I'm pretty sure that I don't have JACK or Qjackctl on my upgraded fedora 34 system.  

Perhaps there is a way via some alsa subsystem approach to rename the sources and sinks.   Carla and Ardour identify my MOTU M4 as a surround sound type system, which is incorrect.

Do you know that devices name can né renamed at qjackctl, i'm just tweaking gere and found that, but I need to verify that these names continue after restarting. I send news here.

Something is happen with alsa-monitor.conf changes.


The only property that makes a visible change is the "audio.position"
parameter and it only effects the suffix of the device port names.

Changing the node.nick or device.nick doesn't seem to do anything as the
device names in Carla's patchbay, or the listed inputs and outputs
within Ardour are unchanged.


However, My MOTU M4 audio interface source has nodes: capture_FR,
capture_FL, capture_RR, capture_RL if I set:

audio.position         = "1,2,3,4"

and restart pipewire


Then those names change to: capture_1, capture_2, capture_3, capture_4


so the match portion within alsa-monitor.config appears to be working.
