If you don't have /dev/dsp* or /dev/sound/dsp* or ... (if find /dev
-name '*dsp*' gives nothing), make sure you load the ALSA OSS
compatibility modules with:
(and, if your card has a sequencer)
To use the sound card to record (i.e. with the audio out from your card
looped through the sound card line in). If you don't want to use that
cable, you'll have to load the appropriate audio driver for your card.
(IIRC, the OSS driver for bttv cards is deprecated, and the ALSA one is
more challenging to set up, but can be used if you get it working--with
the OSS compat modules mentioned above, though.)
