Agreed. According to Peter Todd, in the Linux Journal, 96 kHz is
possible by switching to Double Speed mode:

Switching between SingleSpeed and DoubleSpeed
Mode—Using 96kHz
As mentioned above, all software using the HDSP must be closed before switching between
SingleSpeed and DoubleSpeed mode. But normally,
software sets the sample rate. So
what now? Well, there is a setting
related to the AutoSync functionality (more on that later) that can do
the job, Sample Clock Source. I won't explain exactly how it works just
yet, but basically, by setting the internal clock to different
frequencies, the card automatically switches modes. For instance, to
switch to DoubleSpeed mode run:
amixer -c 1 cset numid=11 6
To switch back to SingleSpeed mode run:
amixer -c 1 cset numid=11 3
In both cases, don't forget to make sure that no application currently is using the
sound card.
