No audio input ports

[cbix]

clap-host 1.0.2 on Linux + PipeWire (jack/alsa/pulse) doesn't provide any way to connect audio inputs, only outputs are created. This is fine for synthesizer/instrument plugins but not for effects.

Couldn't test latest master since that doesn't build at all.

[cbix]

On 1.0.3 with rtaudio 6 no audio ports are created at all and this error printed:

RtApi::openStream: output device ID is invalid.

Still couldn't build latest master:

Ping @abique

[digitalsignalperson]

I'm on arch linux. I get the same RtApi::getDeviceInfo: deviceId argument not found.

in this function

void AudioSettingsWidget::updateDeviceList() {
   _deviceChooser->clear();

   auto deviceCount = _audio->getDeviceCount();
   bool deviceFound = false;

   // Populate the choices
   for (int i = 0; i < deviceCount; ++i) {
      auto deviceInfo = _audio->getDeviceInfo(i);

For auto deviceCount = _audio->getDeviceCount(); I see my device count of 6

But for each auto deviceInfo = _audio->getDeviceInfo(i);
it prints RtApi::getDeviceInfo: deviceId argument not found.

and the resulting deviceInfo struct is empty / zero initialized

[digitalsignalperson]

This was a breaking change in RtAudio where the argument in getDeviceInfo(i) is no longer an index, but a device id.

The fix can be like

auto deviceIds = _audio->getDeviceIds();
for (int i : deviceIds) {

[cbix]

@digitalsignalperson thanks for your input (pun intended), for me this fixes the device selection but still no input ports show up in JACK :(
