requires pacmd and xdotool. I use it assigning a shortcut key in i3wm

I'm trying to modify this to behave intelligently with chrome windows (same PPID, different sinks). This isn't working well because xdotool getwindowpid returns the same pid for all chrome windows, regardless of which one is focused. If multiple chrome windows are currently playing, then things go south.

I added a PPID check and now it does work for chrome, but it can only switch the first window it finds.

If I remove the break at the end, I can at least cycle all chrome windows with one button-press.

Any suggestions?
