ass subtitles

I am seeing a lot of Matroska files with ass subtitles. I have to turn them on manually. (Play/Subtitle) Is there a setting in MPC that will auto load an ass subtitle when the video starts??

During installation of the codec pack there is a page where you can specify your preferred languages. There is also an option to show subtitles when audio is in your primary language. Enable that.

I have done that but it will show every other type of subtitle (embedded, SRT, SUB) automatically when the video starts to play.  However if the "embedded sub file is ASS I have to go in and manually select it to get it to display.

I have observed that VLC will not auto load ASS either.

Subtitles are shown by default if they match your preferred language(s), or if they have the "default" flag set.

Right-click on one of those files in Explorer and click on MediaInfo in the contextmenu. That shows details about the file. Copy that here. Then I should be able to advice on how to configure to select it automatically.

I have looked at several and they all seem to be in this format;

Text
ID : 3
Format : ASS
Codec ID : S_TEXT/ASS
Codec ID/Info : Advanced Sub Station Alpha
Duration : 42 min 24 s
Compression mode : Lossless
Writing library : Lavc57.106.101 ssa
Default : No
Forced : No

This should solve it:
In the settings of LAV Splitter you have a line where you can configure which track is selected.
Add this to the end of the current value: ",*:und" (without the quotes)

I went into LAV Splitter but do not understand where I should make this edit. Could you please advise.

thanks you Sir, that worked
