Wasapi gives cracks


#1

Hey guys, I noticed on my new computer the WASAPI driver gives cracks on many different buffer size settings.
It’s now on Shared mode - 640 buffer and still now and then a small crack.
I never got this before on other computers.
In wasapi 48Khz - 256 and up it seems much much better but not 100% gone…
I lately installed Process Hacker (and inunstalled by now, back on Process Lasso), could this have had some influence?
Can I reset the wasapi drivers?


#2

Why not use ASIO instead?


#3

I am wondering how you are setting the buffers in WASAPI? Does Cantabile give you that possibility? (Obviously never tried it!)

I use asio on stage with my soundcard. I use wasapi on my desk for programming.

Yes wasapi has also buffer settings.


#5

Does the Profiler show anything suspicious?


#6

Could it be that your audio chip works at 48 kHz natively and 44.1 is converted via software?


#7

The profiler stays low and so does the CPU.
Strange. It even happens with synth1.

Good thinking about the chip. When i set to 44.1 it gives an error. And on 48 it works better.
It’s a 9th gen i7


#8

This is strange, other people have also cracks with synth1. I haven’t been updating my system. So it’s a mystery.


#9

Think I’ve found the guilty one. :wink:
Process lasso switched to idle mode after several second. Does switched power plans.
Also still troubling with k meter. I love the plugin, there’s no better for now, but CPU spikes up to 18%
Update: 48%
update: 117%
Update: 6761% :thinking::astonished::astonished:

Wow, that’s a massive stall. The question is: is it the plugin or something about your system?

Try reproducing it a couple of times and see if it’s always in that plugin.


#11

The clicks are gone but k meter is still there. I don’t think it influences the audio?
Although if my CPU needs stuff and this is also happening it will glitch.
I contacted the dev.

But haven’t seen it before so i think it’s this plugin.
I’ll put on the profiler more.

hm, not completely gone on wasapi, so strange… I keep on digging…
Strangely enough:
When switching from Wasapi shared mode to 48Khz mode the CPU use is higher. But less spikes. Probably because Battery or others are doing a conversion?
Resonse seems faster…
Good tip @Torsten
