Maybe that's specifically an ICE1712 problem? I don't know of any
problems with my RME cards. I certainly see all the Alsa ports the
card has to offer in QJC. (26 in/26 out) I cannot imagine any
performance issues on my card since I run it under Jack all day long.
No xruns to speak of, etc. Everything seems cool.
That said the major usage problem I have with Alsa (not with Ardour)
is that it's sort of brain dead about real life. We want Ardour
running and so we have Jack turned on. At the same time we're not
recording, etc., 100% of the time. We're doing email, browsing, etc. I
need to be able to look at video and hear audio while my Ardour
session is running but not active. (Hope that's clear. If not come to
the meeting on the 12th.) ;-) !! ;-) Anyway, I have continually hoped
for info on how to make Mozilla/Firefox really work at the same time
I've got Ardour open.
