I can confirm I'm having the same problem with a similar HP Pavilion model under Fedora 27. There is no audio from the built in speakers but pavucontrol shows audio is being played. Verified nothing is muted in alsamixer.

Headphone jack works as expected.

I can confirm I'm having the same problem with a similar HP Pavilion model under Ubuntu 16.04.There is no audio from the built in speakers but pavucontrol shows audio is being played.

Headphone jack works as expected.It is muted until I plug headphones in then the speakers mute. Removing headphones unmutes the speakers but no sound through them. I also checked on alsamixer and nothing is muted (except as described above.)

I got my new HP Pavilion 15-cc055od laptop to play sound out of the internal speakers in Xubuntu 16.04.

After days of googling I tried different remedies unsuccessfully until I stumbled unto this website:

https://launchpad.net/~diwic/+archive/ubuntu/hda

HD audio related stuff:David Henningsson
whose advice was very sound. I downloaded alsa-utils-gui using synaptic and used the following utility:

 hdajackretask - retask jacks on HDA Intel hardware

I used it to remap connections willy nilly until now sound works out of the internal speakers. Pulse Audio Volume Control says the playback is from speech-dispatcher. But I don't care.

Confirming the same issue on hp pavilion 15-cb045wm. Was not able to fix the problem with hdajackretask. Fix outlined here did not fix the issue: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1648183

Changing model to these failed to fix the issue:
hp
generic
auto

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[M I (mellowirony)]

Same issue, HP Pavilion 15-cc178cl.

Tried:
- checking that speakers aren't muted in alsamixer & pavucontrol
- renaming /etc/modprobe.d/alsa-base.conf
- model={generic,auto,hp} in /etc/modprobe.d/alsa-base.conf
- adding these lines to ~/.config/pulse/default.pa: https://askubuntu.com/a/1068198 (this caused pulse to fail to start)
- remapping each output pin to "Internal Speakers" in hdajackretask

Have not tried:
- uninstalling and reinstalling alsa and pulse (this appears to want to uninstall ubuntu-desktop--is that expected?)
