These would be OSS devices.  To enable OSS emulation, load the
snd-pcm-oss module.  (This is done automatically by many distributions,
but it's possible that CentOS has decided this would not be appropriate
for an enterprise distribution.)

ALSA devices are in /dev/snd/; but to list capture devices, run
"arecord -l".
