They occur in all downsampling algorithms, but they actually sound worse because the sample rates are so close together. Whatever audio quality you get from 48K vs. 44K is negligible, in my opinion, and won't offset the degradation from downsampling.

Btw. some cards generate a better sound quality at some sample rates,
regarding to their microchips, not regarding to Nyquist issues etc..

Hm? When using 32-bit float will there be 'loss' too? I (nearly) always
kept 96 KHz and 48 KHz recordings at those sample rates. But of cause,
burning an audio CD is interesting for me too, I just had many issues
with Linux audio, regarding to the sound quality. For professional
Studios as far as I remember we had a combination of Neve + Sony digital
recorders, that if I remember correctly, were at 48 KHz and perhaps
16-bit 'non-float', but to be honest, I never heard a CD. CDs and MP3s
always do sound disgusting. When I did jobs I usually had good luck and
could use analog equipment.
