Lexicon Omega -- Works with ALSA, But NOT with Jack

sjfloat · December 14, 2010, 1:42am

I realize this isn’t a jackd forum, per se. If this is an inappropriate place to post this, hopefully some friendly soul with offer another suggestion.

Anyway, I just purchased a Lexicon Omega for use with my laptop. I am using a Delta 1010LT on my desktop and it works excellently. But I have been somewhat frustrated in my attempts to come up with something mobile. My most recent attempt is the Lexicon. Any advice would be appreciated.

Oddly, it works with ALSA (though there are no controls recognized) but not with JACK. The issue seems to be with the USB bus:

Add’l Info

I should add that it works fine on my desktop, similarly configured.

thanks

I had problems with my Lexicon Omega and Jack when there was another USB device (a mouse in my case) connected, so unfortunately I can only use the Omega when there’s no mouse connected - maybe try to give ‘exclusive USB power’ to your Omega…

sjfloat · December 14, 2010, 2:28pm

Further clarification; playback works with ALSA. Capture, not so much. This is on my Dell Studio 1749, where I had hoped to use it.

fkaluza · January 8, 2011, 9:02pm

i am using Lexicon Omega and it worked for me “out of the box” with ubuntu studio and Ardour and Jack of course. Play a while with options in JackRack. I know i did not help a lot, but hardware has to work with it.

Hi sjfloat,

What are the outputs of:
