I currently have two computers connected to a KVM. One of the computers is connected to a spare display. Both computers are connected to an audio mixer. The KVM has DVI for video, and USB for the keyboard/mouse.
Anyway, sometimes I will start up a movie/video on the computer with the spare display, and put the window on the spare display, and then with the KVM switch to the other computer. Once I switch to the other computer Windows decreases all the audio volume for some reason, so the video which was playing great is barely audible.
Is there any way to disable this behavior, so I can have a video running on one computer, and be playing a game, or doing something else on the other?
The behavior seems to have nothing to do with the model of KVM attached since I have seen the behavior on 3 different KVMs, but since all the comments I have have gotten so far bring that up, I have included links to the models below. To repeat, I am NOT using the KVM audio ports, I have the audio from the computers directly routing into a mixer.
The audio does not return to the levels when I have reselected the computer. Here are some captures of the mixer before and after the switch. After a KVM switch I have to manually adjust the Windows mixer settings to get audio back to the normal level.

Ok, I have an update with an additional fact, but I really don't understand why it should be making a difference. The audio output from the on-board audio device in my computer is connected the mixer. Additionally, I have the USB audio adapter that comes with a logitech USB headset. I have a microphone connected to the adapter. So if I disconnect that adapter the audio levels do not change when I use the KVM to switch between computers. With that adapter connected, when I switch between computers the audio to the speakers drops to nearly 0, but not quite.
