That's cool but I still need a switcher. I found a 4-port one here that
looks promising, esp. because it has RS-232 control support for changing
inputs. Hook that up in front of an RME FireFace 800 and now we're
talking. :-)
Then you have a complete mixer surface in your Mac. AES/EBU is compatible
with S/PDIF.
Going back to a previous question, yes the DD sync word is two valid
16-bit samples but the DD over SPDIF specification recommends searching
for 4 leading zeros first to reduce the likelihood of collision even
further. In practice (so far), I have not found the extended sync word
necessary.
Nice tip! They are obviously assuming that when the signal changes from PCM
to DD there will be a short silence before DD starts. Sounds reasonable.
When I searched for only sync word, in a normal PCM stream, I got match now
and then, about one in 1 minute on average. At least during that broadcast.
