Okay, that was a braino - I misremembered what sndstat displays...

Anyway, /dev/dsp* are the OSS device-nodes for recording and playback (and 
freebsd's newpcm is OSS compatible), so that is still correct. Everybody has 
the /dev/dsp device nodes (and nobody has /dev/pcm).

Not sure what you're saying here, I was referring to mixer devices. If you 
type 'mixer' in your shell, you'll get output similar to this:

[lofi at kiste]:1:~ > mixer
Mixer vol      is currently set to  75:75
Mixer pcm      is currently set to 100:100
Mixer speaker  is currently set to  75:75
Mixer line     is currently set to   0:0
Mixer mic      is currently set to   0:0
Mixer cd       is currently set to  75:75
Mixer rec      is currently set to  11:11
Mixer ogain    is currently set to  50:50
Mixer line1    is currently set to  75:75
Mixer phin     is currently set to   0:0
Mixer phout    is currently set to   0:0
Mixer video    is currently set to  75:75
Recording source: line

As you can see, in this example there are two line-ins (line and line1). The 
first one is selected as the recording source (and it translates to a Line-In 
minijack input on my onboard sound). The rec mixer device controls the the 
record level of the selected recording source.
