Hi Barry - the GRC isn't an image or binary file - it's a text based
XML file.
Send it as an attachment to your email.
If I recall correctly, uploading a GRC file to pastbin.com and then
downloading it destroys the flow graph (the XML formatting) and
reduces the GRC flowgraph to a stack of text from the blocks.
Try it.

Hi Cinaed,
The Pluto_NFM.grc is in https://pastebin.com/XZN0dK6x I have found
that reducing the buffer size on the Pluto almost eliminated the
audio underruns.
So what I am left with is needing to know what is wrong with the
procedure in
https://wiki.gnuradio.org/index.php/ALSAPulseAudio#Monitoring_the_output_of_your_system
I have been doing a lot of documentation updates and would like to
correct / improve that page.
Thanks for your help.

Hi Barry - can you post the GRC file (no images please) for when the
audio doesn't work correctly?

Hi Cinaed,
Thank you for your response. Yes, I have tried those and the
"hw:CARD=Generic,DEV=0" works well for most flowgraphs. I obtained
that from the 'aplay -L' command.
Let me reiterate my request: In exploring the audio problems, I
followed the instructions in
https://wiki.gnuradio.org/index.php/ALSAPulseAudio#Monitoring_the_output_of_your_system
and it gave the error I cited. So what I want to know is: Did I do
something wrong, or is the procedure not correct?
I need someone who is familiar with the ALSA and PulseAudio
software to look at this.
Thanks.
