Oh, then I my first thought was wrong. I thought you simply wanted to
rename the devices because of some obscure reason >:-)

Then you will have to Google by "vlc linux sound device" or something in
that shape :-P

Well, yes. When you have different sound cards/devices you have to:
1/ Choose the system's default one.
2/ Change the device for every application where you want to use a
different card other than the default.
IIRC, this has been discussed several times here, in this mailing list.
There's a good doc about it here:
How can I change the default ALSA device?

Well, those modern USB audio devices (like the headsets) can be more
powerful than most of the Intel HDA embedded chipsets :-P

I think it's still needed to differentiate between the hardware
(physical) device (USB external card, pci card, USB headset...) and the
used chipset so the old nomenclature is fine with me (sound card/sound
device and sound card/device chipset).
