These effects used to be much worse in the nineties, often even if you had a fancy sound card. Electrical noise is significantly reduced now.

Majority of sound cards up to late nineties used dual layer PCBs with terrible grounding strategies so even the ones bothering to condition power for analog section still audibly picked up interrupts, DMA transfers and CPU load.

> I am working on an isometric game inspired from Gnomoria, RimWorld, Dwarf Fortress, etc.

That sounds interesting. Could you elaborate further?

Still a very common problem today and (aside from the need for more output channels or the need for professional mic preamps) the main reason people get USB audio interfaces.

As for USB audio interfaces I really love what RME is doing with their TotalMix, but if you want bang for the buck Behringers UMC series is the place to be.

I am a bit confused. Based on the earlier paragraphs, it hinted that the solution would be related to the frequency of the job, not necessarily its load (since other games do not have this issue), but then the fix was not changing the frequency but the load of the job.

What am I missing?

There's a certain cinematic quality to this story... perhaps so much so that if it were to be included in an actual movie it would be seen as "too over the top" (i.e. CSI-like)

anyone else get big audio buzz relief using the extra, three prong cable on their normally two prong apple laptop charger? it felt as good as having my wisdom teeth out after i switched

Two prong apple charger is mind boggling to me. I can feel 50Hz static when gently touching the laptop. Problem goes away when grounded properly.

Also surprised there are barely any three prong hot plug adapters for the original charger.

And the internet if full of complaints on this matter: https://www.reddit.com/r/macbookpro/comments/1lfu1by/tinglin...

Happy to hear I'm not the only one with this problem!

Oddly I can't access the site. The URL is 301-redirecting to itself in an infinite loop (which the browser finally stops and shows an error page).

I have this weird thing whenever I have headphones and open the Dota2 settings on my Mac, then I not only get buzzing but the overall sound quality plummets!

Bluetooth headphones? the settings menu could be using the microphone somehow and switching to mono audio because bluetooth is low bandwidth

Oh yeah, Bluetooth headphones, I think this might actually explain it.
