It is caused by the increase/decrease in power consuption, as in general the audio chip isn't properly isolated from the power source of your computer. So, as more power is used (by slightly increasing the CPU speed, for example, to render the page as you scrooled it), the audio chip amplifies it.
It is a problem of some motherboards, and one way to get ride of it is to use another audio chip (for example, a small USB device that acts like a sound card).
- fipple 8y agoThe external USB sound card doesn’t always work because the USB supply voltage can vary with processor CPU. You need to use a USB headphone output with good isolation.
- stan_rogers 8y ago...which is still a "USB sound card", no matter how you choose to look at it. It still needs to be a combined DAC and headphone amplifier in addition to being a set of 'phones. Personally, I use an Audioquest Dragonfly USB DAC/headphone amp, which gives me the option to use either headphones (of my choosing) or speakers. (And unlike a larger "breakout box" USB sound card, it's quite portable, being about the same size and shape as USB thumb drives used to be.) It's a good fit for me, but if you need mic input, there are other devices - or you can still use the mic in of your regular sound card/integrated audio.
