The file is called spdif-in, but we abused it to show only sample rates
from various sources. Rectify it as far as possible (the FPGA doesn't
give us a lot of information).

FIXME: the polarity of "no copy" isn't clear - it could mean either "no
copyright asserted" or "no copies permitted". my attempts to test it
with an 0404b fed by an intel hda board went nowhere - the bit is never
set regardless of what i poke into the hda codec, and i don't know
whether the source or the card is to blame.
