Hi guys
I develop a simple sAPO, installation like sysVAD , extension inf and component inf
for now, I wonder install the sAPO on USB headset mic "Jabra UC VOICE 750a MS" for test.
In my develop desktop, usb headset plug-in then seems in-box driver install done.

Can see render that look like has effect APO "Microsoft Audio Home Theater Effects"

but in capture, cant see sub key "fxProperties" exist, no EffectClsid can change for test my APO:
PKEY_FX_StreamEffectClsid = "{D04E05A6-594B-4fb6-A80D-01AF5EED7D1D},5"
PKEY_FX_ModeEffectClsid = "{D04E05A6-594B-4fb6-A80D-01AF5EED7D1D},6"

I check the in-box inf "wdma_usb.inf", sure thing is no match id (USB\VID_0B0E&PID_034C) to inf from device "Jabra UC VOICE 750a"

in my imagination, wdma_usb.inf driver installation that mic and spk are go compatible ID section, but confuse me why only render side has "Microsoft Audio Home Theater Effects" effect?
can any one hint me something!!!?
