yep,first of all i do use a creative tactic recon 3d alpha headset. my drivers up to date and its working very well in windows recorder, teamspeak , any other in game voice chat etc. yes i know i ve to push and hold the button to talk in game.
problem : the capture value is very very very low even the threshold is %100 in game and windows both. i really need to shout like a maniac to make game detect my voice. i searched around a lot and havent manage to find a solution. there s also no .cfg file to play with on steam. anyway developers please you need to look on this issue seriously and asap. or if you have a fix, please share.
This might be due to whatever settings you have enabled for your sound drivers. Sometimes checking "Microphone Boost" is necessary.
Can you show us DxDiag info for your PC, please?
