Change Audio Playback Device & Change Active Window in cmd

Basically what the title says. I need to be able to:
1. Change the audio playback device to a specific device.
2. Change the active window.

Both need to be able to be done in cmd. How would I be able to do that?

i used this to change audio

Doesn't seem to be working. Doing anything wrong?
I'm typing this in cmd:
"C:\Program Files\nircmd-x64\nircmdc" setdefaultsounddevice "SONY TV *00-C" 1
"C:\Program Files\nircmd-x64\nircmdc" setdefaultsounddevice "SONY TV *00-C" 2

And it doesn't change anything.

EDIT: Nevermind The device was actually: ""SONY TV *00-C". 2 spaces between TV and *. Anyway thanks for helping with that. Now I just need a way to be able to change the active window in cmd.
