This issue was seen when attempting to use a Roland STUDIO-CAPTURE 16x10 Audio Interface to record audio in Ardour8 on NixOS. ~~What solved the issue (for at least that user)~~:

This issue was seen when attempting to use a Roland STUDIO-CAPTURE 16x10 Audio Interface to record audio in Ardour8 on NixOS. One possible solution:

~~- [https~~:~~//search.nixos.org/packages?channel=23~~.~~11&show=pavucontrol&from=0&size=50&sort=relevance&type=packages&query=pavucontrol Install pavucontrol]~~

* Install {{nixos:package|pavucontrol}}.

* Run {{ic|pavucontrol}}, navigate to the configuration tab, and set the Profile for STUDIO-CAPTURE (or your audio interface) to "Pro Audio".

- Run ~~<code>~~pavucontrol~~</code>~~, navigate to the configuration tab, and set the Profile for STUDIO-CAPTURE (or your audio interface) to "Pro Audio"

* Ensure the audio interface and Ardour are set to the same sample rate. Ardour8 will accept a configuration where its sample rate does not match the audio interface's sample rate, when using PipeWire, but will not actually be able to record audio unless they match. If you are unable to successfully activate a track's record button, this may be the issue.
