Doesn't the device pointed to by alsa.physical_device reveal whether
it's a modem or an actual sound card? I don't have one of these modems,
so I can't test it from here.
However, I think it might make sense to create a new "audio" namespace
with a "class" property telling what kind of device it is. The above
method is alsa and pci specific which might currently be sufficient in
95% of cases, but in the future new buses may appear and other operating
systems might have different sound systems.
