I hear ya - kind of a mystery how it got changed then. In windows the event viewer would log device errors or warnings. I'm not saying it's worth chasing down... you can easily get pulled into the rabbit hole. If you've got it working, that's what counts I guess...
FWIW, I do a cold boot at least once a day (shut down -> pwr on)
Yea I will if it happens again, working so far so just gonna count it as a fluke and or a possible result of the update I just let rip and move on!
I tend to cold boot once a week or when I make a change I want to make sure takes. I reboot every couple days or so, I restart it then the software when I call it a day. Neither one for this issue and I probably should have. It was pretty low on my "problems to look at" list especially with that big wind we had last couple days.
We got lucky couple trees down lost a few shingles on some of the buildings, nothing like what others suffered from it.
Prayers for them and their families.
Anyway this thread, it reminded me of the no sound issue so joined in.
