OK. I did "aplay -L" to list all soundcards, then "aplay -D soundcard
file.wav" to test each soundcard, and these work:
default:CARD=Live
front:CARD=Live,DEV=0
surround41:CARD=Live,DEV=0
Odd that the one called "default" works when specified, but the system's
broken by default.
I looked at /proc/asound/cards and noted that my sound card (a SB Live!,
whose support module is *emu10k1*ko) wasn't default, something called "USB
Audio" was. (A few days earlier, I had tried and failed to get sound
through my turntable's USB connection, and it was still connected.) I
couldn't figure out how to set the default there. Bringing ALSA down with
/etc/init.d/alsa-utils didn't allow me to rmmod snd_usb_audio, so the only
way I knew to do what I wanted was to reboot, and unplug the &$%@ USB
turntable so usb-audio didn't get loaded.
Yay, sound.
