We have become aware of a change in the way DPS Plugin for Mac interacts with Airplay in El Capitan (osX 10.11.) For users connecting to Airplay via Apple TV, DPS does not “see” Airplay as an output device in El Capitan unless you have connected to your Apple TV via Airplay Display.
It is unclear if this change will be fixed in a future update of El Capitan, but we will work to see what we can do to restore the previous functionality we had under Yosemite.
Please feel free to share your experiences regarding this issue, or any other issue you may have.
And most importantly, enjoy the music.
