Hi all, 

as requested, my configuration of the el-cheapo hack 
I bought 2 sweex 4.1 sound cards (netherlands, 10 euro each) 
which are CMI8738 chips, sweex model SC011

they contain 1 chrystal with 2 feet. can't miss it.  

I soldered a microphone wire into the two empty holes on the 
crystal-stripped card, and soldered the middle wire onto the 
crystal equipped card. this is different from the tutorial, but works.

after that, I tested with baudline, and both cards (still) worked.

I'm developing a robot sonar direction finder, 
and with sonar, more channels are better. 

Thanks for the el-cheapo hack ! 

(now back to the mess that is called Alsa/Jack. how the <bleep>
 can I query/see/confirm that those self made aliases set up in the
 ~/.asoundrc are actually processed and available ? Jack does not 
seem to see them, it sees 2 capture devices where I am endowed with 
no less than 4 soundcards, which *are* known to the system)
