From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Support: No Sound on internal subwoofer (LFE) Linux Mint (feddit.nl)

Hi al, I just did a fresh install of linux mint and I don't have any audio on my internal subwoofers. Dell XPS 9500. I made a post about it on the linux mint forums, which contains more info and "progress" but no luck so far.

I have already found and set my subwoofers to the internal speakers LFE via HDAJackRetask now I need to have them actually get a signal. I hope one of you amazing peeps is able to help me.

Edit:

Okay it has been a productive evening. So from reading this thread on bugzilla.kernel.org it seems that the subwoofers are working and actually are playing audio. The speaker fix seem to have been added somewhere before kernel 5.15 (This is for the 9500, which sets the same quirk as is set for the 9510.) What it currently looks like what the problem is that there is a high pass filter for the tweeters which also get applied to the subwoofers. Which means that the subwoofers are effectively producing no output even tough they are getting an input. I currently have no clue how to mitigate this. The bugzilla.kernel.org thread is really worth reading!

If multiple distro families don't work, might be a case of the hardware not being supported yet.

I know it has been fixed in a kernel patch for the other 95x0 models and should be ready in some 6+ kernels but I'm not sure for the 9500
