I have a microSD card, loaded with
shairplay-sync and Cirrus Logic Audio Card driver that is shared among two Pi's, one Model B rev 1.2 (I have one of those short format adapter modules that takes a microSD without sticking out of the Model B PCB) and one Pi 2 Model B.
shairplay-sync when compiled with
libsoxr is very CPU intensive (e.g. streaming Ariana Grande's Focus from Apple Music via an iPhone running iOS 9.3.3 will almost guarantee to stutter on a Model 1 without overclock as
libsoxr spikes the CPU, but nothing except network issues can affect the Pi 2)
It is not advisable to leave overclock settings as-is when moving from Pi 1 to Pi 2. How can I do this device-specific overclock settings?
