Holla! I have the same problem, running Pd 0.51-4, Raspberry pi 3 A+ (Should be up to date, installed and updated yesterday), using it's internal sound card. Patch includes [comport] that fetches data from an Arduino. Still investigating, but it seem to work for a couple of hours, then I get that same message, "alsa xrun recovery apparently failed". Gonna try another sound card.

for anyone else having this problem the solution is that you MUST declare a number of channels in the creation arguments for these objects, otherwise they don't create

Thanks!! This helped me ^^

Hi!
I ran into the same problem with multiple open socket connections, eventually crashing Pd. I read about multi-threading, but I don't really see how this solves the problem. What was your final solution? You still using TCP?

What happens at my end is that [netreceive] opens up a new connection every time it receives data. This is terrible, because eventually all the open connections will open up all the computer power and the computer will freeze.

Did you run in to this problem? How did you solve it?

Wow, just read through this whole thread, 4 yrs later. I relate to all the obstacles as I'm too building something that requires networking. When you think you've finally got it right, something else comes up hehe. I'm curious though, how did your project turn out?? Are there any photos/videos/recordings of your show?

@mattm Hi!
How did your installation work out? I'm attempting to do something similar, it downloads information from the internet that should then trigger stuff in Pd. I'm using processing/p5 with node, but, nothing really happens in Pd. Curious to know how you solved it!

9 year bump lol. This is super cool! Unfortunately your link does not longer work. Would you be able to upload it one more time?

Thanks
