I have 3 USB Sound cards on my PC, want to select a specific one of them to play a audio file ( wav/mp3 ) ! Is it possible ? , How. ( as well as in B4A !).
( The main Idea is to Play 3 Audio files in the same time but each on a different OutPut. )
It might be possible by extending my Vlcj-wrapper however that requires that you use VLC as MediaPlayer and it might be an overkill for your purposes. Last time I read about it, there seems to have been in bug in Vlc that prevented it from working correctly but it might have changed by now.
