It turns out I can only select audio devices which are not set to "Pro Audio" in Pipewire. I assume this is because OSM uses its own static linked ALSA libraries which want to access the audio devices directly. This however is blocked when a device is in Pro Audio mode. Modern Linux systems have replaced ALSA libs by compatible libs that interact with Pipewire directly.
Audio devices in Pro Audio mode is however what you want with Pipewire because the audio system then will avoid most or all processing of audio between the interface and the applications – this is what I'd expect for a measuring tool.
This may be related to #115.
