Using amixer to reduce right speaker volume to zero(and leave left unchanged)

alsa-project/alsa-utils issue #269 was opened from sierret:

I'm trying to right a script to reduce my right speaker volume to 0. I know the code:

`amixer -D pulse sset Master -,0`

sets the LEFT speaker to zero and leaves the right unchanged. However, for the life of me I can't manage to modify this code to do the opposite. And there don't seem to be adequate resources directing how to do so floating around the interwebs.
