Couldn't create or open audio filter 'drc'
Error at audio filter chain pre-init!
Audio: no audio
Definitely it's caused by the removal of the drc. Turn off the volume normalization in preferences -> general -> audio but also turn off the option to remember settings for all files in preferences -> general. Otherwise smplayer will still try to use the drc filter with the videos already played before.
Another way, add --af-del=0
in preferences -> advanced -> mplayer/mpv -> options. (This disables all audio filters).
Or you can download and compile the version of smplayer in svn, since the problem is already fixed in svn.
