Verbose pulseaudio log attached to the bug [12:02] nessita, yeah, I saw. So, it looks like the kernel is at fault here... [12:02] diwic, apparently... [12:03] diwic, I still have the installation on a separated partition, so if you need me to run more tests, just let me know [12:06] nessita, I guess rtg could set up a git bisect between 3.2 and 3.8 for you [12:06] diwic, sounds good [12:07] diwic, do we have a newer kernel in saucy? I could try that too [12:07] nessita, saucy is 3.10. [12:07] diwic, would you recommend that path? [12:08] nessita, I think you tried saucy at one point and it was still broken, right? [12:08] diwic, no, at that point you considered it wasn't going to help [12:08] or it likely wasn't ging to help [12:09] nessita, I still think it's more likely it does not help, but feel free to try [12:10] diwic, I have no leftover space in my disk for a separated partition, so I would have to upgrade this raring to saucy. Would you know if the transition is "smooth"? [12:10] nessita, try saucy from a live USB stick. [12:10] or is there a package with saucy's kernel for raring? [12:10] ah, can do that [12:10] nessita, btw, is your computer home-built? [12:11] nessita, or does it have a common name (like "Dell inspiron D505")? [12:11] diwic, I bought the separated parts and I assembled it [12:11] so, I guess the answer is "yes" [12:11] nessita, okay, what graphics card is in there? [12:12] nvidia gforce (grabbing exact model) [12:12] 8400 GS [12:13] diwic, FYI, I did not install the propietary drivers in the precise installation [12:13] nessita, since it has been the graphics showing up on the wakeup_rt tracer reports - do you have another card around that you don't use, you could try switching and see what happens? [12:13] diwic, hum, no, I don't have, and this MB does not have integrated graphics [12:13] nessita, okay [12:19] nessita, so, a long boring git bisect, or possibly switching graphics cards are my best bets at the moment - but saucy could be worth a try too if it is easy for you to test [12:20] nessita, but I'm far from sure it's the graphics card at all so don't go buy a new one just for this :-) [12:21] diwic, right, I wasn't planning on getting a new video card... is hard for me to understand how video can mess up with audio like this. Specially since this computer has "a lot" of cores, so I would expect audio and video to not mess each other [12:22] diwic, will do the sacuy test. I'm also happy to do the git bisect, but I'd need instructions/packages for that [12:22] nessita, yeah, I too think that is surprising. I'm not an expert on scheduling. And I'm not ruling out audio either, it's just that that biggest weirdness are these latencies. [12:23] oh my god, i can't even believe bfq and deadline came up in discussion as a reasonable thing to do [12:24] bug #1201528 [12:24] Launchpad bug 1201528 in alsa-driver (Ubuntu) "[Realtek ALC889] - Audio Playback Unavailable" [Undecided,New] https://launchpad.net/bugs/1201528 [12:27] heh oh man, raymond is on launchpad now ;O === fmasi_lunch is now known as fmasi [13:07] diwic: doesn't have to be a scheduling problem, but that is indeed weird stuff [13:08] i'd be interested to see if some of the power state latencies and stuff were correctly reported and if it's entering them [13:14] apw, I updated overlayfs. looks like it builds OK. maybe you could do your testing on it ? [13:15] rtg, is that post what i build this morning ... assume so [13:15] apw, just now. updated to v19 [13:15] rtg, ok [13:42] nessita, could you attach the output of /proc/interrupts ? It does not have to be any specific kernel or release. [13:45] diwic, sure, will grab them from this session. Do I need to "break" audio first? [13:46] nessita, does not matter. [13:47] ack, attached https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1201528/comments/41 [13:47] Ubuntu bug 1201528 in alsa-driver (Ubuntu) "[Realtek ALC889] - Audio Playback Unavailable" [Undecided,New] [13:48] diwic, properly formatted https://pastebin.canonical.com/95432/ [13:48] 45 is a busy one [13:49] FYI, audio playback is still working (haven't opened mumble yet) [13:50] nessita, just curious if nvidia and snd-hda-intel were on the same cpu but it seems like nvidia is spread across all CPUs. [13:51] and nvidia interrupts values seem "reasonable" [13:51] snd_hda_intel interrupts are crazy high [13:52] nessita, and this was raring, right? [13:52] diwic, yes, 13.04 with 3.8.0-26-generic [13:52] ok [13:53] that makes me remember... /me needs to download saucy iso [14:01] nessita, are you running with tsched=0 ? [14:01] diwic, not that I know of, let me check [14:01] nessita, if you are that could explain the large values on snd-hda-intel [14:02] diwic, can you please remind me where to look? [14:02] nessita, /etc/pulse/default.pa [14:03] diwic, full content of the file https://pastebin.canonical.com/95438/ [14:03] i don't see tsched there [14:04] nessita, nope, looks like the origina [14:04] l [14:04] yeah, my recall was that I reverted all the changes I tried [14:10] apw, laid down some hacks on lttng in unstable. can you have a look to make sure what I did makes sense ? [16:12] hello [16:13] hi [17:24] ohsix, I see that diwic left, but just wanted to mention that booted a saucy live from pendrive, and auido playback broke as soon as I opened mumble, attached to the bug the pulse verbose log (with lots of underuns), and the /proc/interrupts from before === fmasi is now known as fmasi_afk
