My speculation is that the kernel driver for the chip, or its
implementation on the i.MX25, may not have been mature back in 2008/9.
The kernel patches (in here:
https://github.com/Logitech/squeezeos/tree/public/7.8/src/imx25/patches/logitech)
have Logitech's moniker on them. As implemented, it seems to advertise
only 44100Hz and 48000Hz sample rates.

Also note that the Radio's ALSA Crossover and equalizer plugin (babydsp)
is only designed to operate at one rate (44100Hz). The filter
specifications would be 'a bit off' for a 48000Hz sample rate stream,
but probably not noticeably so.

I have observed that the ALSA rate conversion plugin will downsample
both these rates to 48000Hz before handing over to the hardware.

One reason why I, personally, have no interest in high sample rate
tracks. :)
