			You need to add pwfeedback to the sudo defaults, there are two ways to do it, the latter is probably better

			=== By editing /etc/sudoers ===
			Run visudo (allows editing sudo config safely)
	sido visudo		sido visudo

	Find 'Defaults' section:		Find 'Defaults' section:
	Defaults env_reset		Defaults env_reset

	Add pwfeedback to 'Defaults'		Add pwfeedback to 'Defaults'
	Defaults env_reset,pwfeedback		Defaults env_reset,pwfeedback

			=== By adding a special sudoers.d custom rule file ===
			Alternatively you can also add the following file
			/etc/sudoers.d/enable-pwfeedback
			Containing this string:
			Defaults pwfeedback

Make audio sound good

Theleruby — Fri, 21 Aug 2026 09:56:07 GMT

Theleruby moved page Make audio sound good to Using EasyEffects to filter out muddy audio and make things sound good without leaving a redirect

New page

Roughly emulates realtek powerful + creative x-fi mb5 crystallizer, bonus is this works without having to use a USB port on a SoundBlaster

Install easyeffects using your package manager, e.g:
sudo rpm-ostree install easyeffects
systemctl reboot

You should then import this effect configuration .json file (copy the contents, save it as a .json file, there's an import button in easyeffects to import a preset from a .json file)
