How to activate subwoofer in Inspiron 17r?

rated 0 times [ 2] [ 0] / answers: 1 / hits: 12910 / 2 Years ago, sun, february 13, 2022, 3:13:51

I have a Dell Inspiron 17r, after a fresh install of 12.10, the subwoofer seems to be not utilized. No sound comes from it and in the Sound Control Panel the settings appear grayed out (see screenshot). How can I activate the subwoofer?

no subwoofer

I tried adding the line

options snd-hda-intel model=dell

in the file /etc/modprobe.d/alsa-base.conf and

enable-lfe-remixing = yes

default-sample-channels = 3

in the file /etc/pulse/daemon.conf, but still doesn't work.

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”
