Im new on Centos
I recently installed Centos 8 and i have the following problem with my

I cant play media on the browser.

for example i cant play.

Or i cant listen shows or songs on mixcloud.

for example 

i get the message 

"Sorry - your browser is not supported.

Please update your browser or install another such as Google Chrome.
Mixcloud requires HTML5 audio with MP3 and MP4 support."

I suspect that these 2 problems relate.

Any ideas how to solve this problem?

Thanks in advance!
