No sound on subwoofer

Question

I have a HP Pavilion dv7 4011eg Notebook. It has a Beats Audio 2.1 System. It uses a IDT HD Audio Codec. My problem is that I get no sound on the subwoofer. I experienced the same problem with Windows having the codec not installed, so is there a way to install it? Ubuntu 15.10

Audio codecs are pre-installed and like almost all other drivers are part of the linux kernel. Does this help? http://askubuntu.com/questions/53802/subwoofer-sound-preferences-problem?rq=1 — mchid, Apr 01 '16 at 15:26

Fixed it now!

I installed the program hdajackretask and overwrote the pin ID 0x10 with Internal Speaker (LFE). Install boot override and all works fine.

Note: as of Ubuntu 13.10, hda-jack-retask is part of alsa-tools. Just install the alsa-tools-gui package from the regular archive and start hdajackretask.

sudo apt-get install alsa-tools-gui

Also edit the following file: sudo gedit /etc/pulse/daemon.conf Uncommment and change the values of these lines:

enable-lfe-remixing = yes default-sample-channels = 3 default-channel-map = front-left,front-right,lfe Second, edit the following file: sudo gedit /etc/pulse/default.pa

Add the following line to the end:

load-module module-combine channels=3 channel_map=front-left,front-right,lfe

Open a terminal and then run the following command:

alsamixer

Press F6, use your up/down arrow keys to select your sound card and then press ENTER.

Press F5.

Use your right arrow key to select the "automute" channel and use your down arrow key to toggle this to "disabled".

Now, use your right/left arrow keys to locate any channels that say MM.

Select any channel that says MM and press your M key to toggle MM to 00.

If you see a channel for your subwoofer, adjust the volume. Use your up/down arrow keys to raise or lower the volume.

Alternatively, you can use your W key to raise the volume and you can use your X key to lower the volume.

Press ESC to exit alsamixer.
