Select audio devices. For inputs and outputs.

[illume]

As a user I would like to select the sound devices I want to use.

Are we sending output to:

• HDMI
• headphone
• sound card outputs?
• bluetooth speaker

What about input audio?

Currently these are set in main.py with these:

• DEVICENAME_INPUT
• DEVICENAME_OUTPUT

One idea is to select output and input sound devices through the display with the joystick. eg. the home button on the joypad will go to a settings screen, where selecting the kind of output or input is possible.
It would be useful in case you want outs/ins that are different. eg. an audio card input and a bluetooth speaker output.

The audio settings screen could look something like this...
