Is there an API avaialble to install a ACM Driver

[Das]

I have developed an ACM (Audio Codec Driver) and have two files mydriver.acm
and install.inf

I would like to automate this installtion of this driver rather than using
the Add Hardware option from the control pannel. Does anyone know what API
calls exist to enable me to write a device driver setup program for my
codec?

ACM driver can be installed by just right-clicking on the INF file and
selecting "Install" option.

The following call will do it (copied from the INF file settings):

InstallHinfSection("DefaultInstall", 132, "MY_INF_file.INF");

Create your INF file from this template:

[Version]
Signature = "$Chicago$"
Class = MEDIA
ClassGUID="{4d36e96c-e325-11ce-bfc1-08002be10318}"

I have managed to get the driver to install under windows NT using a
modified version of your inf file, but I noticed there are some extra
registry settings set when using my original inf file and the Add Device
option from the Multimedia option in the control pannel (shown below). do I
need to add these keys? Also is there any extra processing that windows
performs when you use the Add Device option rather than your ini file?
