background Hum during mouse movement

Sammydad1 · Oct 29, 2003, 09:38 AM

Hi,

I am running KX .3535 on my XP Pro sp1 based system.

My motherboard is a Biostar M7NCD Pro (0630 BIOS). CPU is AMD Athlon XP2500+, 2 x 512 MB PC3500 RAM, VisionTek ATI 9100 based video, SB Live 5.1 XGamer sound card,... Also a Hauppauge TV Tuner card with its audio plugged into the CD Input of the sound card., PS/2 optical mouse, multi-media keyboard, Creative 5300 5.1 speakers.

I get this very quiet but discernable hum/rumble noise during mouse movement, and I think it also happens during hard drive access, but it is more pronounced during mouse movement.

It also seems to be heard as I am writing this note, almost in response to all the little icons and advertisements flashing about.

Do I have some setting wrong ?? The hum is subtle, yet somewhat annoying at those times when I expect the audio to be quiet.

If I Mute the AC97 on the Ins & Outs screen, the sounds go away. But then I can't use my TV Tuner because the audio is running thru the sound card.

Any ideas ??

Dave

This may sound really weird but try loading the plugin REVERB R, from Max's effect's package (you don't need to connect it to anything) and watch if the noise goes away. Just do it and tell me. It solves the problem for me but I really don't know why...

Hi,

Ummm... Where are Max's Plugins to be found ?? I looked thru my KX stuff and it has Reverb Lite installed now. I have not pushed my KX driver very much so I am not fully up to date with where other things are located.

Thanks for your quick reply.

You can download them right here: http://www.electricstart.de/kxdrdir.htm And you can find the "offical" thread to them here Plugins in Uniform ("UFX")

I forgot to mention... You have to click on the FX IN UNIFORM 3534 (EXE) link to download the plugins. Them click in the file you get to register them with KX mixer. After that restart your computer and they'll be available (if you get an error message, ignore it).

Hi Sammy!

I think, this is an other problem. You said, if you mute AC97 then the hum is gone... so I think, you have a noisy and bad shielded cable between any external device (CD-ROM, TV-Card or others) and the soundcard. So try to mute the separate inputs of AC97 (leave the master open) and look where the noise is coming from. Then try to improve the corresponding cable connection (get it away from CPU and power supply or HD or get a high quality shielded cable) and finally try to tweak the sliders to get an improved signal to noise ratio.

Good luck for it!

I just wanted to second TravelRec's diagnosis. I've noticed that analog CD-ROM audio cables between a CD-ROM drive and sound card often pick up RF interference from the motherboard, and having the CD Audio channel unmuted will often result in audible noise of the kind that you have described.

Daniel Drummond · Oct 30, 2003, 06:48 PM

In windows xp there is absolutely no need for the cd-rom audio cable, as winxp reads the audio digitally. So you can just get rid of it.

I had similar problem.
I have found the reason-it was caused by TV card which usualy has very sensitive amplifiers inside.
Such amplifiers amplify the whole magnetic shield which is inside PC.
After small "hand-made" activity (metal box grounded over this card + changing cables) this sound effects was gone.
At least I don't hear anything.
If you are not good in "do it yourself" job you can always think about TV tuner which is outside the PC box.

>> If you are not good in "do it yourself" job you can always think about TV tuner which is outside the PC box.

The only problem with those is that many of them have to buffer a couple seconds of data before sending it to the computer due to the fact that they use lower-bandwidth communications like USB instead of having direct access to the PCI bus. This means that you can't hook up video game consoles to your PC through them because the video and audio show up on your monitor a couple seconds late!

That has been my experience with USB v1 external TV tuners, so USB 2.0 or FireWire tuners may not have this problem anymore...

Aykroyd · Oct 31, 2003, 04:59 PM

I guess today only USB 2.0 can be found
Or at least should be chosen
