Intel Graphics - Best practices and settings for hardware acceleration?

I agree with the thanks, but note some errors in the feedback provided.
As I stated in the other necro thread where this exact same feedback was posted.

sudo grub2-mkconfig -o /etc/grub2.cfg
sudo grub2-mkconfig -o /etc/grub2-efi.cfg
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

These three commands do exactly the same thing

@amidevous

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

This command overwrites a pointer file used to redirect grub to the actual grub.cfg file located at /boot/grub2/grub.cfg and will mean the user MUST manually repeat that command with every kernel update.

To recover from this error the user must first remove 2 files then reinstall grub2-common to recreate those files properly.
sudo rm /boot/grub2/grub.cfg /boot/efi/EFI/fedora/grub.cfg
sudo dnf reinstall grub2-common (which will recreate the files just removed with proper content.)

Fedora 36: no sound coming out of HDMI, Intel i5 8250U, setting intel_iommu=on,igfx_off in grub doesn't help

UPDATE: in the end, the only way to make the sound out of my HDMI is to use the HDaudio legacy driver by adding the options snd-intel-dspcfg dsp_driver=1 in the /etc/modprobe.d/snd-intel.conf file. Then running sudo dracut --force and reboot. However, with the HDaudio legacy driver, DMIC wouldn’t work which is the expected behavior. Fedora 36 default setting is options snd-intel-dspcfg dsp_driver=2 (SST driver). No matter what you do, the HDMI audio will not work, ever. SOF driver, options sn…
