Audio on Windows works perfectly, no issues. No option in BIOS to disable.

Speakers are not muted in GUI or in Alsamixer, though Alsamixer pulls up HDA Intel HDMI first, but when switching to HDA Intel PCH nothing changes.

I have installed, updated, uninstalled, disabled and enabled PulseAudio

Output of lspci -v | grep -A7 -i "audio":

Any ideas? I think I've read every forum post related to this computer and audio in general, and still hit a wall.

  • I have had similar issues with Linux on various Chromebooks. It is a pain in the butt. Look over this, it may have a solution: https://askubuntu.com/questions/974073/no-audio-on-acer-chromebook-14-under-ubuntu-17-10 Yes, I know it says Chromebook, but the commands work on all of Linux. – Logan Mar 30 '22 at 16:11

not sure if it will help a Latitude but add this parameter to the kernel command line:

snd_intel_dspcfg.dsp_driver=3

I had to do this on a Dell Venue Pro 11 and the sound worked perfectly. It is for kernels after 5.10 as a change was made to the drivers. Source: https://fedoraproject.org/wiki/Changes/SofDefaultForIntelLpe
