I have problems using PD on a Raspberry Pi 3B+ with Raspbian. I downloaded the newest version of Raspbian to a SD card and installed PD using
sudo apt install puredata.
When I open a patch from the help files it is working fine, but when I open a patch that I prepared earlier, even though it opens up, when I turn on the DSP it crashes. In the console it says:
restart alsa output
alsa xrun recovery apparently failed
pd: pcm.c:1168: snd_pcm_prepare: Assertion 'pcm' failed.
Pd: signal 6
And while opening PD the console writes: priority 8 scheduling failed.
In the PD window it says: priority 6 scheduling failed: running at normal priority.
I don't know if that might be important, too.
Any ideas what might cause PD to crash and what the console messages mean`?
