Change volume on different soundcard

Added the following lines to .config/i3/config:

bindsym Mod1+r exec amixer -c 1 set PCM 5%+ && amixer get Master -D pulse | egrep -o '([0-9]+)%' | egrep -o '[0-9]+' | xargs -0 volnoti-show
bindsym Mod1+c exec amixer -c 1 set PCM 5%- && amixer get Master -D pulse | egrep -o '([0-9]+)%' | egrep -o '[0-9]+' | xargs -0 volnoti-show

bindsym Mod1+Shift+r exec amixer set Master 5%+ && amixer get Master -D pulse | egrep -o '([0-9]+)%' | egrep -o '[0-9]+' | xargs -0 volnoti-show
bindsym Mod1+Shift+c exec amixer set Master 5%- && amixer get Master -D pulse | egrep -o '([0-9]+)%' | egrep -o '[0-9]+' | xargs -0 volnoti-show

Now there are two shortcuts for two volumes :)

Use vim to change encoding of file

:set fileencoding=utf8, then :w newfilename.
