Installed alsa-utils when amixer was missing using this command sudo apt-get alsa-utils

Currently on using command amixer controls this is the output

numid=3, iface-MIXER, name='Master Playback Volume' 
numid=2,iface-MIXER, name='Capture Switch'
numid=1, iface-MIXER, name='Capture Volume'

Various drivers exports vairious controls. Also, it appears that your system is set to communication with a sound daemon by default (pulseaudio or pipewire). Try add option -c 0 or -D hw:0 to communicate directly with the hardware driver.
