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. --- Barry Duggan KV4FV On 7/1/20 4:53 PM, Cinaed Simson wrote:
Hi Barry - can you post the GRC file (no images please) for when the audio doesn't work correctly?-- Cinaed On 7/1/20 5:43 AM, Barry Duggan wrote: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.
