Okay, I stand corrected - I've only tried to use once about a couple of
years ago.
If I can't open a GRC in email then I don't look at it.
I'm lazy.

Just as one has to do with getting a file from Github, you have to click
on the 'Raw' button before you copy the file with your text editor. Once
you do that, you will have the correct format.
For good measure, attached is the grc file.

There's nothing wrong with the flow graph Barry posted to pastbin. GNU

If I recall correctly, uploading a GRC file to pastbin.com and then
downloading it destroys the flow graph (the XML formatting) and reduces

Depending on what exactly you are doing, there may be another problem.
If you take the signal from an RF source, process and decimate
Hi Ryan,
Thank you for that information! That certainly is an essential piece to
be added to the wiki!
Probably I will create a new page for diagnosing audio problems. All
suggestions are welcome :)
Stay safe.

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.

Hi Barry,
I don't know too much about ALSA or PulseAudio, but I do know that the part of
the wiki that you cited is for setting up an ALSA source that grabs whatever is
playing through PulseAudio. It is *not* something that you can use for an audio

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
What does
aplay -l
indicate?
When using
hw:CARD=Generic,DEV=0
in gnuradio, try using numbers, for example,
hw:0,0
or
plughw:0,0
and see if it makes a difference.
Or try switching between sampling rates of 48000 and 44100.
