device nodes are just files, you can give them the name you want (they
don't have to match the device's name). For example, the device node for
device com0 is /dev/tty00.
Also, not all device instance have a device node associated. For example,
network devices don't have a device node in /dev (they're accessible
via another namespace).
For this specific case, audio adapters are attached to the audio(4)
framework, and are acessible through the generic nodes /dev/audio* and
