are D0

Title:
[HP ENVY 4 Notebook PC, IDT 92HD91BXX, Speaker, Internal] Playback
problem
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
The subwoofer on my laptop is not shown by default in the audio
settings. When i try updating the alsa-base.conf file, I can get the
subwoofer to appear, but its still disabled. I can manage to "enable"
the subwoofer by making changes to both the /etc/pulse/daemon.conf and
/etc/pulse/default.pa files, however the sound is then full of noise
and somehow distorted. Finally, I have beats audio on my laptop, which
of course a cannot use.
