Yes, the names "SI7012", "default" and "default_1".

Aiming to have sound work. =8~)
[Old boring background story.
Two desktop PCs running Squeeze. Each machine has the mainboard
audio chipset, a USB C-Media headset and USB C-Media speakers.
On one system audio mostly works. On the other system, Skype and
Twoinkle work but never a sound from VLC or from Iceweasel.]
Seems that unambiguous identification of devices is a necessary
condition for sound functionality. The possibility of multiple
sound devices is acknowledged in the documentation now; so the
situation is improving.

Much more information than http://wiki.debian.org/SoundFAQ; which
has one less sentence now that a dead link is gone. Will study
and see what can be gleaned.
Incidentally, in the days of the ISA bus, "sound card" was appropriate
terminology. Today, referring to a little USB audio adapter or a chip
set on a system board as a "card" mokes no sense. Time to adopt a
realistic term. "Audio adapter" or "audio device"? One chunk of hardware
can have multiple "devices" making "audio device" too ambiguous.
"Audio adapter" isn't a good term for an onboard chipset. Any ideas
for a good term?
Thanks, ... Peter E.
