Hello,
I noticed a very high pitched hiss going through my speakers and headphones that is driving me crazy, I can't figure out wheter it's coming from my pc or my dac (or something else?!)
So first of all, here's my setup :
MSI Z170a gaming pro carbon mobo -> mackie big knob studio+ interface -> speakers/headphones
So I made some measurements with my phone mic and it is cleary visible.
Here's the graph where you can see the spikes at around 8 and 13khz coming from my pc.
So I then tried using another computer (my laptop) and came up with these results:
The spikes are still there but there are more of them at different frequencies.
Some considerations :
- Changing windows sound level does not affect the noise
- When no sound is playing the noise will stop after some time
- Using a 3.5mm jack coming from built-in soundcard to the stereo input of the interface makes the noise disappear
Any help would be greatly appreciated
