Hi, I am very rusty with Pd and trying to get something to work that was working a few years ago, but I am having to rebuild it.

Hardware: Raspberry Pi 4+ with original RPi 7 inch touch screen
OS: 'Bookworm' 32 bit ('Raspbian 12')
Running latest version of purr-data downloaded from Open Build Service for this OS.
I want sound through the headphone socket.

Without running any patches I get error 'error: audio I/O stuck... closing audio'

Under preferences I have ALSA API and select headphone output.

I'm stuck!

Help would be greatly appreciated!

Thank you

Did you try vanilla? It's very easy to install externals through Tools -> Find externals (or Help -> Find externals on older Pd versions). You can install it with apt-get or compile from source (which is an easy process). It's more likely to work, I guess.

Thanks. No, I can give that a try. Would I have to uninstall Purr-data first?

I think I use a few non-vanilla libraries, but I guess I can quickly identify them.

I don't think Purr-data's installation will interfere with Pd, so you shouldn't need to uninstall it.
If you have externals, as soon as you open your patch in vanilla, you'll get one error message per object that couldn't be created.
