Topic: Audio distortion when the simultaneous work of the PC and BabyFace

During the work of the card and while scrolling through WEB pages I hear audible clicks and interrupt the sound clicks correspond to the speed of the scroll.
as I found out the size of the buffer does not affect this. Like any interference or crosstalk, may be the video card. But I thought that a device of such a high class should be protected from such problems. Prompt solutions.

Re: Audio distortion when the simultaneous work of the PC and BabyFace

At the moment when you hear the clicks absolute maximum latency is 1400-1700 ms. In the settings of the RME USB I have a 2000 ms. Please explain what should be the values of the latency in this utility to work properly and what to change to get rid of clicks?

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Utility which I was advised by specialist RME shows that problems should not be. A clicking noise and distortion is.
I think this is a problem that is RME driver.
And here the performance of my machine if the latency I go to installed 2000ms
By Asio Host I put also a large buffer and losses should not be!

Why you can't adequately describe the requirements of his BabyFace to the equipment?
Formally, I can't use the device.
I have a modern computer with Windows 7 on board and there is not the slightest doubt that she was unable to pass on USB 44/16 audio and display the WEB page.

Re: Audio distortion when the simultaneous work of the PC and BabyFace

its all fine here on win7x64.. might want to try to concentrate on one thing at a time.. surfing the web or making music..

good luck=)

p.s. try disabling the acpi in device manager and/or updating your wireless drivers... - best to shut off internet while making music anyway...

Re: Audio distortion when the simultaneous work of the PC and BabyFace

With such success, I could buy another device is much cheaper!
I am disappointed in my purchase and especially the level of technical support. Where I just advise and without the new computer exchanged for something, which PROBABLY will work.

Re: Audio distortion when the simultaneous work of the PC and BabyFace

There is no known driver problem. Issues like this are not caused by the audio interface. Clearly, graphics activity on your system is causing interruptions in audio playback. Please look through the link list with advice on system tuning. Also try increasing buffer size in the settings dialog and decreasing colour depth of the display.
Please understand that optimizing your computer's performance is not the primary task of our technical support. We can give advice, but you will need to work on this as well...
If you want a computer that will not need such tweaking, consider buying from a dedicated supplier of audio computers.

You should find the source of the issues, but if you are a Firefox user then a possible workaround would be to disable "Hardware Acceleration" in FF' settings.

I did not set the task to optimize my system.
I want to device RME worked as it should work. if there are requirements to the equipment of why this requirement does not announced?
I have a modern system without any specific features. And I shouldn't do the tuning of your operating system,because all of the other devices in my system is running fine. let me please tests or any of the tools explain such behavior of the card.

You have not told us anything about your system.

The requirement for high latency audio is a computer that works, the requirement for low latency audio is a computer that works *perfectly*.

The requirement for driving on the street is a car that drives, the requirement for driving in the Formula 1 is a car that drives *perfectly*.

I have a modern system without any specific features. And I shouldn't do the tuning of your operating system,because all of the other devices in my system is running fine.

I have a modern Nissan Micra without any specific features. And I shouldn't do the tuning of your engine when I want to drives races, because I can drive on all streets and all the other devices in my system is running fine (blinker, wiper, tires). fryingpan wink

let me please tests or any of the tools explain such behavior of the card.

First you need to find out which of your hardware (drivers) is causing the issues. Most often this is Wlan, USB card-readers or graphic-card. You can either disable those one by one (replace the graphic-card driver with the "Microsoft Standard VGA driver" to find out, NVidia drivers are known for these issues) or try the following software to get an idea of what could be the source.

I understand if this seems like too much hassle for you as an end-user, so I advice to get help from a professional to setup your system or just buy your system from a dedicated Audio PC builder (there are reasons why these exist).

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Not talking complete nonsense!
I bought the device that is connected to the system. And the system complies with the requirements of the manufacturer. I buy the device serial production, which should work in the medium statistical setup.

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Your system does not comply to the requirements of Microsoft Windows. Each single device driver should not create DPC latencies higher than 120 us (Microsoft's own drivers often fail to do that, too, though). At least one of your drivers does not work like it should, most likely the NVidia graphic-driver. See those yellow bars on DPC latency checker, these need to be turned to green in order to use low latency audio.

Maybe your USB port is misbehaving or your BIOS?

These are the issues you have to deal with when buying an off-the-shelf computer and doing the setup without professional help. There are myriads of PC configurations out there, numbers on paper don't tell much about how your system works in practice. That's the reason why so many musicians either buy Macs (very limited combinations of hardware and "closed" system) or ask a dedicated Audio PC builder.

No one is blaming you for trying a less expensive path, but you are pointing fingers at the wrong direction when you try to blame the Babyface for your PC's shortcomings.

And you have been given several advices already on how to narrow down the source of your problems. Please follow these and report back so that we can help you get better performance out of your system.

