You are better off using card name. If you plug in a USB audio or MIDI device then the hw index will change and may change on each boot. We considered a mechanism for fixing the hw index but decided the support overhead would be significant and found that using the card name was reliable and simple. Why are you not using the card name? Have you found an issue we need to know about?
Hi @riban,
Sorry for the delay. How can I retrieve the card name ? when I make a aplay -l I only have this infos :
root@zynthian:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0
BR,

In your example the JACK configuration would be: -d hw:Device.
I don’t understand, why the default AudioInjector selection doesn’t work. We are not using the number but the name
