No, roughly speaking if you have three sound cards in the system then
they are called: hw:0, hw:1, hw:2. However, you can use your asoundrc
file to rename them to more userfriendly names. THere is also a plugin
called "plughw" which helps out when the physical cards can't handle
certain formats, but otherwise sits there idly. For example my RME card
only support 32bit input. I need plughw to allow myth to send 16 bit
data. Basically if in doubt you should use plughw to just act as a go
between
Then for every real physical device you get a whole bunch of other
subdevices like spdif, multichannel surround, etc. There are quite a
few if you enumerate them!
I agree though that spdif is perhaps one of the more common devices we
might want to offer.
