I just got a new cell phone and had two rather odd failures of electronic equipment.
My computer suddenly cannot make sound of any kind. This morning it worked, now it is absolutely mute regardless of the source - a CD in the drive or normal Windows sounds produce nothing. I’ve checked everything inside and out. The speakers themselves worked when checked with a radio. Nothing changed in the sound card settings.
I have a stand-alone DVD player hooked up to my TV. Same room as the computer, about six feet away. When I put in a DVD today the audio worked, but I got no picture. The TV was working - I could see the menus and such, just no video signal from the DVD. I cycled the power on the DVD player and it came back.
Seems beyond coincidence to have these two problems on the same day I get a new phone. But these two systems (computer and TV/DVD) are separate and don’t interract at all. Could the new cell phone be responsible for both?
