The logic appears incorrect. Based on the description, src_get_copy_limits() returns false when BOTH functions return 0, which means it returns true when at least one is non-zero (OR condition). However, for processing to be ready, you typically need BOTH a source with data AND a sink with space available (AND condition). The current OR condition would return true even when the sink is full but source has data, or when sink has space but source is empty.

Suggested change
return sink_get_free_frames(sinks[0]) || source_get_data_frames_available(sources[0]);
return sink_get_free_frames(sinks[0]) && source_get_data_frames_available(sources[0]);

in fact that was also my doubt about src_get_copy_limits() but @singalsu was sure, that it's correct...
