This weekend I take work home. And the issue gave me a little headache. Look not learn, that when you get home should forget about the problems of labor and should stop thinking about those things.
But there are times when no choice but to try at home some things that end up going fine at the store. We shop two PCs with TV tuner card. Normally in the satellite store we have there are able to tune installed nearly 700 channels. But on Friday we tuned only 80 channels. And did not look good. As the error was on two computers at once, because we thought that perhaps the problem was on the roof. So I take one of the PCs in my house to prove it plugged into my dish.
I placed the computer in the living room and plugged it into my TV. Wait to be alone, and had a great silence in the house. Connect your computer and begin to hear an unpleasant noise. I mosque, because the computer shop could not hear anything. It was a HTPC with a Core i3 was not any noise. Yet there if it made noise. While leaving the team tuned satellite channel, which began to look might be the source of the noise. I got the worst. As in my house at night there is silence, so I thought that was heard in the store computer.
In the end, I ended up removing the HTPC and trying to locate the source of the noise. I looked to see if moving the team from the shop to my house a cable had moved and touched with a fan, or if items had fallen loose and was vibrating a bit now, creating the annoying buzz that was heard. But nothing was quite right. No playing with the fan cable, power supply, hard drive, or burner … everything was perfectly caught the box. Even looked at whether there were any in the rewritable disc and the noise came from there. But there was no way. He turned off the PC and the noise disappeared, lit up and be heard again.
After spending half an hour reeling, located the sound source. My HTPC is connected directly to cable stereo SPDIF. But this team had plugged through HDMI to my TV. The TV volume was placed at 100% and what I heard was static coming from the HDMI cable from the PC. I removed the television volume and the annoying buzz is gone. Thank goodness, because I was sleeping there without struggling with the HTPC.

Why don't you make one?
