I filed this as a bug on the alsa driver more than once. The problem is in the
Ensonic PCI card. Its firmware has the round-off error (obviously) and reports
44099. (This is not a pro-audio card. Unfortunately, my old dman has no alsa
support.)
This is a royal pain in the you-know-what! Some apps will simply not start up.
I can get Tapestry to run by specifying 44099 on its command line! Others,
like yours, may want to resample. Pain.
I believe that alsa's drivers should not report back absurd data. There is no
such animal as 44099. It should be changed to 44100.
