HP Pavillion dv2000 - Integrated mic problem

post #1 of 13

Thread Starter 
I have a 2 year old HP Pavillion dv2000 running Vista with an integrated webcam and microphone. They both worked worked perfectly until about a month ago, when the microphone started "clipping" in every recording program I would use it in. For instance, in Acid Pro, the mic input level will be maxed out, and after attempting to record, the playback is just really loud, obnoxious jumbled static. I have attempted to adjust the recording settings in Windows, but nothing works. I have the mic volume set at 50, which is what it was at back when it was working. I even returned all settings back to default. This may have started happening after a Windows Update, but I can't exactly pinpoint any instance of when it began. It says my drivers are current. I even uninstalled the device, and then reinstalled the drivers, but it's still doing the same thing. Any help or suggestions would be appreciated.

It seems hardware problem, mostly by cable. If you have front mic port, try to use it to see if problem go away. Integrated webcam and microphone's cable run under the LCD and the hinge, then connected to motherboard; it might be get demaged over time, especially with bad assembly at the LCD cover and the hinge cover on the left side. LCD and wireless cable usually go out from the right side of the LCD.

If you have a restore point, try to go back before the updates and see

I did try another microphone plugged in through the front, but it does the same thing. And the only system restore point I have, is from yesterday, which will do me no good. I'm almost certain that the problem is software related, as the microphone never started "going bad". You would expect a faulty cable to get worse over time. But in this case, it just worked one day, and not the next. It's very strange. I'm trying to think if it might be conflicting with something but I can't think of anything.

A fauty cable of the built in Mic might cause static noise even when you're using the front Mic. I suggest you try to unplug the cable of the built in Mic on LCD while using the front Mic to isolate the problem. It's under the Quick Launch buttons cover and on the left side.

My Quick Launch buttons look like this: http://www.cooltoyzph.com/img/librar...%20+%20CTL.jpg
How should I get under there? Do I need to remove the entire speaker cover?

Here is the manual for DV2000:
http://h10032.www1.hp.com/ctg/Manual/c00729555.pdf

So I suggest you disconnect the built in MIC first to isolate the problem and to see which MIC is the source of static noise. After disconnecting the built in MIC, put the cover and keyboard back temporarily and test the front MIC. The souce of noise may be come from other components, but this is the first step to find the problem.

I ended up just removing Vista from my computer and replacing it with Linux Mint. Now the microphone works flawlessly, so it was some sort of weird driver issue or something. Thanks for your input, and I wish I had a Windows solution to post for anybody else who might have the same problem. Unfortunately, the only fix I can suggest is changing OS's.

How about re.installing Vista, now that you wiped it out completely, and start from scratch. Keep an eye on what apps/drivers you will be installing and recheck the audio as you go.

You can have a test with your laptop by another hard drive. Notebook hard drive is cheap now especially used one under 100GB. Software problem is not difficult to fix. You can try XP as you wish as it runs a lot faster than Vista.

With my persoanl experiences as a vista beta tester from the start, and with the latest toy that a family member just received (Asus, Vista HOME 64bits, running WoW at full speed with ZERO hiccup), I believe that statement like "XP faster than Vista" (or vice versa) should be taken out of any general contexts. There are just so many configurations out there to even believing in reports, tests ... unless one must try it all oneself.

Not from my personal experience but a lot people want to downgrade from Vista to XP. In the same HP laptop, XP loads a lot faster than Vista, especially the one with too many HP's bloatwares. Many will hate Vista when facing application compatible issues, especially your old favorite softwares.
I personally disable all of HP's bloatwares as it takes too long at start up. Run your own XP and compare it with Vista+HP's bloatwares, you'll see the big differences in the same laptop.
Also, I have dual boot of clean installed Vista and XP on the same HP laptop, XP still runs faster and it doesn't take much system resources as Vista without HP's bloatwares.

In respect to the OP and the thread theme, I would only reply to this once. There are threads in Notebook General/Software and Vista to discuss further XP vs Vista ..

Running triple boot (XP, Linux, Vista SP1 32bits Ultimate) on my old eMachines M6805. There are no issue with incompability with so called "old" apps. There is a thread on this in the Gateway/eMachines section, dated back to the first day of Vista beta.

Quite unfair comparison, if I remember correctly, users used to say the same thing with W2K (or Win98) vs XP and Bloatwares.

Vista is being considered the best resource management OS Microsoft ever puts out, liking it or not liking it. And with proper software updates and correct driver, the same app would run the same under XP and Vista. I have a personal experience earlier today, playing WoW on a 64bits Vista basic machine, that blew out my other XP gaming machine playing WoW, in this particular game.
