This assumes stereo output. You still need to ensure a single value in the case of multiple left speakers:

amixer -D pulse sget Master | awk -F '[^0-9]+' '/Left:/{print $3}' | head -n 1

Yet another incorrect use of awk. It can also take the place of head:

amixer -D pulse sget Master | awk -F '[^0-9]+' '/Left:/ { print $3; quit }'
