What's wrong with jack ?

[Ricardo Lameiro]

well, can you explain what do you mean with jack doesnt work out of the box?
i installed ubuntu studio setup jack and it worked. when i said setup jack,
i speak on setting the latency/frames/buffers/periods. and it worked on the
generic kernel with rt flag on jack, so maybe it doesnt work for you, but
form works.
