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?)
