It appears there are two standards :P
I have spent the last few days just looking at files and sample rates. The
majority of them (straight audio and video, eg. youtube) are 44.1k.
However, The consumer PC audio hardware standard (according to Intel and
MS) is 48K. There are some AC97 audio interfaces where anything but 48K is
broken, the SB Live! being the best example. Where recorded left and right
tracks in 44.1k may be different lengths and out of sync. The
manufacture's "fix" was use 48K.
However, There are little if any AC97 IFs still in use and the Intel HDA
spec while still standardized on 48K has fixed the 44.1k part of the spec
so that at least it works :)
I had a friend who recorded a Christmas production with two mics into an
SB Live! The two tracks were several seconds different in length.
Hopefully most of these cards are long since replaced. The earlier es1370
based cards were one of the best consumer cards at the time. (any rate
