Hello. I am beginner user of kX Project. My system is Windows 7 64bit, and my sound card is SB Live 5.1 SB0060 10k1. Drivers working great with standard SDP settings but i have one problem, meybe its a known issue but im not sure. I have plugged two stereo speakers to black output, and two speakers to green output (i am using rear=front to have sound from both outputs at the same time). When i set 4.0 rear=front (surround:copy) in Surrounder+ i have "echo" effect related to volume. When i opened Peak i found something strange.. the volume in left and right speaker is different. One speaker is louder -3db ..on both outputs. When i disable rear=front the problem doesnt exist anymore but i have only black output working... Also disable "Stereo Chorus" in SDP helping fix this issue and i can again use rear=front. After disable Stereo Chorus the sound is perfect clear and all speakers have the same volume. Does this mean Stereo Chorus plugin causing this ?? This is known issue ?? What is most interesting "echo" sometimes just disappear without disable Chorus but after pc restart problem is back. Sorry for my very bad english.. Let me explain again. With settings 4.0 rear=front i have "echo" and one speaker in both outputs is louder. When i disable Stereo Chorus OR just disable rear=front and set standard 2.0/5.1 Direct Path the problem is gone and speakers have balanced volume and play equally. Latest alpha 3551 doesn't solved the problem.
