There seems to be quite a few versions of SB 16 out there, so it can get a
little confusing talking about them.
I have a SoundBlaster ViBRA16C PnP model CT4180 soundcard (as opposed to
the ViBRA16x (not sure if 'x' there is a metacharacter or not) discussed
in the kernel docs and such, mine supports an 8-bit and a 16-bit DMA
AFAICT (at least, the kernel doesn't complain, and the snd_dma16 option is
set to 5). The latest ALSA (0.4.1b) works wonderfully for me (potato,
self-compiled 2.2.12 kernel) in full-duplex mode.
If you want, i can post a rough outline of what i did, and the relavent
config files.

I've never encountered a catch. The manual states that you can only have
one session of simultaneous playback/recording at a time, playback and
recording must use the same [hardware] sample rate, and "you cannot add
reverberation when you play back Wave files", whatever that means.
Speaking of manuals, why does it claim the audio card _requires_ a VGA or
SVGA card?
