Help..No sound on mac

[desire4acuity]

Hello my dear frinds,

really hoping to get some help as I searched over the internet and nobody literally NOBODY has this problem. So, sounds when MAc starts is okay, and all internal sounds, but when i play any video on youtube, downloaded movies,netflix etc its all muted.
i went to sound preferences seems everything good all sound is up and nothing is muted.

this happened right after i downloaded real player recorded to download movies from netflix an donce i uninstaleed it this happened.
Tried to restart turn off reset SMC and nvpm nothing helps.

Any suggestions?Thank you

What, exactly, was it that you downloaded and installed? From where did you download it?

Well, to start, you should remove "real player"...?
Is that the "real name" of the app?

How I would advise you to get rid of it:
Download the free little app called "AppCleaner" from here:
https://freemacsoft.net/appcleaner/

Put it into your Applications folder.

Now, do this:
1. Open AppCleaner
2. Open your Applications folder in the finder
3. Find the "real player" app and "drag and drop it" over AppCleaner's window
4. AppCleaner will "look around" and gather up all the components of real player
5. Scroll down through the list to make sure that everything has a check mark next to it.
6. Click the REMOVE button. You may have to enter your password.
7. AppCleaner should put all the junk into the trash
8. Quit AppCleaner and EMPTY the trash
9. RESTART the Mac.
10. Get to the finder. Are things any better now?
