Hello wdmaudiodev people
In Windows' Sound Control Panel, there's a "Configure" button which, when
clicked, shows a screen used to configure speaker arrays. Depending on the
hardware scenario, this speaker layout might be 2-channel, or 5.1 or 7.1
I have some questions on how all this works:
1. For some devices, this Configure button is disabled, for others it's
enabled: what determines the enabled/disabed state of the Configure button?
2. What precisely does Windows do when this Configure button is
clicked? The options in the subsequent "Audio channels" list vary with
hardware so I guess Windows queries data/structures provided/defined by the
hardware device and/or its driver (components) - what/where are these
3. I am studying the MS Sysvad sample to understand this: can someone
please point to the appropriate data/structures in this sample so that I
can experiment and see this audio playback device Configure thing in action?
As much tech detail as possible please!
Thanks in advance.
