Duplex mode not working with Lexicon Omega

[jeeshari]

Hello,

I am new to that linux music stuff. I bought a Lexicon Omega after checking the alsa wiki for supporting it.
Now I have the problem that I only could play OR record, so no duplex possible so far.

I used qjackctl to make the jackd settings. For the Omega three hardware addresses showed up:
1. hw1
2. hw1,0
3. hw1,1

where hw0,0 is input and hw0,1 is output. Jack is only starting if the default device is 2. OR 3.. If I mixed them in the setting as input and output device, jackd is not starting with a "broken pipe" messsage.

Any ideas?
thanks

Why do you wann use diferent cards for input and output?
just choose the omega in "interface" and let the rest "default"

What says the terminal if you type:

aplay - l

?

Thanks AutoStatic for the hint, but I already read this post several times.
My problem is, that input and output are working but not at the same time. I dunno if merging the two hardware addresses makes any sense here, but I will give it a try.

@Capoeira: I dont want to use two different cards, in my example hw1 is the Omega with hw1,1 for the output and hw1,0 for the input.

I will post the aplay and arecord info as I am at home.

thanks !

Hello jeeshari, no need to merge anything as osterchrisi already found out that it doesn't work.

[jeeshari]

Mh, so no need to waste more time on this? I guess, I will send it back and purchase a m-audio fast track pro.
thanks anyway!

Fast Track Pro doesn't work ootb either afaik.
iirc the Lexicon could work if you'd set a fixed number of inputs and outputs (4 I think).

[jeeshari]

okay, with a fixed input of 2 the Omega is working in duplex mode. Anyway, 2 more a missing.

the output of aply -l

Code: Select all

Maybe this helps a bit: http://ardour.org/node/1449#comment-9487
Doesn't say anything about duplex though. I'm not familiar with this card, would love to get my hands on one though just to get it going
