This also has been discussed before.
You must use an application such as mplayer (as you said) to convert
sample rates, as the kernel does not do it.
Here is an mplayer config that I made which does a nice quality resample:
~/.mplayer/config
srate=44100
framedrop=1
fs=1
af-adv=force=1
vf=pp=lb
The lines you are interested in are srate= and af-adv=. Without af-adv
I experienced distortion.
Hope this helps.
Best Regards
Edd
