[MPlayer-users] VIA82xx ALSA driver, mp 09.0rc7, noise using FP resampling

I have an Epia 800 board, running the ALSA via82xx sound driver. For 
some reason this only outputs digital audio at 48000, which is fine with 
sources sampled at theat rate, but mostly I'm playing MP3s which are at 
44100. Leaving the upsampling to the chipset, I get the same high-end 
distortion reported by others. Using mplayer -af resample=48000:0:1 I 
get much better output, but I would rather use the floating point 
resampler (replacing the '1' above with a '2'. However if I do this, I 
get good quality audio, but with a very high level of 'hiss' behind the 
signal, probably only 10dbB down or so from the music. I don't get this 
with the integer-based resampling -- is there anything I should be 
looking at, is this likely to be driver-related, or can I log this one 
as a bug?
