I want to develop an Audio Mixer control applet similar to sndvol32.exe that
Windows XP exposes for my USB Audio device. The device will use the generic
USB audio driver provided by Windows so the idea is to create a GUI for some
advanced settings controlled by standard USB Audio Class 1.0. For example,
my device supports equalizer building block of a feature unit and I would
like to control it via this GUI. I have noticed that USB Audio driver on
Win7 sends the requests for Equalizer but there is no GUI allowing to
control it in Win7 mixer.

Is this possible? Which Windows APIs should I look into? Are there any
examples with similar functionality available? Would it be possible to
register such application so it is loaded instead of sndvol32.exe or the
equivalent on the later OS'?


Thanks in advance for the answers.
