  1. Hi guys... I'm on the verge of throwing equipment through a wall. I keep thinking I've fixed this problem and then it comes back. I don't know where else to turn and this is 3 weeks in the making now. If someone can help me with this, I will send you some money via paypal... If it can't be figured out over the forum board, then if someone in LA is a real specialist with this sort of thing, I can pay you to come out. I just don't know what else to do anymore... I have a brand new computer. Fresh Win 7 64 install from cyber computers. I mention that so you know there isn't any pre-installed software on there. It's pretty powerful... i7 3820 with 8gb of RAM and a solid state drive for the OS and software. Asus Sabertooth X79 motherboard. Hooked up via USB is a Behringer Xenyx X1222USB mixer. Everything seems great until I turn on a webcam. The C920 is hooked up to a USB3 port. The second I turn it on and put it in 720p or higher, I usually start hearing pops. I've gone hours with it being fine. That's one of the frustrating things. Today it is not fine and every single time I get things going these pops happen. I made an audacity recording while the popping was happening. Unfortunately it's not what it sounds like. There are pops you can't hear on here, but a pop in my headphones is really a pause in the recording I believe. Anyway, You can hear it at http://www.comedybone.com/images/clicking.mp3 (It doesn't sound exactly the same because it seems like each click actually pauses the recording.) Hard to explain but it is pretty similar in the recording. What I've done so far... • At first I was told it was because I had 3 of these C920 cams on one USB bus. Not really the case, but I bought 3 USB3 PCIe cards and installed them. They work great and this still happens. I have discovered that it happens even when one of these cams is producing an image. Usually at 720p or higher. • Today I grabbed my cheaper webcam (Logitech 600) and put it on there. It caused the popping sound too. Not as often, but it did in 720p mode. Even when it was the only cam hooked up. The second the picture shows in hd it does this. • I BELIEVE this only happening when the mixer is hooked up by the way. Maybe there's a conflict between logitech cams and this mixer? The Behringer driver is installed. • I've disabled the on board sound since I want to use the Behringer for recording and hearing everything. I've disabled the webcam mics... • I've noticed that in the device manager there is an AMD sound driver, and realtek sound driver and the behringer. I've disabled the other 2 at times and this still happens. Not really sure why there's AMD and Realtek. • This popping happens in the logitech "quick capture" software in photo mode, not video... Or in XSplit Broadcaster. Which I'm going to use for streaming the video to our podcast online while we record. But it starts happening as soon as any software shows a picture from the cam at 720p or higher. It's capable of doing 1080p. • In the task manager, nothing is making the CPU overload. Never even gets to 20% while things are going on. The weird part is, I have had all 3 cams streaming on the net while simultaneously recording the video and audio from the mixer to my hard drive with NO PROBLEMS... Sometimes I turn the computer on and just pulling up the video starts this popping on the other hand. I'm not playing with settings. I don't know what is causing this. If anyone has any ideas I'd be most grateful. If you have any questions regarding anything in my setup, I'll get the answers for you very quickly. I'm on my computer all the time. I'm starting this podcast in 2 weeks, as you can see on the site where that mp3 file is hosted. I have to figure this out. It's all new equipment... Mixer, computer, cams... So frustrating. Was thinking about going out and buying a microsoft webcam tomorrow to see if it's a logitech thing, but not hopeful since 2 different logitechs made this happen. I can grab screen captures or tell you any settings that might help figure this out. Or I live in the San Fernando Valley if any specialists are in the 818. Thanks a lot B
