Hi all! I saw two posts about this earlier, which I think ended up being the result of a scripting error; I've included the link to both here:
https://github.com/pure-data/pure-data/issues/969
https://forum.pdpatchrepo.info/topic/12319/problems-using-pd-on-raspberry-pi

I am running Pure Data 0.51.4 on an RPI 3B+ (which I'm starting to think was my first mistake), and I am using the standard bc2835 Headphones hardware jack. The output works fine, and I can get sound running, but it will crash the patch after a minute and spit out this error:

I also wanted to mention that I had a regular RPI3 running Pure Data before this, and never ran into this issue, so I'm wondering if this is specific to the B+. I saw that the xrun recovery bug was found, but I don't think this error has been solved yet, so at the very least, just want to bump this issue! Thank you in advance for any help!
