Hey peeps,
So, I've been using jack with the onboard audio stuff in
my li'l cube (snd driver = snd-intel8x0) and that works.
And I've been recycling/parting-out older or broken systems
and found a PCI audio card with an ESS Maestro-1 chip, which
after some trial and error, discovered it needs to use the
'snd-es1968' snd driver (not snd-maestro3).
So I put the card in, reconfigured my audio, both cards are
seen, all the modules are loaded. and then I go to start
'JACK' and... well, each *one* works (although there is a
different problem with the Maestro-1 I'll save for later)
it seems to let me use *either* one or the other but not
both. What I really want is to be able to use the inputs
of both cards for multi-track recording. Really, I'm just
trying to get the stereo keyboard separated from the stereo
vocals, that's all. Seems like it should be no biggie,
but... not.
So, first off, is this possible? I mean there *should* be
a way, right? any clues for me before I go bangin' my head
on a wall? ;-)
Thanks in advance,
~Jos~

I found an entry for a .asoundrc file at this link:

So, I tried setting it up this way. I'm using exactly the script
shown at the link above. But it just ain't quite right. Here's
what I got in the messages window of 'qjackctl'

I have asked, just as you too are asking for a "dream come true!" Cheapo
cards for multiple IO's...
But alas...this is not to be! You can get both cards working in tandem
(of sorts) with the right ".asoundrc" file but they will not stay in
sync. I had 2 identical SBlive 5.1's and prayed constantly and fervently
to the great God of ALSA whom betrothed to us the .asoundrc miracle. For
40 days and 40 nights I fasted...but the "fuzzy wuzzies" in one or the
other card were NOT to be cast out. I was angry...then repentent.
I returned to use of 1 single cheap crap card....And it was good!

Too funny! i smiled deeply inside my mouth. ;-) But really, I'm

Multiple I/O, yes...
But alas...this is not to be! You can get both cards

That doesn't really matter. Mostly, I don't want to run my piano
through my mixer cuz it buzzes a bit and I get much better recording
if I run it directly into the input. And I don't want to keep
switching the 'puter input cables back and forth between the piano
and the finely mixed output of my vocal processor.
Also, most of the recording I do is in snippets. Bits and pieces
as they come to me. If I'm multitracking, I'm usually doing one
part at a time anyway, but if I'm just spark-flash composing, It'd
be nice to separate the piano track from the vocal/room ambiance
track. If there's an xrun, awwww, I'll just have to punch in or
realign or rehearse that part, but at least I'll have the idea captured.
For most of this kind of recording I use TimeMachine with a 3 minute
loop buffer.
I had 2 identical SBlive 5.1's and prayed
constantly and fervently
to the great God of ALSA whom betrothed to us the .asoundrc miracle.
For 40 days and 40 nights I fasted...but the "fuzzy wuzzies" in one
or the other card were NOT to be cast out.
I also had the idea of getting a couple of identical sound cards
and hacking them in hardware, just figuring out a way to handcuff
their clocks together. ;-) Anybody done such a mad mod yet?
I was angry...then repentent.
I returned to use of 1 single cheap crap card....And it was good!
I don't give up so easily. i can still use one or the other in the
setup as it is, so half my battle is won as far as separating the
inputs. I can select them in 'qjackctl' and restart JACK and that
seems to work. But now I'm down to one *or* the other, so that doesn't
solve the loop recording of snippets issue.
so, yeah, I think I understand the limitations pretty much. I'd
still like to try this for my own twisted reasons. So that request
for help with the ".asoundrc miracle" is still on the table. I'd be
happy if I can just select between them in JACK.
Okay, back to my head-banging....

You could try an run multiple jackd's as different users accessing your
hardware devices...
That way you always have all your sound played.

Well, that's because you cannot beat physics with software. If those
cards don't know the notion of "time" the other has then how should
they stay in sync? This is neither a problem of ALSA nor Jack, it's
simply a hardware issue. It's a bit like two people trying to play the
same saxophone at the same time: it won't fly.
You should get a real multichannel card or two cards that provide a
way to be synced to each other like the M-Audio Delta cards should do
(never tried) or the RME cards. Multichannel cards based on the IC1721
chips are really inexpensive nowadays.

I dont think the dedicated sync on the 44's and so on is supported under
linux - it requires some driver stuff. Wordclock will still work though.

It's my understanding that the 44 doesn't support sync, that you've
gotta go to the 66 or higher to get them in sync.
Even if there's no wordclock on the 66+ cards, you can still hit the
control in envy24control to force time sync to SPDIF in, and then hook
the cards up via SPDIF. But since the 44 has no SPDIF, I'm SOL on
that front.

I'm gonna restart this thread, because I'm pretty sure there's a real
answer lurking out there. :-)
To reiterate:
I realize that the idea of using two soundcards for multitrack
recording is fraught with sync problems. To be really clear,
I just don't care. I'm capturing snippets of this and that,
samples, room moises, etc. If there's a bit of drift, so what?
What I'm really after is track separation of different audio sources.
I understand the problems. I don't think they will seriously apply
to the somewhat non-standard usage I have in mind here.

Okay, this is what I need! Can somebody (Russell?) please post the
.asoundrc that makes this actually work? I've tried various bits for
".asoundrc" that I've found here and there online and I can't get
'qjackctl' to see the device, nor can I get 'jackd' to start manually
with the composite device.

Again, I'm not concerned with sync. I'm interested in *routing*.

I'd say it's more like to sax players playing with seemingly synced

This is in the works. I've narrowed it down to the M-Audio Delta 1010
or 1010LT. But that doesn't change *this* need. I'd still like to be
able to route my final mix (or my alsaplayer) either back through my
main (external) setup or just out throught the built-in soundcard to
the cheapo PC speakers. For that I'd still need JACK to see both cards.
Hope to hear some good ideas...

Go to the "Setup" screen in Qjackctl. Under the "Interface" box,
highlight the existing entry, be it HW:0 or "default" or whatever. Type
"multi" in its place and hit ok. Then try it...
The other was "ttable" which may have worked but I don't remember. Same

Okay, so this 'Interface' box, when you change it to something other
than HW:0 or HW:1, I believe it's gonna try to get the configuration
of that device from '.asoundrc'. 'ttable' is the same entry I got off
the ALSA web site, but I never got it to function. Do you still have
your '.asoundrc' file? It would probably be in your '/home/yourid'
directory or in '/root' if you start 'qjackctl' as root. I understand
it could also be in '/etc/asound.conf'.
Any other alsa configuration gurus wanna chime in and help us out here?

Okay, so this 'Interface' box, when you change it to something other
than HW:0 or HW:1, I believe it's gonna try to get the configuration
of that device from '.asoundrc'. 'ttable' is the same entry I got off
the ALSA web site, but I never got it to function. Do you still have
your '.asoundrc' file? It would probably be in your '/home/yourid'
directory or in '/root' if you start 'qjackctl' as root. I understand
it could also be in '/etc/asound.conf'.
Any other alsa configuration gurus wanna chime in and help us out here?

Go to the "Setup" screen in Qjackctl.
Under the "Interface" box,
highlight the existing entry, be it HW:0 or "default" or whatever. Type
"multi" in its place and hit ok. Then try it...
Okay, I tried
'multi'. Here's the error message:
creating alsa driver ... multi|multi|1024|2|48000|4|4|nomon|swmeter|-|32bit

The other was "ttable" which may have
worked but I don't remember. Same
procedure, just highlite the entry present and type the new one in.
And here's
what I get with 'ttable':