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Don't misunderstand me. I want a new device I bought worked fine. I think RME has developed an external USB device just wants to replenish its ranks among non-professional computer geniuses, and ordinary consumers. Why should I think about latency system drivers? Being a simple musician.

USB Ports in BIOS marked as HiSpeed 480mbit

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Let me add that Timur has hit the nail on the head here. I couldn't have said it any better. Please reconsider your position.

Mind that this is not an issue the Babyface "not working". The BF is the victim of the computer's performance issues, not the cause. The fact that the audible symptoms show up on the BF's outputs do not mean that the BF causes them. Also, the fact that other devices "work perfectly" does not mean much. Requirements for uninterrupted audio are quite different to other hardware you may be referring to.

As outlined here, the cause of the problem may be the ICH7 to a degree. This system does not seem to be all that new. What kind of CPU is this exactly, a Dual Core as outlined in the system requirements?

If you are unable to find the cause, finding professional help is certainly recommended.

Speaking of Nissan... They will sell you a car, but you need to take (and pay for) driving lessons yourself... The car doesn't "just work" because you bought it and it meets the roads' requirements, sorry.

Interesting ICH7, specified as part of one of tested systems on your list! (Asus A8JP)

RME advised me to do a test, I spent. The results in the picture above judging by the inscription in the problems should not be. And moreover if the device is so demanding on the computer. You are obliged to inform the consumer! and give back to buying the possibility to check the compatibility!

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Listen audios, if you want a computer to play a computer game, no the computer is not set up from the factory for high-performance needed for a video game. It may take a new graphic card, new fast connection to the Internet if played on-line, and other performance enhancing techniques that are allowed and can be set on the computer. You have to know the Operating System and find out where to change the settings to do that - to play a game.

Now, music and recording music on a computer is no different. You have to set up the computer to make it happen. Or else take it in, and have a computer technician set it up. That is the way they sell all computers - as general purpose running computers, but the computer can be tweaked to make it better either for computer games or recording music. If you want to do Word Documents, that is what your computer is originally set up for. All computers are the same when bought.

You have a yellow bar going up in the picture that is the wrong part. It was mentioned what it could be, you have to find out what it is. I have an older computer (Pentinum 4) and the Babyface works great with it, but my computer is set up for Performance and High Performance, not general purpose computing.

Just go to a recording studio and record your music then and pay for it, it is obvious you think you can just crab about what you are doing wrong, and everyone should follow your crap. No, we will not, and definitely I will not, even if they do here at RME.

My Babyface is great and it works great with my old computer, and it will even work better with a new computer, but then I would need a new computer for plug-ins that would use more computer CPU power to work, and I know that, so I don't use them, or I will use less of them, and know that the computer can only handle so much, and a newer computer then would be needed to use more plug-ins or record more tracks (and so far I can record as many tracks as I need and the Babyface works great and fine with anything I am doing).

Get off of the attitude because it is in your computer, and go find out on the Internet how to tweak your computer to record music. It is done doing a search for it perhaps in Google or some search engine. Get busy or else the Babyface can not work with your crappy computer because it is right now your computer, but your settings can be changed to make it better.

Do your homework, and quit acting like a 16-year old kid that is stupid!

Re: Audio distortion when the simultaneous work of the PC and BabyFace

ICH 7 should be ok, but it does show the system is a few years old already - is this a Core 2 Duo or similar?

Nonetheless, plain numbers alone do not guarantee a well-tuned system. It is the computer that has to work with the audio interface and software, not the other way round.

Re: Audio distortion when the simultaneous work of the PC and BabyFace

Hi,
No computer be it an off the shelf Dell or HP, Apple or DIY is configured for optimally for Pro Audio. Any one using a computer for Pro Audio, Pro Video, Gaming or Desktop Publishing has to at some point alter a setting with either the Operating System or with a computer hardware setting in order to get the best performance out of it. Pro Audio especially requires optimal High performance settings because of it's near real time data streaming requirements.
The typical computer by default is configured for low power consumption. it does this this by constantly the clock speed of the CPU as well as altering the power use or even turning devices on and off when it thinks they need to be. All of these have a very negative impact on the real time performance a pro Audio device needs. These power management issues effect all Pro Audio interfaces to some degree or another. You could be using a $99 M-Audio Audiophile 2496 a $750 RME Babyface and anything in between or above and you will still have the potential for the issues you are having. You machine is no different than anybody else's in that it needs to be optimized for use with a Pro Audio interface.

As others have mentioned you need to find which device or devices are causing DPC latency that is high enough to effect Pro Audio interfaces.
Th first and easiest thing to do is optimize Windows for Pro Audio. If things still aren't improved then you can start troubleshooting your system on the hardware level. The odds are that even if you end up getting a Pro Audio interface other than RME these same issues to some degree will still exist.

Here is the best place for optimizing Windows for high performance no matter it be Pro Audio, Pro Video , Gaming, etc.
