Alter default audio output device from command-line [duplicate]

Question

I have 2 audio output devices:

1. 5.1 Speaker System attached via Toslink
2. Gaming Headset attached via USB

Is there a simple way to change which device is the default output device, from the command-line? I'm interested in scripting it.

Answer 1

Perhaps take a look at the AudioSwitch project, it has also command-line options.

Examples:

1. AudioSwitch.exe -i 1 -- will change 1'th device as default and run AudioSwitch.
2. AudioSwitch.exe -i 0 -x -- will change 0'th device as default and exit.
3. AudioSwitch.exe -l -i 0 -x -- will show device list, set 0'th device as default and exit.
