Applied to 2.4.3-benh, it is still reporting back 48K.
>From the new /dev/sndstat it looks like it is trying to
resample, but if it is, it is doing a terrible job. But,
it falls so far behind and drops pitch enough, that
it still must not be resampling above 44.1K. I don't
see anything in the patches that would change the
old behavior, did Paulus' fix get lost?

Xine will resample just fine if the device would
simply respond back to the SNDCTL_DSP_SPEED that 44.1K
was set instead of 48K. There is no need to extend kernel
resampling to 48K, any apps broken in this regard are
going to be broke on many x86 platforms.

In case I've got the wrong level:
