RuneAudio does not play some radio stations. I've had excellent success streaming hi-res audio (24-96/192KHz and DSD64) to a Raspberry Pi 2 B with a Dragonfly v1.2 and iFi nano iDSD using piCorePlayer and SqueezePlug. I got so caught up in this activity that I had to ask write my paper on
https://writemypapers4me.net/. Initially, I experienced dropouts with audio files above 96KHz, but was able to eliminate the problem by increasing the buffer size (Buffer size settings=60000:200000). For the server, I'm using Logitech Media Server v7.9.0 on OSX 10.10.x.
