I recently replaced my previous Linux laptop (a Dell XPS) with a HP Envy x360 (13-b0074TU) and setup Windows to install whatever firmware or BIOS updates were available, and then made a Fedora bootable USB and proceeded to wipe the drive and install.
The installation went smoothly, however after a reboot, I realized audio isn't working, I can see that the microphone is detected and working, and an external USB headset is working too, as is the headphone jack, however the internal speakers are not.
From what I can see it's a firmware issue, as searching around fourms and lore.kernel.org, it can be a firmware bug.
Checking logs, the most I can kind of see is this:
Mar 19 01:48:41 fedora kernel: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.1: Error: ACPI _DSD Properties are missing for HID CSC3551.
Mar 19 01:48:41 fedora kernel: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.1: error -EINVAL: Platform not supported
Mar 19 01:48:41 fedora kernel: cs35l41-hda: probe of i2c-CSC3551:00-cs35l41-hda.1 failed with error -22
This is clearly a semi-recognized issue as documented in this thread on the HP fourms: https://h30434.www3.hp.com/t5/Notebook-Audio/No-sound-from-internal-speakers-using-Linux/td-p/847805...
