Got something. I used YaST to remove the EnsoniQ device and also to reload the Duo into modules.conf. Then after some futzing, got qjackctl to START with hw:1. Sounded like crap. I was seeing "Couldn't open hw:1 for 32bit samples trying 24bit instead."
jackd -d alsa -h
showed me how to make it do 16 bits, which is better for my purposes anyway.
jackd -t 500 -d alsa -d hw:1 -r 44100 -p 256 -n 16 -S & # the -S makes it do 16 bits.
Now it sounds great from the mic to the output, but I have a serious delay problem. Also can't record with
any gooey tools and can't quite figure out arecord yet. Keep reading, Bob.. don't go back to SONAR..

Thank you for the hints. There's some output below to chew on in case anyone's hungry. It looks OK to me but what do I know.. There may be an obvious problem there. I need to familiarize myself with modules.conf some more. SuSE wants me to use modules.conf.local for my own stuff so I may have conflicts there. I don't care about the order and I'd rather the ensoniq was out of the picture completely... I'm happy I can get sound out of the Duo at this point.
I'm packing for a trip to Las Vegas now, so this will wait for next week. thanks again

AND some Jack messages (loading the Ensoniq) btw, qjackctl won't let me get to any connections with the Ensoniq if the Duo is turned on!

-M-audio MidiSport 4x4 USB and M-audio Mobile Duo (USB)
So there are 2 ALSA devices with the same name.
They should have different names. What does /proc/asound/cards say?
Alsaplayer will play midi files but not CDs.
It assumes that the audio output of the CD drive is connected to the line input of the sound card.
The 2 USB devices give me 'no mixer elems found' I've read that
neither have a hardware audio mixer, so what do I use instead?
The MidiSport just sends MIDI data to other devices; it's the synthesizer that would have a volume control.
The Duo indeed doesn't have a volume control. You'd have to scale the audio data before sending it to the device. (Some future version of ALSA may be able to do this.)
It would seem that c 0 is the MIDI controller, c 1 is the
on-board, and c 2 is the USB Audio Duo (the one I want to use for
RoseGarden, Audacity, whatever..)
You can change the order with some entries in module.conf. For example, if your cards should be 0:Duo, 1:4x4, 2:onboard, use:
options snd-usb-audio index=0,1 pid=0x____,0x1021 options snd-ens1371 index=2
where ____ is the product ID of the Duo (see lsusb).
You can change the order by changing the index parameters.
