* SAMPR_CAPS_ALL -> SAMPR_CAPS_ALL_48/96/192 * All targets claiming SAMPR_CAPS_ALL now get appropriate subset * No need to explicitly define HAVE_PLAY_FREQ * Rates that are a multiple of 44 or 48KHz can be used for playback Inspired by a patch by Roman Stolyarov, but substantially rewritten by myself.
