Yesterday, left my computer. Video site was on Opera (The Web Browser). All was well.
Today, I return.
Opera is silent.
Irrespective of the site, Opera will not play a video-clip's Audio track(s)
Opened Microsoft Edge
Works Fine.
Searching for answers to this on the web; I find...
- A troll exchange on the Opera Website Forums
- A You-Tube clip which shows the silent-speaker thing on the Opera Page Tab (which I tried; result: fail)
- Link-Bait to infect my machine with the app to fix everything on my Windows 10 machine (yeah, uh-huh)
And on and on and on with useless stuff.
I am aware that Opera has a very small; tiny, actually; market share with respect to internet users.
The two sites I tried were: YouTube and Rumble
Same results on both; Edge works, Opera won't play audio.
Please point me to the proper place for this discussion and I'll take it there.

Does anything else play audio, or is it just Opera?
In Chrome, sites are / can be muted by default - is it possible that Opera has just caught up to that? Try right clicking the tab and see if there is an "unmute site" option.
Have you checked which audio output is in use? Mine recently switched from USB (headphones) to jack (soundbar) for no obvious reason (though I suspect the cat did it because I wasn't giving him food when he wanted it) which confused me until I switched it back.

Other audio applications work; Goldwave is perfect. Microsoft Edge plays the exact same video clips (same URL and everything) just fine.
Opera just went silent in the past 24 hours for reasons I don't know.

Oh boy, using your question as a prompt/inspiration, I used the Opera Help thing (I think) and asked about "Sound"
Got this...
How do I fix video playback issues - image, video or sound doesn’t work or works badly?:
That usually indicates a GPU problem. Check the drivers for your graphics card. You can also try enabling or disabling the Hardware Acceleration function. Go to Settings > Advanced > Browser > System and enable Use hardware acceleration when available.
With another Link that I can click to, "...Read more about crashes and issues..."
I am highly suspicious that this would be barking up the wrong tree, as everything was okay 36 hours ago

Was that opera ? I could not find the anything about USB headphones over here

Does the volume mixer show Opera at the same level as the rest of the programs?

DUH !
You fixed it.
Of course, I had to use my Super-IQ-Genius brain to find the mixer in the first place; honestly, I do not remember how I made it appear on my screen. Thank you Microsoft for adding yet another IQ test obfuscation to make things idiotically more difficult.

The question remains in my mind: When did I change that ?
Or perhaps, even more relevant: How did that setting change ?
I don't remember ever looking at it; certainly not in the past week or two.

Have you considered using the built in browser?

Yeah, the Microsoft Edge Browser ! What a great idea !

I have a little graphics library for IoT: GFX (htcw_gfx)[^]
I originally targeted C++17 but the Arduino toolchain did not have a new enough GCC version to support it. I had to fork it a bit to support C++14.
One reason was a massive function that is computed 90% at compile time down to a very few asm instructions. Which depend on how you call it which is why there's several pages of code.
What it does is convert one pixel format to another, including doing things like grayscale or HSV conversion.
The trouble with C++14 is it couldn't do the entire function at compile time. With C++17 the compiler can run the function so if the color value is constant there is no runtime overhead for doing the conversion.
The bottom line is a bit of a performance win since this function is used all over the place for virtually every drawing operation. If the user passes in a constant color value, which is typical, the conversions no longer require any runtime overhead!
Gosh that's neat, and one of the reasons I love C++ so much, and every version keeps allowing the compiler to compute more and more during the compile phase. It's actually kind of amazing how much you can get it to do. I joke that the C++ compiler will make your bed. There's no other language like it.
Feeling pretty good about all this. It's deeply satisfying.
Here's something C++17 can do at compile time if all input values are known at that point:
const int CVACC = (sizeof(int) > 2) ? 1024 : 128;
using trindexR = typename PixelTypeRhs::template channel_index_by_name<channel_name::R>;
using trchR = typename PixelTypeRhs::template channel_by_index_unchecked<trindexR::value>;
using trindexG = typename PixelTypeRhs::template channel_index_by_name<channel_name::G>;
using trchG = typename PixelTypeRhs::template channel_by_index_unchecked<trindexG::value>;
using trindexB = typename PixelTypeRhs::template channel_index_by_name<channel_name::B>;
using trchB = typename PixelTypeRhs::template channel_by_index_unchecked<trindexB::value>;
const auto chY = uint8_t(source.template channelr_unchecked<chiY>()*255);
const auto chCb = uint8_t(source.template channelr_unchecked<chiCb>()*255);
const auto chCr = uint8_t(source.template channelr_unchecked<chiCr>()*255);
const int cBA = chCb-128;
const int cRA = chCr-128;
const auto cnR = (uint8_t)helpers::clamp((int)(chY + ((int)(1.402 * CVACC) * cRA) / (float)CVACC),0,255);
const auto cnG = (uint8_t)helpers::clamp((int)(chY - ((int)(0.344 * CVACC) * cBA + (int)(0.714 * CVACC) * cRA) / (float)CVACC),0,255);
const auto cnB = (uint8_t)helpers::clamp((int)(chY + ((int)(1.772 * CVACC) * cBA) / (float)CVACC),0,255);
const auto r = typename trchR::int_type(cnR*(trchR::scale/255.0));
helpers::set_channel_direct_unchecked<PixelTypeRhs,trindexR::value>(native_value,r);
const auto g = typename trchG::int_type(cnG*(trchG::scale/255.0));
helpers::set_channel_direct_unchecked<PixelTypeRhs,trindexG::value>(native_value,g);
const auto b = typename trchB::int_type(cnB*(trchB::scale/255.0));
helpers::set_channel_direct_unchecked<PixelTypeRhs,trindexB::value>(native_value,b);
good = true;
Just amazing. There's actually compile time computed bit shifts to get and set channel values behind that mess. *shaking my head*. It's incredible.

I am reminded of a quote attributed to David Gries[^] of Cornell.
Gries said: Never put off to runtime what you can do at compile time.
I had the pleasure, ca 1982, of attending a University of Wollongong Summer School where Gries was one of the presenters. He pretty much ran us through his book "The Science of Programming", about the mathematical proof of algorithms - loop invariants, progress, termination conditions etc.
And yes, the title of the book is a light hearted reference to Knuth.

I'd tweak that quote to use should instead of can. Some things are better left until runtime so they can be configured rather than hard-coded.

do you have an example? I think it's memory vs speed. How dll's were born.

Reading a configuration file instead of hard-coding things is an example. Even just waiting until runtime to allocate an array qualifies.
When C++ calculates things at compile time, it's usually a case of using more memory to run faster, at least when templates are involved. And a DLL is the opposite, running slower to save memory.

You are right, configuration files would qualify.
