On this answer: https://askubuntu.com/a/481831/307523, I found this comment I wrote last year: March 5, 2017 - Just to confirm this activates the sub-woofer for the Dell Inspiron 17R 7720 SE in Ubuntu 16.04.
Firstly you will need to install alsa-tools & alsa-tools-gui from either the software center or from terminal.
sudo apt-get install alsa-tools alsa-tools-gui
Open HDAJackRetask
Select the IDT 92HD91BXX codec
Check the “Show unconnected pins” box (the internal speakers do not show as connected)
- Remap 0x0d (Internal Speaker, which is your Front side) to Internal speaker.
- Remap 0×10 (“Not connected”, which is the subwoofer) to “Internal speaker (LFE)” ```
``` Select “Install boot override” to save the settings to apply at boot time. Reboot. When it comes back, you should have full sound from all speakers.
Note: Option 2. was removed due to new testing by alfC. It used to say:
- Remap 0x0f (“Not connected”, which is the under-display speakers) to “Internal speaker”
