Here's what I get on a working system...
[d531][waltdnes][~] aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
default:CARD=Intel
HDA Intel, ALC888 Analog
Default Audio Device
sysdefault:CARD=Intel
HDA Intel, ALC888 Analog
Default Audio Device
front:CARD=Intel,DEV=0
HDA Intel, ALC888 Analog
Front speakers
...plus a bunch of others. Here's what I have in "make menuconfig" under
