Suddenly, my Ubuntu 18.04 is not capable of streaming any media online through a browser (any browser).
But I still can play any kind of video through VLC if I download them. I can also stream videos through VLC normally (even youtube videos)
But even on VLC, there is no sound. Only video.
I have tried the testing videos located on this link: https://www.quirksmode.org/html5/tests/video.html
I have tried audio on this link https://hpr.dogphilosophy.net/test/
And I couldn't play any of them through a browser but I was able to stream them through VLC but without sound.
I have tried all the obvious solutions that I can think of like updating my graphics card driver (which was really out-of-date) and installing the codecs. But my problem has remained exactly the same.
Any help would be appreciated.
