Normally, the application connecting to ALSA looks at the port to find out
what sample rates it can do and adjusts accordingly. Any recording
application should lock to the interface rate with no resampleing. MP3s,
Oggs and other compressed/lossy formats do internal resampling/filtering
to match the desired output sampling rate anyway, but most of them are
44.1k to begin with. Wav files and flac and other no lossy formates are
the only ones where resampling is needed if they are not already 44.1k. In
general any wav files will be ones you recorded and already be the right sample
I think what I am saying is that for most cases the sample rate of your
audio IF doesn't matter. So adding resampling to everything doesn't make
sense... maybe try without first.

Playback a 48K wav file. if there are no extra clicks or pops it is fine.
