'''
This test is for checking playback-routing of devices based on Echo Fireworks.
Only two devices support this function, AudioFire2 and AudioFire4.
AudioFire2:
Playback stream ch1/2, 3/4, 5/6 can be assigned to analog out ch1/2,
headphone out ch1/2, and digital out ch1/2.
AudioFire4:
Playback stream ch1/2, 3/4, 5/6 can be assigned to analog out ch1/2,
3/4 and digital out ch1/2.
Usage:
To set routing, give two arguments below.
Hardware port id as a first argument.
id AudioFire2 AudioFire4
0 Analog out ch1/2 Analog out ch1/2
1 Headphone out ch1/2 Analog out ch4/4
2 Digital out ch1/2 Digital out ch1/2
Playback stream id as a second argument
0 Stream out ch1/2
1 Stream out ch3/4
2 Stream out ch5/6 (shown as digital out)
Give no arguments, current state is printed.
