[11:12] <ailo> abogani: -lowlatency is not performing as good as before. Do you know why?
[11:13] <ailo> Performance while watching flash videos seems to have improved, but I can't get as low latency as before.
[11:13] <persia> ailo: As you appear to have found issues with the change to 2.6.38 for both -generic and -lowlatency, I wonder if it's something related to the version change, rather than something about specific binaries.
[11:14] <ailo> persia: I should do some more testing. I should compare some different kernels to see if it is only kernel related too.
[11:15] <ailo> persia: Do you think it's possible to tune priority outside of the kernel?
[11:16] <persia> Yes, it could be something else, but the key is that you need to consider the kernel version as much as the config.
[11:16] <persia> I don't understand the question about priority
[11:17] <ailo> If I wasn't dreaming, I saw a huge difference with the same -generic kernel (2.6.38-1) after a few days when I tested again
[11:17] <persia> That points at something else then.
[11:17] <ailo> persia: Maybe nouveau has higher priority then before?
[11:18] <persia> Huh?
[11:18] <ailo> just guessing. I'm thinking maybe it's unity-related somehow.
[11:19] <ailo> I don't know anything about what could adjust the balance in setting priorities
[11:19] <persia> What do you mean "setting priorities"?  Also, what does this have to do with nouveau or unity?
[11:20] <ailo> persia: I'm just thinking some work has been done on Unity, which causes audio devices to get less priority. 
[11:20] <ailo> As I said, I have no idea what would do that, or how.
[11:20] <persia> What do you mean by "priority"?
[11:21] <ailo> What should I call it, when jack is less reliable than before? I guess it could be anything distracting it.
[11:24] <persia> I don't understand at all.
[11:24] <persia> Please describe the issue you are seeing, specifically, and without guessing as to source.
[11:24] <ailo> persia: I get occasional xruns using 64 frames/period. Just a couple of weeks ago, I got zero.
[11:25] <ailo> Now, I can probably use 128 frames/period with getting 0 xruns
[11:27] <ailo> The most recent change has been with graphics. Flash has improved, but it doesn't seem to have affected audio performance
[11:27] <persia> Ah, OK.
[11:28] <persia> You'd want to check recent upgrades, but I'd suspect JACK, the kernel, or the core libraries before anything else.
[11:28] <persia> edge applications are unlikely to affect anything.
[11:29] <persia> Except in the case where some application has periodic or similar resource use that interrupts current operations.  You might check the usage of the various indicators and applets: I know network-manager was unpredictable: it may be that more things are becoming so (in which case, these may be better removed)
[11:31] <ailo> persia: The -generic was performing as well as -lowlatency for a while (2.6.38-1), but stopped doing that. Now, it's not working that great at all.
[11:54] <ailo> Seems like qjackctl is freezing up Youtube, even when jackd is not running.
[11:57] <persia> That's highly unlikely, unless you have hardware memory issues.
[11:58] <ailo> It's only flash freezing. Nothing else
[11:59] <ailo> I mean, changing to another flash video makes the browser freeze, sorry
[11:59] <ailo> Trying to see what log to look into
[12:01] <ailo> As soon as I quit qjackctl the browser starts working again, so I'm assuming this has something to do with PA
[12:03] <persia> Ah, yes.  It may.  I forgot about the qjackctl/PA thing.
[12:06] <ailo> persia: right, of course. qjackctl suspends PA entirely, while jackd only grabs the device that is to be used, if not available
[12:06] <persia> Right.  That needs cleaning up.
[12:46] <abogani> weird
[12:46] <ailo_at> I added a new set of test results in https://wiki.ubuntu.com/RealTime
[12:48] <ailo_at> 2.6.38-1 lowlatency seems to perform as well as before, while the same version of  -generic has changed
[12:59] <scott-work> TheMuso: did you push the patch for the gnome-classic xsession bug?  i got a bug email and just wanted to make sure what was going on :)
[13:00] <abogani> ailo_at: Amd64 or i386? Do you have -1-lowlatency and -3-lowlatency installed side by side on the same machine?
[13:02] <ailo_at> abogani: I must admit I have yet not tested on amd64. I will install it today.
[13:03] <abogani> ailo_at: It isn't necessary.
