Figured my buzzing mic...

[Loki951]

Well after some help with research and google... I was able to formulate what was goin on... (Disclaimer: this is just FYI if someone has the same probs)

Symptom:
Mic picking up a hissing or buzzing. (when mic transmits) (Narrowed down to occurence when graphics were running anything above normal load)

Cause:
*Well on my the front of the P193 I have front mic/headset jacks and [internally] there is a long wire [from the front panel connection to the sound card] that seems to be REALLY EMI sensitive.
*So instead of using the front mic (where the wire runs directly above the pci-e slots of the graphics card to the creative xfi pci-e soundcard) I tried plugging straight to soundcard (DOH! Success!)

Comments/Suggestions:
Though the front panel is handy for quick connects I am thinking one of two options because I like my speakers as well as headset to be plugged in...
Option A- Run everything from the [back] soundcard and just get an audio 3.5 Y-connector so that both speakers and mic can run the audio out.
Option B- ANyone know how to retrofit that wire connection to the front panel from the soundcard because its really close proximity to the top (bottom) of the vidcard. What I mean to say is, anyone know of EMI dampening material or whatnot?

If I knew you where having problems I could have told you not to use the front /side(but near the front) connections.

This has been an issue with just about every single case ever made but there are now a few cases out there for the PC builders that have re routed the cables to not interfear with the motherboard.

If anyone wants a list I will try and find it for them!!!!

You can try EMI shielding electronic heat shrink tubing. If that is not practical in your case, you can also use other EMI shielding products like foil wraps, mesh, cloths, or tapes. I don't know how they will perform for your use, however I can tell you that they work excellent in many special operations applications especially when building explosive charges for dynamic entry. We have used these products when we needed EMI shielding as well as protection from other elements such as environmental, abrasion, chemical, acids and alkalis, etc. They have performed well for us.

Excellent input guys. Thanks. Yea I am thinking for being short and easy to access Ill just radioshack the y-connection for the speaker output slot for both headphone and speakers. I will however just for 'sh*ts and giggles" check out your suggestions Sonic. ::thumbs up:: Agreed on practicality but cool to know things are out there when someone actually knows 1st hand.

Loki, I agree with you 100%. Why worry about the front jacks when you came up with a quick solution that is even easier! Thanks for sharing it with everybody! :)

You could try to cut and lengthen the cables to re-route around the "noisy" devices. Otherwise you need to shield it from the EMI as the others have stated. Check out Mu metal, it's used a lot of times in vehicles to shield wires/equipment from EMI.
