When starting Pd, audio devices are detected fine with ALSA:

$ ./bin/pd -alsa -listdev
audio input devices:
1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
audio output devices:
1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
API number 1

no MIDI input devices found
no MIDI output devices found
priority 8 scheduling failed.
^CPd: signal 2

Yet with PortAudio, no devices are found:

$ ./bin/pd -pa -listdev
no audio input devices found
no audio output devices found
API number 4

no MIDI input devices found
no MIDI output devices found
priority 8 scheduling failed.
^CPd: signal 2

This happens in Pd 0.50.2 on Fedora 31 x86_64.

not for me:

$ pd -pa -listdev
[...]
audio input devices:
1. (0) jack
2. (0) pulse
3. (0) default
4. (2) system
5. (2) PulseAudio JACK Sink
audio output devices:
1. (0) HDA Intel PCH: HDMI 0 (hw:0,3)
2. (0) HDA Intel PCH: HDMI 1 (hw:0,7)
3. (0) HDA Intel PCH: HDMI 2 (hw:0,8)
4. (0) HDA Intel PCH: HDMI 3 (hw:0,9)
5. (0) HDA Intel PCH: HDMI 4 (hw:0,10)
6. (0) hdmi
7. (0) jack
8. (0) pulse
9. (0) default
10. (2) system
11. (2) PulseAudio JACK Source
API number 4

note that i'm using the system-provided PortAudio, rather than the one that ships with Pd, as the latter never ever worked for me on my Debian systems. (also I never use PortAudio at all, if not for testing it for other people :-) using JACK is just superior on a pro-audio environment)

I still get the same result, even when I compile with ./configure --enable-jack --without-local-portaudio. I'll just use Jack but this may or may not still be considered a bug of some sorts.
