The Audiophile (and all envy24 cards, AFAIK) does only accept a
certain format directly. I don't know at the moment, which one it was,
but I doesn't have a samplerate of 44.1k for sure. That's why alsa has
the "default" plugin type, which converts on the fly to the hardware
specific format. So there's no need to use an asoundrc. Jack, I think,
can convert as well. At least I can start it like 

$ jackstart -R -d alsa -d hw -r 44100
...
loading driver ..
creating alsa driver ... hw|1024|2|44100|swmon
starting engine

on an AP just fine. 

$ jackstart -R -d alsa -r 44100

on the other hand uses the "default" plugin and warns:

  creating alsa driver ... default|1024|2|44100|swmon
  You appear to be using the ALSA software "plug" layer, probably
  a result of using the "default" ALSA device. This is less
  efficient than it could be. Consider using a ~/.asoundrc file
  to define a hardware audio device rather than using the plug layer
