Mic Input Device assumes first channel only

[towneh]

Describe the bug?

When presented with a Digital Interface for Mic input, such as those used with condenser micrphones, it is possible to connect a microphone to channel 1 or channel 2, which is presented to the OS as a stereo channel input device.

Basis currently assumes that the Microphone device is always a single channel Input device, so Microphones connected to the second input do not transmit any audio.

Steps to Reproduce

1. Select a Digital Interface input device for the Microphone Input in Basis.
2. Plug the microphonee in to the second MIC IN on the Digital Interface.
3. Attempt to talk and no one will hear you.

The expected behavior

Basis could either:

1. If possible, downmix all inputs to a single channel (this may have the added advantage of allowing someone who is playing an instrument with Line IN and a separate microphone through the Digital Interface to cleanly transmit their sound in-game)
   or
2. Spawn a sub-menu when encountering an Input device with multiple channels, so you can specify which channel to broadcast.
   or
3. Warn the user that their device is Stereo or Multi-channel through the UI.
