Hi ,
as far as i know "Creative SoundBlaster Airplay transmitter" is recognized by the kernel as a USB-DAC.
So it should be no problem to get it working with Rune Audio.
Do you think the raspberry can handle the HiFiBerry and the Creative at the same time?
This should be no problem for the
PI2 at all.
The only thing you should know is, that Rune Audio lets you enable only one output at a time.
So if you want to use them both at the same time, you have to tweak the system a bit.
See
