a lil issue

I have a little dilemma with my laptop. I think the issue does not rely on my processor as other people have mentioned. tho here is the trouble im having, sometimes i get this weird stutter when i play music then switch to a full screen application like the video display in windows media player. Its very bother some coz i have a 1.66 core2duo processor and it shouldnt have this type of issues. Some has mentioned to me that configuring the cores may be able to help. My sound drivers are up to date so are my video drivers. Is there anything i can do to stop this problem on such a high end machine... btw, its has 2 gigs of ram, gforce 7600 with 256mb dedicated video card. Im not sure what i could do or how to configure my processor core so that my multimedia can transit smoother without interference.

 

I have this same problem. My laptop has a 2.0Ghz P-M with 2.0GB ram and the x700 with 128MB dedicated Vram. Any ideas why this happens?

Malikite009,
Do you use Notebook Hardware Control? I am wondering if that is causing my problem. I have it set to Dynamic so my processor normally sits at 800MHz. How it spikes up to 2.0GHz every once and a while. This seems to be when iTunes stutters on me.

Easiest way to test that is to turn off NHC and see what happens when you try the full-screen app again. Does the video display try to gain sound access? Or is it just video? Is it stuttering because the audio player doesn't buffer enough data from disk to make up for the lack of bandwidth from loading the video? Or is the video already playing?

 

how do i use the hardware control? I would try it to give you some result... and i dont think its a video issue because it comes with a dedicated 256. Maybe it just needs to be configured right..
ps, my old PC doesnt do this problem and its a 1.4 celeron, 256 raidion pci, sitting at 512mb ram.

 

I've occasionally noticed sound stutter on my desktop while I'm burning a CD/DVD. I can only imagine it has to do with high processor usage and integrated sound. I find it interesting that Tim mentions his sound stutters when his processor usage goes up. What else are you doing, Malikite, when you notice this problem?

 

Yeah I am pretty sure this is a processor issue. When NHC was set to max I didn't have any stuttering issues when listening to music through iTunes. However when it was set to Dynamic it would have stuttering issues.

My next question is why should it stutter when it is set to dynamic? Shouldn't it be able to adjust without stuttering?

You could probably prevent the stuttering by setting the task priority of the music playing app to high.

 

When using media player i am either just on the internet, but i dont get interrupted at all until i switch it over to full screen. I can only have window media player by itself and play music and still have it stutter. My IDE is set to "DMA if applicable" should i try to set it to PIO??? i have no clue what NHC means tho. sorry. Its frustrating coz i have a core2duo and thinking that its nice and powerful, it cant even run a simple player smoothly. The stuttering happens when the screen goes black then i hear the interuption. then everything is perfect till i switch back to normal windows... it only happens at that moment.

 

Yeah, integrated sound + high cpu usage *can* become a problem.

Have you tried with different audio players? (Winamp lets you control how much it should buffer, might want to play around with that setting and see if it makes a difference)

Does anything else stutter when you switch to full screen? Does CPU usage stay at 100% for a while when you do it?

And what happens if you set your audio player to run at high priority?

 

Nonononono, leave it at DMA, and doublecheck that it's currently actually running in that mode. (There should be a text field showing the mode it's currently running in somewhere nearby)

Also, switching to and from full screen mode can easily cause a bit of temporary stutter, regardless of CPU speed. I don't know exactly why, or whether it's specific to Windows XP, but it has to perform a bunch of work when changing screen modes, and that seems to temporarily block a bunch of things, meaning that if it takes too long, stuff like mp3 players will run out of buffered data, and stutter.

It might just be a Windows XP problem (and different video cards might take different amounts of time to switch between screen modes, so some cards might not cause stuttering while others do).

Just guessing here though. All I know is that it's not uncommon to get a bit of stuttering when switching between full screen and windowed mode in games, regardless of hardware. And so I'm guessing it's to do with Windows playing it careful and blocking all irrelevant I/O traffic while switching.

 

It appears that setting itunes to high priority did work. I would give that a try to see if it is the same problem for you.

well the cpu goes back down after incidence... it wont stay at 100 for a while... only if it freezes and it hasnt frozen yet. Im wondering if all laptops do this coz for the majority, most have integrated audio. it seems like the cpu uses alot at that moment and cant contain both processes evenly. Im wondering if i could configure my system so that i could see.
ps, even if set to high priority, it still stutters

PS. Im wondering how i turn off "NHC"

 

if you don't know what NHC is, then you don't have it installed and you don't need to turn it off. It's a utility for managing your laptop's hardware performance, which can be used to increase battery life. I've never used it myself, so if my description's not quite right, I'm sure someoen else will clear itup

 

thanks for clearing that up, but im stilling having this problem and its annoying as HELL!. Someone plz let in on some more insight to slaughter this issue and rest well with my notebook
