No CD player would put out 3 Vrms - they must mean 3 V peak to peak. To answer your question, the output of a CD player is continously variable from 0v to its max voltage output. As a related point interest, every line level preamp, I've ever seen, has no difference between the AUX, Tape In, CD etc.
So, for example, an audio signal with a bandwidth of 20 kHz must be sampled at least at 40 kHz to avoid aliasing. In audio CD's, the sampling rate is 44.1 kHz, which is about 10% higher than the Nyquist Sampling Rate to allow cheaper reconstruction filters to be used.
