Hello,
We are just ivestigating in this case at IEM.
So I think it make sense to make it public. and I made a Wiki-Page on pure-data.org
http://www.pure-data.org/Members/ritsch/latency/FrontPage
Please everyone just put your experiences in that so we can evaluate and make a HOW-TO-DO and WHAT-IS-POSSIBLE this year and maybe doing some programming to get better results.
Especially I will test the alsa and hdsp behavior and doing trying a low latency binding from pd to alsa direct (without jack).
But I just sometimes think the problems are somewhere else than on drivers.
