Hi there,

I switched to Ubuntu Studio 24.04.1 LTS and installed it from scratch. And I installed Purr Data that I was using with Ubuntu Studio 22.10 before. Therefore, I added the aggraef:/purr-data-jgu repository and installed purr-data via apt as described for xUbuntu 24.04 here:

https://software.opensuse.org/download/package?package=purr-data&project=home%3Aaggraef%3Apurr-data-jgu

Unfortunately, I'm facing the following two problems:

1.) Purr Data starts up very slowly and the GUI is a kind of frozen for few minutes until the error message "error: audio I/O stuck... closing audio" is output. Then the GUI is working again, i.e. I can change slider values, for instance. This issue also occurs if there is an audio interface attached with an active usb audio connection via Pipewire. Purr Data is not listed in the Carla patchbay.
2.) There is no menu. Please find attached a screenshot. Respectively, I cannot change or have a look at the audio settings. The cat icon only lists window related entries for e.g. minimizing the window.

Any ideas how to solve these issues? I couldn't find any posts regarding this.

Thank you in advance!

I don't know at what state Purr-Data is (maintained, developed, abandoned), but you can give PlugData a try instead. It is actively developed, and should probably include what you need. Although, Pd-vanilla should also cover your needs, as almost all externals from the Pd-extended era are present in its repositories, installable through Help->Find externals.

I prefer Purr Data since it is much more attractive visually and since it can much better handle my 4k display. PlugData is really interesting, but adds too much visual overhead for my purposes.

Purr Data seems to be in active development and I reported the issues to its Github repository. I hope that there is a solution or that it'll get fixed.

I found a workaround given on the Purr Data Github page and described in the Purr Data installation instructions, see https://github.com/agraef/purr-data/wiki/Installation. I seems to solve both issues.
