The number after the slash in this conversation is 192kHz (sample rate), not 192kbps (compressed bitrate). The "44100Hz PCM audio" you see on your CDA/WAV/FLAC source, before lossy encoding, would be "192000Hz PCM audio" instead. Unlike bitrate, this number does not affect the "quality" of the sound (unless it's really low), but rather acts as a lowpass filter, dropping out the frequencies above 0.5x of it.
