|OK, before I get started on this, I have read many other posts / threads / forums on this problem, but none seem to be exactly the same as mine, or have a solution that worked for me.|
So to the problem... well, the title says it all. The problem first made itself known when I tried streaming games using XSplit, and would hear a buzzing sound whenever I turned on a game, which immediately deterred me from streaming.
I am able to cut out this problem by simply muting the microphone to the XSplit software, however this obviously means that I'm unable to stream with voice... in addition to this, if I simply listen to the microphone in the Windows Sound program, I can hear it very clearly, being a bit quieter than my voice but still very audible. I have gone down many avenues with the aim of completely eradicating the problem. With the aid of reading other people's threads with the same problem, I have changed many components of my computer, including the GPU, the PSU and the sound card, to no avail. I have also tried other things such as trying other microphones, plugging the computer into the mains and surge protector / 4-way plugs, and even trying the computer in a completely different room of the house, and none of these have worked.
Recently (maybe within the last couple months) I realised that the sound is directly linked to the amount of load on the CPU, confirming this by going into the power settings and tweaking the "Minimum processor power" setting. With this in mind, I completely took the computer apart, including removing the motherboard from the case, and even the CPU from the motherboard, and cleaned everything from any possible dust before putting it all back together, to eliminate any chance of bad connections... and nope, this didn't fix a thing, other than making the computer run slightly cooler.
So I'm here because I've pretty much run out of ideas, and getting very frustrated because many streamers are able to stream with nice, clear voice audio, whereas I am unable to do so, thanks to this problem.
