Ok, been to his place tonight go dig deeper. We tried everything, and
eventually ended up with 4ms latency + ardour without xruns. For some
reason (maybe 64 bit ubuntu/natty) renoise didn't behave that well,
which threw me off, since it runs perfectly here.
What also confused me was that although PAM (limits.conf) seemed to be
configured correctly, renoise with realtime alsa kept on throwing the
"not able to use realtime threads" warning on startup. This never
happened to me before, for me it's always been a sure sign that
limits.conf was not configured correctly. Strange...
Anyways, he's gonna use ardour, so although puzzled I decided to leave
the renoise strangeness alone.
