Worked perfectly 2.0.0-2.0.4, 2.0.5 - not. Did API changed or what ?

I think it's the other way around. Audio track selection did not work before version 2.0.5.

"Worked perfectly 2.0.0-2.0.4, 2.0.5 - not. Did API changed or what ?"

I am also having an issue. In 2.0.5, libvlc_audio_set_track() is returning 0, even when it fails to change the audio track. It also fails to change to track 0.
In a situation with where libvlc_audio_get_track_count() tells me there are 3 tracks, I get the following:
libvlc_audio_set_track(media_player, -6) ; // returns 0, no change in track
libvlc_audio_set_track(media_player, 2) ; // returns 0, current track becomes track #2
libvlc_audio_set_track(media_player, 1) ; // returns 0, current track becomes track #1
libvlc_audio_set_track(media_player, 0) ; // returns 0, no change in track
libvlc_audio_set_track(media_player, 3) ; // returns 0, no change in track
libvlc_audio_set_track(media_player, 5) ; // returns 0, no change in track

Hmm, in fact the return value is undefined on error in version 2.0.5. That will be fixed in 2.0.6. In the mean time, you'd have to check libvlc_audio_get_track() if you need to check for errors... Other than that, it should work just fine.

Make sure you are using the correct track ID.

Thank you. I will do that.

OK, thanks. It appears that a change was made and the "Disable" track is now -1, instead of 0. I'll adjust accordingly.
