Urgent.Need advices on how to prove DPC latencies

Hi,

I have a Studio laptop. I had some issues with FLstudio+ASIO drivers, constant clicks/pops(the ASIO "overload" indicator blinks at each click/pop), no matter what latency I would have set. The smaller the latency the more clicks/pops per minute I had. All of this happened while using the standard Vista driver for the soundcard(used it because it sounds better, and the internal speakers have a higher max volume).
I started arguing with the salesmanager about this problem, and I was asked to come and prove it.

Today I've reinstalled Dell's audio drivers for the soundcard, and now the clicks/pops have a much smaller intensity, untrained people wouldn't notice them, especially if the music passage is complex. But I do notice them.

Now I need your help to suggest me some software that would prove better that the laptop has issues with realtime audio/video streams. I need to have a strong case in order to convince them.(I'm asking it because at the moment I'm not using heavy software, but, in the future, I couldn't afford it not work)

My DPC latency looks like this:
Occasionally I get some red bars, too.

 

Yours actually looks pretty good, do you have a Studio 15? Before the A09 BIOS was released, There would be a large (4000+) spike every 3-4 seconds caused by ACPI.

 

My Studio 1535 has ridiculous DPC latency, with red spikes every 4 seconds well over 4,000μs. This is with the latest BIOS, which is only A06 since Dell apparently cut off support for the 1535 in December of last year, when they replaced it with the 1537. Ah well. It was nice to get two months of support out of it.

Hopefully my 1555 will do better. I don't see why the DPC Latency tool wouldn't be considered proof...I mean, that is the software's purpose.

 

It is better, indeed. The previous BIOS was a complete disaster, I couldn't even play FLAC files without hearing pops/clicks.
The latest one is better, but still not good enough, with the VISTA audio drivers(which sound better) I get constant clicks/pops when using low latency software(FLstudio+ASIO/foobar+ASIO+Izotope/etc). Yesterday, I've decided to reinstall Dell's audio drivers, and I still can hear the clicks/pops in FLstudio+ASIO, even tough their volume is lower. The problem is that an untrained person would not notice them very clear.
And, as I said, I was asked to come and prove my problems in order to switch to a better laptop.

 

Show them the screenshot from the DPC latency tool, or even better, run it directly in front of them. You can also try experimenting with the waveform display in Audacity or something similar, so that you can visualize these clicks and pops.

 

I need something less abstract, an intensive audio/video software, so that they can hear/see the DPC Latency issues.

 

have you read this?

What should I read there?
I remember fast reading that topic a while ago, and there wasn't a proper solution.
I've tried many things, as I stated here:

There is an interesting image in the topic you suggested, I'll repost it here.

Please help with suggestions on how to prove the DPC issues.
I can't afford to have problems with them in the future.
I need to convince them to upgrade to a better laptop.
