Hi everyone and thanks for answering.
My PlayOnLinux wine is 1.6.2 and in its winecfg Audio tab has Driver Diagnostics - Selected Driver: winealsa.drv
My system wine (the Wine installed before PlayOnLinux) is also 1.6.2 and its winecfg Audio tab has Driver Diagnostics - Selected Driver: winepulse.drv
Yes, it seems pulseaudio exists on my system. I ran
and the media player crashed after first command (pulseaudio --kill), then I could play sound file again after second command (pulseaudio --start)
I don't know if I have pavucontrol installed. Maybe?! Here is how my sound control panel looks like:
You are not allowed to view links.
And I can't open this sound control window while a game is running. Also, if I open it before a game is running in PlayOnLinux, the game again has no sound!
Again, my normal system Wine has no such problems. Only PlayOnLinux has.
P.S. Sorry I couldn't find a way to post the picture directly here. I'd appreciate any advice on this as well.
