Pierre:
GG made a mod that is a slight improvement. If you have time, please check it out. There is a Mint 18 static tar at:
And a Ubuntu 16 static tar at:
Here is how it works now (at least I think I got it right in testing):
Gang None - same as always
Gang Channels
- the first audio track "Play track" rules all audio tracks; so if enabled then that track + any enabled associated audio tracks will play while the disabled ones will not play
- the first audio track "Play track" rules all audio tracks; so if disabled then no tracks will play
Gang Media
- all audio tracks will honor their states; so if an audio track is disabled then it will not play and if enabled it will play
In Gang Channels mode, you may notice that there is no way to not play the first track while still playing the others. However, Gang Media allows for this. There was no easy way to account for this.
I have not checked the Video tracks to see if they follow the same rules.
