Console Issues

I've frequently run into bumps and hiccups with my PS4. Many issues have sorted themselves or I found answers through online research. But sometimes, I can't find any smart answers.

I invite anyone to post any unsolved issues they've been experiencing with their home consoles here in the hopes that someone can provide a smart answer.

My own issue most recently was this: My headphones weren't working. I couldn't get audio. These same headphones worked in my PS4 a month ago when I was playing Destiny and they still worked in my phone.
I plugged my headphones into my controller and the message popped up onscreen, telling me I've plugged in a headset.
In Audio Devices, the volume was up and All Audio was set to the ouput device which was registered as my headphones. Yet, still no audio.

I just tried turning off my PS4 (not just rest mode), and when I turned it back on, the audio came back.

I was legit posting this in hopes of getting an answer to my problem, but I stumbled onto it myself.
