Yes, pavucontrol work now, I do not know why, but it can not work 
before, it just load the screen and hang.

because pavucontrol not work before, then I think it is not firejail 
problem, but actually, the problem is smplayer with firejail.

I am really sorry for waste your time.

If I run smplayer/mplayer without firejail, the sound work as normal.

Thank for you help, thanks.
