Just my 2 cents:
I've installed Openelec on my Raspi2, in order to use it as a mediacenter (via HDMI to my HT amplifier), with a "separate daemon" running Squeezelite (via USB DAC to stereo amplifier).
So I could use both same time, with no trouble with 1080p nor SqueezeboxServer streams!
:-)
Next step will be changing the USB DAC with a I2S DAC (I think Hifiberry DAC+).
