Please test the 44.1kHz -> 48kHz conversion with the following file:

 http://invisible.yi.org/~jmcneill/misc/swoop.wav

My ESS Allegro-1 uses a DSP image that does sample-rate conversion up to
48kHz, and it does a pretty poor job of it. The poor job is evident when
listening to that .wav file. After playing it back with 'audioplay', try
'audioplay -f -s 48000 swoop.wav' and compare the two.
