Hi
A friend of mine has just installed ubuntu with a little phone support
from me. The changes we did were:
1) Add him to the audio group /etc/udev/rules.d/40-permissions.rules
2) Add the following to
KERNEL=="raw1394", GROUP="audio"
KERNEL=="dv1394*", GROUP="audio"
KERNEL=="video1394*", GROUP="audio"
3) Install a realtime kernel
However he still reports that jack exits after about 10s with buffersize
128 and he get's lots of xruns on larger buffer settings (I think even
on 1024).
This surprises me, since I run standard ubuntu (recently installed the
realtime kernel, though) with no xruns on buffersize 128 with an FA66.
Is there anything I forgot in my over-the-phone instructions? Other
ideas on how to narrow this down?
NB: I don't his computer, but according to him, it's an "old laptop"...

Why dot you let him install AV Linux, that will run out of the box ?
http://www.bandshed.net/AVLinux.html
or /and can be checked before as Live Dvd to see if anything work like
suspected.

1) Because I'm gonna have to help him alot, and I don't know AV linux.
2) Because I refuse to believe that it's something wrong with ubuntu, at
least that's what my experience (with arch and debian) tells me.
3) Because I refuse to let
this-version-of-this-distro-runs-out-of-the-box-on-this-hardware dictate
choice of distro. What if the next update runs bad, should he change
distro, then? Not a good start for a newbie like him.

If you run AVLinux and things "just work"... then it's a
probably a simple configuration issue. If they don't...
then you may be messing with something deeper (like lack of
a USB 2.0 controller or something).
In a similar way, when things "just work" with a Knoppix
CD... but they don't work with my installed OS -- that was
helpful information to me.
BTW, Does Lucid have a RT kernel? I thought they were using
the .32 kernel (for which there is no RT patch).
Peace,
Gabriel

Ok so you mean as a test. That might be a possibility. I think I should
sit next to him, to make that happen, though...

It's debian/testing based

Yes, sure , it's a better start when things don't work and you have to
fiddle around for day's to get your configuration right. :-)
And on debian/testing you don't need to be to angry for a update.
But it was only a suggestion, not a dictate. ;-)
If you prefer a other choice, it's well.
All very good reasons, BUT...

At least, I mean both, I personally like the possibility to run a Live
CD/Dvd from a distro before I install it. This way I can see if it is
worth. But I mean also what you mention Gabriel, run it as check.
Thanks for clarification help.
