I have to develop an USB device which will take the sound of th
computer (like a line out) out on windows xp/vista. If you take
standard audio divice (like USB speaker or usb audio converter), yo
have to activate the device as standard sound output to hear something
In this case, your other speakers don't work anymore

Is there any possibility in the USB HID audio profile to do somethin
it will not add a device like a new sound card but only add a speaker o
line out in parallel and you have not to activate it

PS : it has to run without installing a new driver in Windows

HID does not do audio streams. HID can expose audio /controls/ like volume
+/-, mute, etc, but not an actual sound card like device.
