Re: [Discuss-gnuradio] trouble reexecuting a microphone audio source

[Thomas Early]

Thanks much Lou. That was my problem.

I thought I saw in a Ossmann sdr video that we were always suppose to use the 
big red x. I'll have to go back and watch again.

How do I stop a flow graph that only has an audio sink and no gui sink?

Did I miss a link to a "intro to grc" tutorial? It took me a while to figure 
out an audio sink max is 1.0.
