changed alsaloop from autosample method selection to input. This method was causing high CPU when paused and in some other states. So far the Nexus 5 and Samsung S4 test devices seem to be ok with this setting. Since AOA2 is universal, this should be ok for all devices. People will likely use different output devices so doing it on the input is preferred.

added Samsung S4 to udev rules. play/pause and track skipping tested ok.
made an oops
