OK, nothing in /etc/modprobe.d (this was a clean minimal installation) so I made a file, put in that line and rebooted. All OK now, speaker-test and alsamixer are working, I'll get around to loading my sound player software when I have more time. Thank you again. I presume this is a minor bug, a USB card really should not be forced not to be card 0 if there is no other candidate. -- Joe
