The action in Yast of setting card 1 as the primary DOES change its number. The primary card automatically becomes card 0 and stops working. The old card 0 becomes card 1 and starts working.
aplay -L with the Lynx card as primary gives:
[INDENT]null
Discard all samples (playback) or generate zero samples (capture)
