Both speaker systems sounded great plugged into the audio out of an old laptop, so I knew then that it isn't the speakers.
BUT....the speakers are powered and the headphones are not. (ground ?) I have uninstalled\installed sound driver. Twice. My wife does like to buy energy saving bulbs (I hate them) and I did turn off all lighting a couple of times when experimenting. I'm the most puzzled by the difference between the rear port and the front port. rear port- low frequency hum from subwoofer. Speakers sound clean. front port- high pitch squealing in speakers-- subwoofer sounds ok. Zero low freq noise. I am glad that until I solve this they are at least functional. Using the front port, the squeal is only audible when speaker volume it turned up about half way. I can max out the volume in windows and keep the speaker volume at almost the lowest level on the speakers, and that still gives me a pretty good amount of sound. I cannot stand to wear headphones for very long. Next..will try to borrow an old sound card from someone. I WILL post if\when I resolve this. And......thank you for the help. MUCH appreciated. |

I only have ATI overdrive to monitor temps. It never gets above 58C there.
The energy saver bulbs have a flourescent coil inside. I know...they don't have a light starter like your friend but since you brought up lighting I just wanted to mention I had even tried killing the lights just so I could rule them out. Hell, I killed everything using juice on this circuit breaker at one point or another. I will endeavor to persevere. |
