Hi list,

I recently bought a focusrite Scarlett 2i2.

I already had a look at http://linuxmusicians.com/viewtopic.php?f=27&t=10055&start=30
and first asked there, without success.
So I am reposting it here, with hope that someone has ideas how to get it running.


Capturing works out of the box. But I did not get the playback running.


Here my Systeminfo:

jack only runs at 48kHz with 512 Frames and higher.
Non realtime, no memory restriction, Duplex


I tested the playback with Pulseaudio and Jack, neighter worked.

Does anyone have a clue, what I am missing?
