I think it has something to do with malfunction of combined Line/Mic In / S/PDIF Out. The sound card is 2 slots away from GPU and on PCI vs PCI-E.
Not sure what you mean by 2, but my PC is powered through the grounded surge protector, I feel no electricity on PC body either 3. The microphone is connected straight to the sound card 2. The strange thing is: it somehow goes away if you blow strongly into the microphone a few times!ġ. It's not constant, it happens randomly and from what I remember I can't fix it by restarting the sound card in Device Manager. It's almost like this loud white noise issue, but for microphone. So my problem is that people hear nothing from my microphone except those loud noises (especially with microphone gain =)) ). I was using 1.75a r2 with my Xonar D1 on Win 7 SP1 圆4 for a long time and I never had this problem until this year, no other changes was made either. Not sure if the article title has something to do with its contents, at least for my problem. If none of these work your only option would be to go with an external audio card or DAC or use the S/PDIF audio output if you have a receiver or speakers that have S/PDIF input.Įrm. For microphone buzzing, you could try connecting to the onboard cards microphone input if you have a dedicated sound card and use its microphone input.You can find noise isolators that you connect to the sound card analog output but I won't recommend these as they might lower the sound quality ( #1, #2).
You can also try this in conjunction with slightly lowering the clocks and or the Power Limit.
For AMD Radeon cards I recommend you use MSI Afterburner and offset negatively the voltage by as much as possible.You can also try this in conjunction with slightly lowering the clocks and/or the Power Limit. Especially if the noises are caused when the video card is in use, undervolt the video card:.If you care about esthetics you can do something like this, but first make sure it works with the aluminum sheet. Make an EMI shield for your sound card ( #1, #2).Move the sound card farther away from the GPU.The problem might be from too much EMI (Electromagnetic interference):.If the connection to the ground works properly, you will not feel any current when touching and moving your fingers on the metal parts of your PC case. Connect your PC to a grounded electric outlet.If the issue is resolved and you still want to use the front panel connection read this ( ). If you are using the case front panel connection then try connecting the speaker system, headphones, or microphone directly to the card.If you have hissing, buzzing or crackling noises coming from the speakers or headphones or if people you talk to using the microphone complain that they hear buzzing noises coming from your end, you could try the following solutions to solve this:
