No I didn't...but thanks for the idea.

I think I have a handle on this. And mush thanks to Mr Depner for
helping me out with an .asoundrc question.

To provide the solution after all my bleating:

I had been using the "default" alsa setting in Qjackctl. I had this
nagging feeling that setting up an .asoundrc as I have always done in
the past would resolve this, or at least help. I read somewhere that the
"default" setting is not as efficient? Anyway, no amount of googling
would give me enough info for an .asounrc config for the 8 analgue I/O's
(or so it seemed to my sublime ignorance). I tried several different
configs and each way I entered them thru Qjackctl would not provide

Finally, I read Jan's how to again and looking at his script and knowing
he is also using the 1010, I saw he had the generic .asoundrc from the
Alsa site. I e-mailed him asking how and if, in fact, he gets the 8
I/O's showing in the Connect pannel of Qjackctl. He was kind enough to
indulge me and said that he is now using the .asoundrc that is listed
for a "hoontech" card with the Envy24 chip on the bottom of the Envy24
pages in the Alsa site Details and docs. So I figured I'd plug it in and

I fired up Qjackctl again and tried the usual "hw:0" and "default"
settings. None would connect at first. Then I tried setting the
"channels" widgets to "0" where I had been setting them to either 2 or
8. I set to hw:0 and ........WAHLAA! Finally!!! This .asoundrc actually
sets up for 12 ins and 10 outs. It's including the digital I/O's as well
for the needs of whomever wrote this particular one. And in point of
fact the CPU usage shown is lower using this and less call backs than
the "default" setting.

Been farting around with it for several hours now and not one "Snap,
crackle nor pop!" Been using the 2.6.7 kernel with all the realtime
goodies to see if it is better now I have a good configuration for my
card. It seems to be...

So, it seems I'm up. (Throws salt over shoulder) I have a rehearsal
tomorrow night so it will get a work out.

Thanks for the replies and hints. And Thanks Jan for pointing me where
I'd already been but didn't know I was there and removing all doubt! :)
