Noise Coming From HS50m When Connected To Pc

[mrbean15]

I'm having some high pitched noise coming from my Yamaha hs50m monitors when i plug them straight into my pc, but if i plug it into my ipod, there's none of the high pitched squealy sound...  Does anyone have any ideas on how to get rid of the sound?  I'm plugging the monitors into an HT Omega Striker via a stereo to quarter inch directly.

Try a sheilded cable or a ferrite clamp on the cable ,  or get a extenal soundcard.

well speding more money on a new soundcard is pretty much out of the question, but i've never heard of a shielded cable or a ferrite clamp.  Can you please explain what these are and what they do? Thanks for the help =)

 
 
edit: i read a little bit, and i saw a shielded stereo extension cable.  Can i use that to plug into my pc and from there plug into the stereo > 2 quarter inch and then to my monitors? or will i still get the white noise?

well here's an update.   It turns out i had 2 ferrite clamps in my drawer of cables, and i put them on.  They seem to do the job pretty well, but i can still here about 1/5th of the noise i heard before, but it's not completely as silent as it is when i hook up my ipod or i leave the cable unplugged.  Is there anyway  to get rid of all of the noise?

Yes a shielded cable, with a twisted pair configuration , a shielded cable is a cable that has a foil / copper layer under the plastic jacket to block out RFI, a twisted pair configuration means the wires inside the cable are twisted together this design rejects RFI.
What cable are you currently using?.

i'm currently using this cable to my monitors

high pitched squealy sound is your sound junk being improperly shielded/grounded. I had this in my laptop, and I insulated the sound card with electrical tape from anywhere it may have been grounded.

 

[mrbean15]

how would i know how to ground/shield anything, i've never had any experience with this kinda stuff before

I didnt/dont either. I literally took apart my laptop according to the crap i found online, then I unhooked the sound card and saw where it bolts in or w/e, and everywhere it touched, I padded it with electrical tape. Then whatever was still showing, i wrapped with electrical tape. I even covered the screw holes and then tightened the screw through the E-tape into where it attached to my chassis. Do you have a laptop or a desktop? Does it have a dedicated sound card or does it plug directly into the motherboard? Pics of the inside would help

A external soundcard is the easyest way to solve your problem , you don't have to spend loads on 1 what about the behringer uca202 doesn't cost much more than a new cable would.

it's a desktop with a dedicated card (HT Omega Striker 7.1)  i'll upload the pics in a sec
 
inside the case, cable goes to front panel header with headphone/mic ports

Try moving it to a slot away from the power supply. This is just the mcguyver in me, but you can also try to take some sheets of tin foil and duct tape/electrical tape and place it around the sound card. Keep in mind, I dont mean to have the tin foil exposed at all.random metal in a PC case is bad. I mean take tin foil, wrap it in duct tape so as to make a tin foil sandwich with duct tape buns, and wrap that around your sound card. See if that fixes it. Moving it away from the PSU shoudl do wonders though.

 

[mrbean15]

well the onboard sound still gives me the noise, so i'm not so sure it's the psu's fault

 

 

[shrimants]

onboard sound is even dirtier power source after traveling through all those wires. I'm tellin you, try moving the sound card away from the power supply, you got all sorts of wires rubbing up against it and all.

ok, i'll try it later tonight when i have time =)

edit: maybe tmrw =(  would the next pci slot up be enough?
