Mark had some good suggestions. I would try one of the cheap USB audio "cards" Might want to get something a little above the real cheap Chinese no name brands that have incomprehensible documentation. Sounds like the Mac is just too smart to use. Apple tends to think they know exactly what everyone wants and makes it impossible to depart from their program.
Did you do the command line audio hardware reset that was recommended in the link i sent?
I think you would be wasting your time trying to get Apple to fix the problem. You are not going to find a tech who knows anything about the requirements of the DKV. The only people who know that are Yamaha and Mark Fontana.

Thanks Spencer
I have not had much time to tackle the problem but it comes definitely from the Imac. I unearthed and old iMac G5 10.4.11 system from my basement which runs 10.4.11 os ans it plays faithfully the .wav files which are then recognised by the DKC and played perfectly: AH !So now why the much newer Imac isnt able to do that is a mystery . I ve done eliminating games and found that it is not a software problem (it occurs with all kinds of players), nor a hardware problem as far as I can see ( same result from phone jack out, usb audio out, bluetooth out) ... so Im a bit at lost and the machine not being waranteed anymore Im hesitant to bring it to a service center with such a precise and undectable flaw...Latest: I found that in the best cases the audio output is recognised by the DKC which outputs it but the sound is clipped like half second of music half second of silence, very regular and it goes on and on with NO midi piano part played though..In the meantime I upgraded the Imac to the latest Sierra OS and things are not working as it should ... I have to downgrade ... no time for all those exercises LOLRegards to everyone ; -)Alain
