"intelligent throttling of the CPU" BIOS setting
« on: March 28, 2011, 10:55:26 am »
Hi,

I have a strange audio problem in here.
When playing some video files in WMC the audio crackles.
It does not happen will all video flles,  but it does happen with plenty of them.

In another post, I have found a solution to a similar problem:
http://www.sevenforums.com/sound-audio/31602-audio-crackle-dropping-out-media-centre.html

This user also has a GIGABYTE Mobo, and his suggested solution is to tweak the "intelligent throttling of the CPU" in the bios.
I have a a Gigabyte (GA-EG41MF-S2H), but I cannot find any option to do this in my BIOS. Any ideas?

Thanks!!!!

Dark Mantis

Hi

I would assume he is talking about the EIST function which can be found in the BIOS in the Advanced BIOS Features section.

If that doesn't work the I would advise trying to download  and run dpclatency checker from  http://www.thesycon.de/deu/latency_check.shtml

If you then find that you are getting red bars at all you have a latency problem.

The problem is easilly fixed but finding the culprit can be more troublesome. Latency is caused by bad programming generally. There are various rules for how a program should access the core and if it doesn't follow these rules it can result in the core not being released for the next operation and this causes a bottleneck that backs up. The biggest headache from our perspective is that we have to find the rogue program/driver.

The best way to tackle this is to go to Task Manager and then in the Processes section stop all the processes that are not required for Windows to run. If you do this one at a time until you find the one that is causing the trouble. Then depending on what it is as to how you tackle the repair.

If none of that works you would need to go to Device Manager and disable all the devices not needed to run the system. Then you can enable them one at a time and again see which one causes the problem.

Have fun!

Hi again Dark Mantis,

I disabled EIST . However, this did not solve the problem.

I have also downloaded the latency checker, which did not show any problem at all. I played the files that geneated audio drop outs, and the latency graph was below green colour at all time.

I am a little bit confused with this problem:
VLC plays without drop outs. The problem is only with WMC, which might rule out the possibllity of a device interfering? Also, the same processes should interfere with both VLC and WMC?
The problem only arises in full mode. If WMC is minimised, of if WMC window is resized there is no audio problem at a;;. Only happens in full-mode!!!

Thanks for your help!!!

OK plan "B"  ;D

I think it would be advantageous to have a list of your system hardware next.

I am afraid I have no knowledge whatsoever of your DAC. The fact that it is USB connected rings alarm bells but other than that I can't offer much assistance. Sorry.

Maybe absic might know as he has a lot of experience with digital audio.

No problem, I undestand

The problem is that the DAC works perfectly with VLC... strange problem..

One thing that did cross my mind is have you disabled the onboard sound ?

No, it is enabled, but this should not have any impact, since the DAC is connected to the PC using a USB connection. Thus, the audio data is not rooted through the onboard sound card nor uses the onboard driver.

Cheers!

No I understand that but it might still be worth a try even if it is just to eliminate it as a contributary factor.

 I did disable the onboard sound card from the device manager. No improvement though... :(

Thanks for trying to help
