High AudioDG.exe CPU usage: Bit depth? - Page 2

post #11 of 29
It's definitely an improvement, but still far higher than what I see on my Realtek onboard solutions or any of my C-Media based soundcards. These are all pretty much stuck at zero all the time, occasionally spiking to 1% if I'm doing multiple audio tasks simultaneously. Overall utilization is so slow that I only seen about a dozen seconds of CPU time total on a system that's been running for a month straight without restarting.

It's been a while since I've made a serious attempt to use a Creative part (I pretty much gave up on the company after the original Audigy about twelve years ago). So, I cannot say for certain what is typical for your card, all I know is that I have not seen such high audiodg.exe usage since audiodg.exe became a Windows component. However, I'm sure I've got an X-Fi laying around somewhere, so I'll check on one of my other systems when I get a chance.

Microphone is analogue or USB?

My audiodg doesn't even hit 1% usage in games, I just checked.

I'm gonna uninstall everything Creative and take the card out of the system. Then, I will compare it against my on-board one...

Analog, ofc, it's plugged to the X-Fi. And USB mic doesn't have any audiodg issues, as I just tried.

Yeah, I'm about to sell the card, after this. I don't want to hear about Creative ever again... not even PAX drivers (desperate attempt lol) fixed this.

Running the Realtek ALC898 that my motherboard has integrated. Tried, just for the sake of it, 24 bit at 192k in both microphone and speakers, playing, with the Skype echo-test while listening to itunes in background. Audiodg was in decimals (0,x cpu usage), reaching 1,2% for a fraction of a second. It does not reach 0,4% on 96k.

I think I'm done with Creative for a while...

I can guess the ALC898 is inferior to an X-Fi in terms of sound quality (but by how much?), yet, well. At least, it works as it should.

Going to depend on the specific implementation/motherboard.

You'll have to test it yourself to see if there are any perceptible differences.

ALC898 is a decent chip, it's the support circuitry on your particular flavor of motherboard that's going to make or break it. The reason a discreet sound card usually sounds better has little to do with the Codec/DAC/ADC on it and more to do with the quality of the capacitors, op-amp, and voltage regulation on the board.

Personally, I've had a Xonar DX, Creative SB ZX, and compared to my on-board ALC898 on P9X79 WS, I can't hear a difference. Now, I CAN hear a difference on my Focusrite Forte (external USB DAC, $400+) - but it's subtle.

Something to consider, Microphone might be driving CPU utilization up if you have any kind of noise cancellation algorithm option enabled AND have the "Listen to this device" checked in your Microphone Properties dialog box in Windows. "Listen" should always be unchecked unless you're using the mic input as a line-in.

Thanks a lot for the explanation on onboard sound smile.gif

Regarding the microphone, it happens to did the cpu mad with and without nose cancelation, with and without listening. Simply switching to "recording" tab in the sound panel already puts the cpu at 15%+

This might sound like a stupid question -- but what CPU do you have? Could be that the stress of recording (or just monitoring) the 24/96 signal is really worth 15% CPU overhead. We're talking a steads 6 bytes * 96000 samples per second for stereo, that might be enough to make an older CPU like a Pentium D or Celeron hit 15%.

A 4,7Ghz 3570K, sadly.

Sadly as well, the Realtek card wasn't able to output a decent volume on my headset, so I had to go back to the Creative card... for now, the CPU usage seems to be around 4% if after installing I don't even open the Speakers options. Let's hope it stays like that.
post #20 of 29
That's ridiculous for a dedicated hardware sound card. Four percent of an overclocked 3570K? What would that thing do on something like an HTPC or a budget box based on a Sempron?

I'm sure Creative would argue that it doesn't matter how inefficient the drivers are, since modern CPU's are so powerful, but that doesn't really justify it. I just monitored AudioDG on my computer for quite a while (Xonar DG, UNi drivers), and it never even hit one percent.

I think I'd flip that card and get something from a company that actually knows how to write a driver. I moved away from Creative about a dozen years ago, and this doesn't inspire me to ever give them a second chance.
