Audio does not work in Windows 10

I just upgraded to Windows 10. Have a problem with audio.

When I invoke audio like this:



in html (Dreamweaver) it plays in Dreamweaver’s browser, but does not play when compiled.
What format should I use that will work in Windows 10 and earlier?

(The above format worked in Windows 7).

Sorry, for some reason, my pasted HTML code does not show up. It’s this:

audio id=“player” controls=“CONTROLS”>
source src="…/audio/audifile.mp3" type=“audio/mp3” />
/audio>
To make it print, I have to drop the right bracket at the beginning of each line.

Do you have a firewall that could block internal HTTP connections on Windows 10?
