smplayer audio does not work

[dusan]

Hello,

I installed smplayer-19.10.0-1.el7.x86_64 on release 7.7., but unfortunately audio does not work.
My uname -r : 3.10.0-1062.4.1.el7.x86_64

My log file:

Can you help me?

Thank you very much in advance.

Which backend is it using, mpv or mplayer? If you just use the backend, e.g., mpv <filename> do you get sound?
Do you get sound otherwise, say with youtube in firefox or chrome?

I am using mpv. But the problem is already solved. The reason: I used various releases for smplayer (this one from
rpmfusion-free-updates - smplayer-19.10.0-1.el7.x86_64), and mpv (this one from nux - mpv-0.23.0-2.el7.nux.x86_64).
It is necessary to use always only one repository...
