I've built an OOT for some physical

However, when compiling a flowgraph in

it prints a warning message about no audio

insert a throttle.
Since my module actually paces the samples in
hardware, I don't
want a throttle. How can I supress the warning
message?
Looking through some GRC blocks, I've found two
tags:
<throttle>1</throttle>
and another is
<flags>throttle</flags>
Reading the documentation that discusses XML tags in the
block,
http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion#Creating-the-XML-Block-Definition
it doesn't mention these tags, or what they do. Is one of
these the
correct way to suppress the flowgraph compile warning?

I think the newer way is to use <flags>throttle</flags>
But for backwards compat, you can use
<throttle>1</throttle>
It's an indicator to GRC that this block provides a flow-regulated
data stream.
