No, 15 kHz is not "very minimum", it's impossible. Your console will contain information that the UHD picked a different, higher, sampling rate.
Your "I picked 15 kS/s to get a clear audio file" doesn't make much sense; this is not how digital communications work! I'm afraid you'll have to be way more careful when designing an RF transceiver. Maybe you'd want to read up on complex baseband, constellations, pulse shaping, symbol synchronization and resamplers, so that you understand what's happening in your flow graph.
