We have had this crazy humming/feedback sound coming through our stereo whenever we play anything from our computer. It wasn’t always that way.
It has been driving my normally sane husband quite crazy. We just had that installed about a month or so go. Coincidentally, that was when the hum started. So today, we finally decided to tackle that annoying sound. After some thorough diagnostics, a few debates and some ha-ha moments, we realized that the noise is coming from the darn cable.
Luckily, we did a simple test to see to confirm it was the cable line. We hooked up a TV matching transformer to a UHF-to-cable (antenna to coaxle cable) converter between the cable line and the cable box. I’m a bit of a pack rat, so I actually had both pieces in our garage… you really never know when you’re going to need something. 😉
Anyways, it worked… well, sort of. The hum was gone – definitely a good thing. But the cool features of our cable box didn’t work (like On-Demand and DVR). Luckily, Amazon is coming to the rescue. We found a VSIS-EU Cable TV Ground Loop Isolator that should do the trick.
Let’s hope it works!
UPDATE: It worked like a charm! Absolutely no feedback on the stereo. This was my husband’s favorite Father’s Day gift!
