Thanks. I'll send that stuff along this evening when I get back to that

As a process, I'm wondering how to best create all the files. What I did for
my current modules.conf stuff was to run alsaconf twice, once for the
AP2496, and once for the RME. I then attempted to combine the two by hand,
but I don't think it worked completely right. Both sets of modules are seen
by Linux as I see RME modules get loaded at boot time, but I can't seem to
send data out through it.

The AP2496 is working because I get sound out of it's audio ports.

However, inside of Ardour I'm unclear what I'm seeing as I see something
like 10 inputs and 12 outputs. (or the other way around) Since I know the
Hammerfall has 18 in's and out's, I'm certainly not seeing all of the RME,
but I didn't think the AP2496 should have that many in's and out's. I'll
have to go back and look at it's specs, but I thought it was 4 in and 4 out.

As for asound.state, I guess that has to be generated by running alsamixer
twice and constructing it by hand? I'm not clear. I think I could do that
this weekend. I'm anxious to get both cards going soon.

Again, thanks for being the pioneer and sharing the info.

nope. I have to set the levels for the pcm seperately. Also the quattro
doesn't have any alsamixer controls, only input/output level buttons on
the box.

Send me your modules.conf and I'll look at them for you. Funnily enough
mine are an almost carbon copy of the examples in the alsa-docs (I
maintain the ALSA website and constructed the new version of the online
docs so maybe that's not surprising).
