[02:09] <ronj> ailo_, I'm doing some -lowlatency testing, did you do some?
[02:15] <holstein> hey ronj
[02:15] <holstein> i usually get my presonus firepod going
[02:15] <holstein> start ardour
[02:16] <holstein> and route my 8 inputs from the firepod to 8 tracks in ardour
[02:16] <holstein> let it roll record for an hour or so
[02:34] <ronj> holstein, hola
[02:34] <ronj> yup
[02:34] <ronj> results yet?
[02:34] <holstein> o/
[02:35] <holstein> yeah, i can do that with no xruns at around 1.7ms latency
[02:35] <ronj> holstein, by the way I'm preparing a mail. why the hell these doubts around lowlatency?!
[02:35] <holstein> with a -realtime kernel
[02:35] <holstein> not near that without though
[02:35] <ronj> everybody seemed to agree it is the path to follow
[02:35] <holstein> with the -lowlatency kernel
[02:35] <holstein> BUT
[02:35] <ronj> and now Alessio comes back on this
[02:35] <ronj> did I miss something?
[02:35] <holstein> i think something about firewire still needs -realtime
[02:35] <ronj> ?
[02:36] <holstein> ronj: not sure
[02:36] <holstein> i think abogani got a little discouraged
[02:36] <ronj> hm
[02:36] <holstein> doing everything on his own
[02:36] <ronj> sure
[02:36] <holstein> i think he's back into it now though
[02:36] <holstein> there a PPA for them
[02:36] <holstein> for natty
[02:37] <ronj> yup I'm testing it right now
[02:37] <ronj> but we're redoing things we did this summer :-/
[02:37] <ronj> (I mean the discussion, testing is always good)
[02:37] <holstein> :)
[02:40] <ronj> holstein, what are your minLatWithNoXruns for generic/lowlat/realtime?
[02:40] <holstein> to be honest
[02:40] <holstein> with a generic or lowlat
[02:40] <holstein> and my firepod
[02:40] <ronj> generic/lowlat/realtime
[02:40] <holstein> i cant start it without xruns
[02:40] <holstein> BUT i have tested a bit with a USB device
[02:40] <ronj> well, excluding the first few seconds
[02:40] <holstein> an maudio transit
[02:41] <holstein> and internal cards
[02:41] <ronj> oh ok
[02:41] <holstein> and the performance is much more similar all the time
[02:41] <holstein> quite tolerable
[02:41] <holstein> i still use the -realtime though
[02:41] <ronj> but with your fw card, increasing the delay, were you able to get to no xruns on lowlat?
[02:41] <holstein> i can always push a little harder
[02:42] <holstein> ronj: not reliably
[02:42] <ronj> hmmm
[02:42] <holstein> i think i was tring around 11ms
[02:42] <holstein> or so
[02:42] <ronj> interesting
[02:42] <holstein> maybe i did 20ms
[02:42] <holstein> i'll have to try again
[02:42] <holstein> now that i have a laptop that is easy to test all kernels and all interfaces with
[02:43] <ronj> will see with the recent kernel but with my TI chip I had consistent generic:notreliable/lowlat:4ms/realtime:2ms
[02:43] <ronj> weird yours is not consistent
[02:43] <ronj> yup
[02:43] <holstein> ronj: thats great
[02:43] <holstein> what device?
[02:44] <ronj> Startech EC1U2F
[02:44] <holstein> and, is this 10.04?
[02:44] <holstein> 10.10?
[02:44] <holstein> jack2?
[02:44] <holstein> i have falks PPA with jack2 in 10.04
[02:44] <ronj> well these tests were this summer, on 10.04pre
[02:44] <ronj> jack2
[02:44] <ronj> falktx ppa yes
[02:44] <holstein> i think lowlatency is the future
[02:45] <holstein> the near future at least
[02:45] <ronj> the future are singing kittens
[02:45] <holstein> lol
[02:50] <ronj> holstein, you'll have stuff to report to Alessio once done with your benchmarks?
[02:51] <holstein> sure
[02:52] <holstein> i'll need to install natty though
[02:52] <holstein> i think thats where he is right?
[02:52] <ronj> yes
[02:52] <ronj> beware, the ubustu iso is picky these times
[02:52] <ronj> just install the minimum audio selection
[02:52] <holstein> yeah, GRUB install changed
[02:53] <holstein> on the live CD
[02:53] <ronj> yup, and dependency issues in the video packages
[03:25] <ronj> holstein, did the key to show GRUB change from SHIFT to something else?
[03:25] <ronj> -lowlat successfully installed but I can't boot it :P
[03:25] <ronj> when I press shift nothing happens
[03:26] <holstein> ronj: not that i know of
[03:26] <holstein> but i always go in and unhide it
[03:27] <ronj> uh I guess it's in grub.cfg?
[03:28] <holstein>   /etc/default/grub
[03:28] <holstein> i do
[03:28] <holstein> #GRUB_HIDDEN_TIMEOUT=0
[03:28] <ronj> ok
[03:28] <holstein> and sometimes
[03:28] <holstein> GRUB_TIMEOUT=-1
[03:28] <holstein> when i dont want the time
[03:29] <holstein> timer*
[03:29] <holstein> ronj: and run sudo update-grub afterward
[03:29] <holstein> to apply the changes
[03:29] <ronj> F*CK when installing lowlatency I also updated my packages, and now I'm unable to login
[03:29] <ronj> ultra-meh
[03:29] <ronj> meh
[03:29] <ronj> meh
[03:29] <ronj> meh
[03:30] <holstein> :/
[16:21] <balleyne> I recently upgrade to Ubuntu Studio 10.04 from 9.04 (through 9.10), and when I run qjackctl and try to connect to my presonus firepod soundcard, it fails and the messages window says "jackd: unknown driver 'freebob'" and when I try 'firewire', it says "cannot load driver module firewire". Help?
[16:23] <holstein> balleyne: i need to run
[16:23] <holstein> BUT
[16:23] <holstein> i have that hardware
[16:23] <holstein> try running sudo qjackctl
[16:23] <holstein> se if you have permissions issues
[16:24] <holstein> you want to use the 'firewire' driver
[16:24] <balleyne> holstein: ah, ok, thanks!
[16:24] <holstein> google 'ubuntu firewire wiki'
[16:24] <holstein> and you'll see some particulars on fixing permissions
[16:24] <balleyne> holstein:great, thank you
[16:24] <balleyne> holestin: I remember doing that for older versions of Ubuntu Studio, that could well be it... I'll check it out, thanks!
[16:24] <holstein> BBL... if you need... also #opensourcemusicians :)
[16:25] <balleyne> holstein: awesome, thanks :)
[16:27] <balleyne> holstein: fixed it already, thank you!
