I downloaded but didn't yet build the Freebob package. They are
distributing their driver with a version of Jack - I think 100.1. They
have added their stuff under the jackd/drivers directory.

I didn't want to build it as it would probably start over wirting my
version of JAck. It looks like it would be good to get them integrated
into the mail Jack distribution.

I wonder if they have changed Jack to suit their needs. or is this
just easier for them than trying to embed their freebob driver into
the existing Jack direcories? Not sure it matters. It's just what they
are doing.

On a side note, I did a little bit of Wine testing with Jack. It seems
that Wine will produce audio using Jack 0.99 but will doesn't work
with 100.5.

It seems to be getting a bt messy:

Wine -> 0.99
Freebob -> 100.1
Ardour -> 100.5 (or something like that to get latency adjustments...)
My system -> 100.5

Maybe it's time for some sort of consolidation? It would be great to
get all of these things working on the same version.
Cheers,
Mark
