when I run the flowgraph
it produces the errors I have listed earlier and then the flowgraph stops
and I am back in the QT GUI editorwhen I run the chmod command the first error goes away and the others remain
when I replace the audio source with a signal generator the flowgraph simulation runs
I need to install pulseaudio into my ubuntu system and then connect that to the audio block
So I believe I know my next steps,
I most likely will not be able to do these next steps for a couple of days

Hi Gary,
you seem to be misunderstanding me :)
Can you please tell me what does not work. That's not the same as telling us what errors
are printed. To make a comparison: you call a car mechanic. The mechanic asks
"What is wrong with your car?"
"Well, the two red LEDs in the dashboard are on"
"But what doesn't work?"
"the two red LEDs in the dashboard are on"
"Please tell me how your car actually doesn't function?"
"the two red LEDs in the dashboard: they are on"
See what I mean? The car mechanic would want to know whether your car still starts, or
drives, whether it behaves strangely when you accelerate or break or something, yet you're
only telling her or him that the lights are on.
Can you please tell me what does not work?
Best regards,
Marcus
