14 char Open Sound System (OSS)
0 = /dev/mixer Mixer control
1 = /dev/sequencer Audio sequencer
2 = /dev/midi00 First MIDI port
3 = /dev/dsp Digital audio
4 = /dev/audio Sun-compatible digital audio
So it's /dev/dsp where your grep should have been catted to.
(Sun-audio is probably some uLaw device and there's no support for this
in current SB16 implementation)

That's something to be expected.

0xce is ADC command, ADC is not supported
