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