class VirtualAudioDevice
Defined at line 37 of file ../../src/media/audio/drivers/virtual-audio-legacy/virtual-audio-device.h
Controller for a `VirtualAudioDriver`.
Each instance of this class represents two objects:
1. A virtual audio device in the device tree, represented by a `VirtualAudioDriver` object.
This device appears under `/dev/class/audio-{input,output}`, `/dev/class/dai`, or
`/dev/class/codec`.
2. A FIDL channel (`fuchsia.virtualaudio.Device`) which controls and monitors the device.
The device lives until the controlling FIDL channel is closed or the device host process decides
to remove the `VirtualAudioDriver`.
