Some of my speakers are not working and hence sound output even in VLC is below average. Bottom firing speakers are mediocre. I found an answer on this site for a Dell laptop, and the config was a little different which confused me.
I am new to Linux and just dual-booted my laptop for college purposes and coding.
The solution I found uses HDAJackRetask GUI from the alsa-tools-gui
package.
In the application I ticked show unconnected pins and attempted to use trial and error to find a working combination. I had the B/O front firing speakers working through overriding and setting all pins as internal speakers, but could not find a working configuration for the subwoofer. Can anyone suggest a suitable configuration?
I'm using Ubuntu 17.04.

After clicking through a bunch of links I found a solution that worked for me (HP Pavilion with Ubuntu 20.04, bass speaker was not working). The following answer is copied verbatim from https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1648183. I'm copying it here since this link showed up first when I searched. I'm intentionally leaving in the usernames since I am not the one who solved this problem:

I've managed to fix this problem on my machine (HP Omen 15 running Ubuntu 17.04 using codec for Realtek ALC295 sound device). To fix the problem, I can do the following:
Install alsa-tools if not installed:
Create and save a script in /usr/local/bin:
Run the script as root in a terminal to immediately fix the problem.
To run the script on startup, use cron with the @reboot command:
and then add line in crontab:
To run script on resume from suspend, copy the script to /lib/systemd/system-sleep
