Where can I find gnome-alsamixer on ubuntu 20.04?

I'm preparing new setup for my work with ASUS PRIME H310M-F R2.0 Mainboard. The problem is front audio panel is not working. And I googled people telling try with gnome-alsamixer. But I can't find it on ubuntu 20.04.

Install alsamixergui using:

sudo apt install alsamixergui

• You can install qasmixer and run it with c option to select soundcard , f.i.:
  qasmixer -c 0
• You can also select correct audio device in the view => "show device" box, then save configuration by selecting "from last session" in settings => startup
• Additionnal capture settings by clicking the mic button in the bottom right
