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!!!!

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!

Thanks Dark Mantis,
I will follow your recommendations!
Cheers

You are welcome and if you still have any problem please just post back.

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..
cheers
-
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

Have you tried to ask GGTS for help ?
Just enter your email address and click on the language of choice.

no. I have not but it is a good idea!
Thanks

May I suggest to use the onboard sound card, to see if the problem is there... if it is.. than it's simple codec problem.
Can you please try Windows Media Player?
Also what Windows are you using?
Did you check if your USB sound card have the latest drivers? If so, can you try old drivers. Be sure to uninstall the old one first, restart your computer and install the other drivers.. do not upgrade a driver.

Hi Goodbytes,
Thanks for your reply,
IMay I suggest to use the onboard sound card, to see if the problem is there... if it is.. than it's simple codec problem.
I did it, and the problem dissapears but I have noticed something else; both onboard sound card and DAC are rooted to an AMP:
-onboard sound card to input 1 of the AMP
-DAC to input2.
IF onboard sound card is selected as default sound card, there should be no sound in input 2 in the DAC. However,the noise (sparky crakle sounds) is still present, which shows that somehow a buffer is getting full of digital noise there . It is difficult to understand the reason why that only happens in full screen mode in WMC...
Can you please try Windows Media Player?
I did it, and the problem is also gone. If VLC is used there is no problem at all either. It is only WMC in full mode screen
Also what Windows are you using?
Windows 7 32 bit
Did you check if your USB sound card have the latest drivers? If so, can you try old drivers. Be sure to uninstall the old one first, restart your computer and install the other drivers.. do not upgrade a driver.
The DAC does not have its own drivers. It uses the generic USB DAC driver provided by Windows7
Thanks a lot!
