Linux newbie here step 4 say edit a file “etc/modprobe.d/alsa-base.conf” as root WHERE is this file?
and how do I change the kernel parameters?
@Kim_Brady_Eyben Would you be able to link the guide as there are lots of them for all the different distributions.
Nevermind, I found what you were talking about. The file is in the path you specified, /etc/modprobe.d/alsa-base.conf. A quick way to add it is to open a root shell sudo -s and run echo "options snd-hda-intel model=dell-headset-multi" >> /etc/modprobe.d/alsa-base.conf and then reboot. That should do what they are referring to.
@Kim_Brady_Eyben To change kernel parameters you have to change your grub settings. Assuming you are using a distro with grub (most of them use grub, popos doesn’t for example).
There are two options to do this, one through terminal and one through GUI.
Terminal: edit /etc/default/grub file. Everything after GRUB_CMDLINDE_LINUX_DEFAULT= are the kernel parameters. BE VERY CAREFUL EDITING THIS FILE, YOU CAN END UP WITH A NON BOOTING SYSTEM.
Then you have to update the grub config with this command sudo grub-mkconfig -o /boot/grub/grub.cfg.
Reboot
GUI:There are many GUI options available, the one I use is grub-customizer. Install it with your package manager or store (depending on what distro you use).
Then launch the app, in the General settings tab you will see kernel parameters. Edit it and click top-left on save.
Reboot
