Clark,
There's a couple of tricks to get it to work. Can you tell us a little
more info about your linux config? I have it setup to run with udev
which is a little bit harder to get working than if you don't.
Here's a good web page that describes this process:

Hi all,
Does anyone know how to successfully change audio in the middle of
execution? I've swapped out other blocks before, so I'm familiar with that.
Actually, I'm changing the guts connected to the audio, using the usual
flow graph stop, disconnect, connect blocks. I tried changing the guts
s thermometer setups in Home Depot, Target,
K-mart, and the like.
Or, were you looking for something a little faster?

Any more suggestions on spotting periodic content? (as below?)
Chiefly, can anyone think of something that I might be able to
definitely pick out within TVRX range?

There's probably a flag you can give it to overwrite.
Alternatively, you could edit the copy in your

things, be careful!

Yes, it's just looking for the profile python module which you probably
don't have installed.. I don't either, so I commented it out.
This change should probably be made in cvs, but you can do it yourself
if you are desperate.

There was some talk a few weeks back on creating a file format in which
there's a header storing info like the sample rate, capture freq,

sync_decimator handles the num in/out streams implicitly?)