[13:03] <ailo_at> These tests were all done on the same machine
[13:04] <abogani> No packages update in between, right?
[13:04] <ailo_at> Not between the tests made on the same day
[14:21] <scott-work> abogani:  how do i get *your* kernel from git?
[14:21] <scott-work> abogani: i'm not really familiar with git but i understand it's a cvs much like other and i can find the commands easy enough
[14:21] <scott-work> abogani: but from which repo do i need to get your kernel and how do i make sure it is yours
[14:22] <ailo_at> I did "git clone git://kernel.ubuntu.com/abogani/ubuntu-natty-lowlatency.git aboganis-lowlatency"
[14:25] <ailo_at> scott-work: If you just want to get the source, that command should do.
[14:47] <scott-work> ailo_at: thanks!
[14:48] <scott-work> i wasn't sure which repository or how to get his directly but this should do it
[14:48] <scott-work> abogani: this is the kernel you wanted me to get isn't it?
[14:49] <abogani> scott-work: Yeah.
[14:51] <scott-work> abogani: i will download it tonight then :)
[14:52] <scott-work> abogani: do you want to mention something now for me to look at in particular tonight?  or wait until tomorrow morning?
[14:53] <abogani> scott-work: Clone also meta git tree.
[14:53] <scott-work> by the way, "tonight" for me is about +10 hours hence and "tomorrow morning" is about +24 hours
[14:53] <abogani> scott-work: Ok
[20:11] <ailo_at> scott-work: Is the video task-sel still supposed to fail?
[20:49] <scott-work> ailo_at: no, no...it was fixed when we dropped qdvdauthor from the seeds
[20:49] <ailo_at> scott-work: My install failed today
[20:49] <scott-work> ailo_at: i say "fixed", but maybe there is another problem happening (or continuing to happen)
[20:52] <ailo_at> Also, I have corrupted graphics, so I'm unable to use the system at all :(
[21:09] <scott-work> ailo_at: are you installing this onto a vanilla ubuntu install and then "upgrading" to ubuntu studio?
[21:10] <scott-work> or a full install from dvd?
[21:10] <ailo_at> scott-work: Full install from DVD, except for the video task-sel
[22:11] <TheMuso> ScottL: Yes that was me.
[22:11] <TheMuso> I've also updated to the latest Debian revisions of jack and jack2, as well as requested a sync for latest libffado from Debian.
[22:36] <ScottL> TheMuso, i didn't think it would be anyone else but i wanted to make sure nothing funny was going on
[22:36] <TheMuso> heh ok.
[22:36] <ScottL> TheMuso, plus i wanted to say, "thank you" :)
[22:36] <TheMuso> np
[22:46] <ScottL> so ailo_at , i might try to install the metapackage on my laptop just to see what happens
[22:47] <ailo_at> ScottL: I should retry my installation. It was amd64. Video didn't install as I said and for some reason graphics were corrupted. Grub menu had tiny, tiny fonts.
[22:48] <ScottL> ailo_at, i don't know really
[22:48] <ScottL> ailo_at, i remember that when i was testing the latest alpha image i had a failed installation on that computer
[22:49] <ScottL> which as also suffering trouble with kernel panic
[22:49] <ScottL> i thought it was my computer to be honest at the time and didn't pursue it
[22:49] <ailo_at> Me too (thinking it was my computer)
[22:49] <ScottL> lol
[22:51] <ScottL> i hope my computer doesn't explode when i try to install the video-meta :P
[22:51] <ailo_at> I would blame my corrupted graphics on the video driver. Maybe it was guessing my monitor settings wrong?
[22:53] <ailo_at> ScottL: So only two daily builds are saved?
[22:55] <ScottL> that is all that i am aware of
[22:55] <ailo_at> ScottL: Perhaps better to install from the alpha image, then. That should work, I guess.
[22:55] <ailo_at> I'm giving it another go today
[22:56] <ScottL> ailo_at, not necessarily, (alpha image should work)
[22:56] <ScottL> when installing the video-meta i had some weirdness going on with mime-types
[22:57] <ScottL> i took a screen shot of the output but not sure who should see it :/
[22:58] <ScottL> going outside with kids/dogs
