Description space88man 2021-06-17 01:26:24 UTC
Description of problem:
On Fedora 34, audacity does not list Jack as available Host even though
pipewire-jack-audio-connection-kit is installed

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install audacity(which pulls in portaudio), pipewire-jack-audio-connection-kit
2. Start Audacity
3. Edit -> Preferences -> Devices -> Host

Actual results:
Only ALSA is listed

Expected results:
Both ALSA and JACK listed

Additional info:
portaudio is picking up the correct Jack libraries

Comment 1 space88man 2021-06-17 01:28:04 UTC
In separate testing: Reaper(commercial software, uses Jack directly) does indeed see Jack via pipewire.

Comment 2 space88man 2021-06-18 00:00:53 UTC
On my system, portaudio alone does detect JACK:

// testpa.c
// gcc -o testpa testpa.c `pkg-config portaudio-2.0 --libs`

#include <portaudio.h>
#include <stdio.h>

int main(int argc, char** argv) {
	int i;
	PaHostApiIndex count;
	const PaHostApiInfo *phost;


	count = Pa_GetHostApiCount();

	printf("count = %d\n", count);

	for (i = 0; i < count; i++) {

		phost = Pa_GetHostApiInfo(i);
		printf("index=%d name=%s deviceCount=%d\n", i, phost->name, phost->deviceCount);

count = 3
index=0 name=ALSA deviceCount=12
index=1 name=OSS deviceCount=0
index=2 name=JACK Audio Connection Kit deviceCount=11
