The other day I was getting a bit of static, so I fumbled around with cord and got that to disappear, though there was a slight, low hum. It wasn't heard when sound was coming from the speakers, though a bit annoying when they were on but just sitting. No big deal turning the speakers on and off -- though it was more inconvenient than should be the case, and also the sound has been somewhat low lately. I figured that it might simply be the case of an old pair of speakers on their last round-up. Nonetheless, today I dove back under my desk to play around with the cords again, just in case I could fix things..
Thanks my technical expertise, I figured out the problem. When I had been futzing around with the cords a few days earlier the time before...I hadn't plugged the cord back in all the way.
I have now done so. And all works well..
Which brings us to today's tech tip. "Make sure to insert your plugs in all the way."
