AFAIK the chip (at least that of the new ipods) supports quite everything
up to 96kHz, so it should be a driver issue. Also, probably the driver
won't support recording, that the new ipods do.

The documentation for the Wolfson WM8721 (old ipods) is at
http://www.wolfsonmicro.com/products/digital_audio/dacs/WM8721/ , for the
WM8731 (new ipods) at
http://www.wolfsonmicro.com/products/digital_audio/codecs/WM8731/ .
