[Bug 46998] USB sound devices get index of 0 instead of PCI/onboard sound

[fubarbundy]

Public bug reported:

To reproduce: on a machine with a working sound card at index 0 (listed
in gnome-volume-control under file/change device as '0: xxxx', plug in a
USB sound device (especially something like a microphone, webcam etc.)
Reboot.

Result: USB device steals index 0 and ALSA assigns it default status.
Any other programs using /dev/dsp break.

Expected result: PCI and other internal devices get assigned lowest
indexes first, ensuring they have a dependable device node. USB devices
then get given higher indexes/nodes as they are less permanent.

** Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed
