4: Audio device
The name of the audio device in use.
5: Volume
A control to set the output volume. This is not supported by all output audio devices.
6: Channel Map
This controls how the left and right audio channels map on to the IQ channels.
- I=L, Q=R - The left audio channel is driven to the I channel. The right audio channel is driven to the Q channel for a complex (analytic signal)input.
