Re: [linrad] CS5396

Hi Leif and all,

I just took a look at the eval board docs.

The bad news is that you can't get audio out via the
PC port; the digitized audio comes out in SPDIF
(or on a special connector).  This probably means
that you also need a normal sound card with 24-bit
SPDIF input capability (its A/D would not be used).

The good news is that with the above, you should
be able to run the eval board in stand-alone mode,
parallel port not connected, and not need any
additional software at all!
