Q: Upgrade El Capitan : no functionnal airplay

Helle everyone,

Just for information :

Here is 2015 MBP 15" Retina connected via wifi to  Airport Express 2d Gen 2015 :

VLC airplay drops contantly

Audirvana : impossible to select airplay, does not see it

Vox : does not see airplay either.

When airplay selected through the system audio pref : nothing plays : silence.

When I select airplay from Vox, it adds another airplay in sound preference, which gives me two airplays with the same name. Not working either.

Everything worked fine prior to El Capitan upgrade, and everything is configured as it should be. (20 years a mac owner, and technician, I know my stuff)

I guess the more we share our issues, the quickiest Apple may react with a correcting update.

I'm stuck with my 2T music library that I can't play on my hifi system anymore and that ***** !

Apple please consider the issue and provide us customers with a fix !
