Hi Arnold
As you can see from my first post I suspected the interrupt issue to be the
matter here all along. I was just wondering why I could make it work in win
xp and not in ubuntu.
I will try if theres a BIOS update or something that makes it possible to
change interrupts
I was not aware that ffado has a readme-file. I will read that

I cant change my interrupts in BIOS unfortunately . But when I run Win xp
on this computer I can record four tracks simultaneously with 10ms
latency
or mix 8 tracks with plugins. So this should not
be a hardware issue.
And I have ffado together with nvidia graphics (without sharing interrupts)
working. So its not a software issue.
Now what?
Believe me: Sharing interrupts is still a bad problem in this century. At
least when you have to interrupt-heavy devices like firewire and graphics
share
the IRQ.
And its not that re-assuring that the other operating system works: There
you
have a special driver that works around the hardware quirks. And if you
look
at your sound-devices documentation, they will tell you a long list of
probably-not-working controllers and only a small list of working ones.
*A side-note: There is a reason the ffado-README
contains instructions
what
to
report in case of errors. Mostly a verbose log of jack. And the output of
ffado-diag...*
This last bit I dont understand..
What it says, is that ffado (the bit of software you use to make jackd talk
firewire) has an extensive README-file which explains what to do in case
you
need help or want to report a bug. Because most people (you too!) miss to
get
us all the information we devs need. And we feel that our spare-time is
better
spent hacking and fixing then telling people the same things over and over
again. Thats why you really should read the README-files of apps/libraries.
Have fun,
Arnold
PS: Your style of citations is broken and a strange mix of TOFU and
citations...
