Choice of audio output

From my MacBook Pro, when I listen to music, I choose on my Mac and in the preferences of HQPlayer4Desktop the right sound output that corresponds to my Wattson Audio.

I do not understand why this choice is not saved and switches to the speakers of my Mackbook as soon as I start the music.

Is a bad setting in HQPlayer the cause of this problem?

Did you click OK button in the preferences dialog?

Yes. The NAA control protocol is not supported by my Emerson Digital streamer. It is a problem ? From time to time, I use a Microrendering with NAA protocol which works very well.

the problem was not with HQPlayer. Here we go again !
