Hi and thanks for the replies!
Actually, regarding latency, I'm running with 2.9ms right now (64 buffers 2
periods), and it's rock solid.
The problem is that soon there will be no more support for my rt kernel.
20ms. would be a huge downgrade for me, as tracking becomes a bit
problematic with such figures.
