No, I hadn't, but I just did now.  I ran the following:

[root at elise root]# sox -w -r 32000 -t ossdsp /dev/dsp2 -t ossdsp /dev/dsp | 
esdcat -r 32000

and got the following output, in addition to something that wasn't quite 
static, but definately "noise" coming from my stereo speqakers:

opening socket, format = 0x00001021 at 32000 Hz

So I *think* /dev/dsp2 is working right.

I did try /dev/dsp1, and mencoder just "hangs"... i.e., instead of the 'Pos:' 
counter counting up, it stayed at '0.0s'.  HOWEVER, when I removed the whole 
':adevice=/dev/dsp2:forceaudio:forcechan=2' portion, I actually was recording 
sound!  Although it gets recorded with a bit of a "whine", but that's just 
likely the soundcard (it's one of those SiS mainboard built-in jobbies that 
uses the 'trident' module), or is it because the default device 
('/dev/dsp1'?) is analogue, as opposed to digital?  Or will that make a 

Anyway, that's getting slightly off-topic, so I'll leave my questions at 
those, and thanks for your help!
