PCI-424 driver prevents Windows from going to sleep

[motucitizen]

Hello,

I have a 24 I/O with a PCI-242 card. Whenever I try to put Windows to sleep with the PCI-424 driver installed, Windows does not sleep, and about 30 seconds later, the following message appears:

"System Standby Failed: The deivce driver for the 'MOTU PCI Audio Device' device is preventing the machine from entering standby. Please close all applications and try again. If the problem persists, you may need to update this driver."

I have no applications running. I have the latest driver installed.

I also tried enabling hiberation (to try that as an alternative to standby). I get a similar message:

"System Hibernation Failed: The deivce driver for the 'MOTU PCI Audio Device' device is preventing the machine from entering hibernation. Please close all applications and try again. If the problem persists, you may need to update this driver."

So, if I want to avoid leaving my computer fully-powered all the time, then I am forced to shut down when I'm not using it. This is inconvenient; I'd rather just use the suspend/resume feature like a normal person.

Anyone else run into this?

Thanks,
- Matt

Hi Matt,

I did run in to this in the beginning. It turned out to be the ASUS ATK utility. I updated the driver for this, and it worked flawlessly after that.

I got a question for ya: Ialso own a 24io but get terrible performance issues with the ASIO driver. Pops crackles and distortion are all over the place when I set my buffer to 1024 or lower. Do you have similar issues?

Hmm... I don't have the ASUS ATK utility. What is it?

When I remove the MOTU driver, then my system can sleep/hibernate normally. When I install again, the problem returns. Besides, the message identifies the MOTU driver specifically... so I'm not convinced the problem is due to another piece of software in my case.

So, you can sleep/hibernate with the MOTU driver installed? You said that you saw this problem "at first" -- did you get the same message as I did, identifying the MOTU driver?

Sorry, I don't have any specific advice for your audio glitching problems. I have been able to use the ASIO driver down to 512 sample buffers without glitches. Usually, glitches mean that the audio buffers are being starved... and this is simply a function of how efficient the software is and/or how fast your machine is. If the glitches go away when you increase the buffer size, then is more evidence that your software/machine combo simply can't keep up with smaller buffers.

Thanks,
- Matt

Matt, what are your system specs?
