I have a problem (and I have had this for some time). There are new interesting things in the new sound mixer stack in Vista, but it is also reinventing the wheel. Since then, many applications that used Volume Mixer on a Windows system to mix different voiced outputs into a single input (e.g. Wave-out + Line-in → Stereo Mix) have stopped working. The main example of this behavior is the Shoutcast DSP plugin (it can be useful for testing solutions).
How can I turn on the XP-mixer controls again, or perhaps somehow reproduce this behavior so that the program (SC DSP) can correctly control the microphone / line input playback volume along with the Wave-out playback volume?
My thinking was to emulate a program connected to Vista Mixer for Wave-Out and Line-out (or microphone speaker volume — all playback shown as separate custom “programs” so that Vista Mixer can refer to it) and “connect "it’s to the system under some emulation, which is the old volume mixer control interface for the program, but I frankly don’t know how to do it.
To clarify: this is not my computer (this is an HP Pavilion laptop). The problem seems to exist mainly due to the fact that the Vista mixer controls individual programs, rather than separate inputs / outputs. The hardware is fully capable of doing what is needed when using Windows XP. I am well aware that this is a problem with the driver, but the driver is simply prepared for what Vista introduces the programmer through interfaces. The mixer device — as can be seen from the operating system, but may appear in the software — is based on the mixer APIs for controlling the Windows audio system.
