Hi Xzener,
(Sorry for the slow response; I missed your reply first time around.)
Nope... Unchecking "Adjust Volume While Talking" has no effect on the Volume Control popup.
Hmm -- I tested this on my own system just now and it worked as expected, i.e. no longer popped up the volume requester. Can you confirm that this setting is still off when you restart Media Center?
Also, can you check the settings file "C:\ProgramData\Amulet Devices\Amulet.ini", find the [Talker] section, and see if VolumeAdjust=No?
Finally, can you confirm what version of the Amulet software you are running? (It's displayed on the main Amulet.Settings entry page.)
