You're absolutely correct.  I deleted them, then ran as user which created 
newly owned ones, but this is what jackd -v -d alsa returns:

registered builtin port type 32 bit float mono audio

required capabilities not available??? Is this because I'm not using the 
real low-latency kernel?  Even though it says 'waiting for signals', when 
I try to start something with a jack output, it says it can't find it.

I may be confused, but, I don't have anything 'surround' related.  It's a 
new stock box, which only has stereo in/out jacks, so I can't imagine 
there is any hard or software that would be telling alsa to do this stuff.  
There are, however, duplicated audio in and mic ports (one in back and one in 
front) but it's a real cheap box, so I assumed that were hardwired into 
the same input/ A/D converter.

Thanks for the help, sorry if I'm missing something stupid!
