Hi,

I am able to record using alsa/jackd/ardour with the analog input from 
an AEB/4-I and plain pcm.rme9652 after tweaking /etc/asound.state by 
hand for getting the internal input from the AEB working. jackd/ardour 
works also very well with the PCI 128 only, even at period size 64. 
Now, I want to record with the RME and having analog playback through 
the PCI 128. Is this possible?

If yes, how to setup .asoundrc? I have been trying many combinations 
of multi and ttable settings, but honestly, I do not fully understand 
the syntax and semantics of alsa configurations.

I am using kernel and alsa-0.9.0 from a recent PlanetCCRMA 
distribution, which is really a piece of gold.
BTW, after fumbling around with my own kernel patching, I ended always 
with a complete freeze of ardour, when running jackd in realtime mode.

Here is, what aplay says:

[root at ardour root]# aplay -l

Pretty strange, since ardour does not complain, when trying to 
playback with the RME. Someone stated, that ardour ist writing 
directly to the hardware, and seems to have no problem, when there's 
nothing connected to the cards digital outputs. I also don't dare 
trying to understand, why there is one capture/playback device in 
/proc/card1/dev for the RME, while ardour reports 18.

Since I do not want to purchase another AEB/4-O analog output box, I 
would really like to know, how I could use my cheapo SoundBlaster.


Thanks for your help

Martin
