* apw gets his machine back together ...07:37
smbapw, What did you do to it?07:37
ppisatimoin07:42
apwsmb, heh, put it back together after a parental visit ...07:46
apwppisati, moin07:46
apwNahesh, done07:47
smbapw, Ah, so sort of putting the office back together. :)07:47
apwsmb, that indeed07:47
apwsmb, but nowadays I have so much stuff plugged into my machine I think the only empty port is the firewire one07:47
smbCan see that happen. Maybe time for a docking bay. :)07:48
apwsmb, i wonder if this heap has one ... its pretty old so perhaps they are nice and cheap now07:52
smbapw, That is one of the things, that ThinkPads seemed to be good at. At least those seemed to have an additional docking connection. Most other seem to only offer a usb attachment.07:55
apwsmb, yeah don't see no stinking connector on it ... sigh07:55
* apw waits for his machine to update to the frozen archive08:07
apwonly 89 updates08:07
ppisati237 here...08:08
apwppisati, you are just not trying hard enough08:08
ppisaticuriosly just 76 on my panda... uhmm...08:11

diwicis there a name for Q yet? 08:12
apwdiwic, not that i have seen yet no?08:12
diwicok08:12
apwi assume we really need to know before long though08:12
diwicyeah I feel so too08:12
apwdiwic, its normally on markshuttleworth.com when its there08:12
smbdiwic, While you are here and I remember...08:14
apwright before i get all settled in for the day i am going to reboot into todays 'fun'08:14
smbdiwic, I know its probably not the main target thing... but do you know who would be interested / responsible for encoding into mp3 (from rhythmbox or other applications)08:15
diwicsmb, who as in person or application?08:15
diwicsmb, not understanding the question really08:16
smbdiwic, In person (I sort of know its done trhough gstreamer stack)08:16
smbThe problem I see is a) its not working correctly b) all visible ways of modifying the used gstreamer chain have gone08:17
smbhttps://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/94598708:17
ubot2Launchpad bug 945987 in rhythmbox "No Settings are available in "Preferred format", only preset defaults are used" [Undecided,Confirmed]08:17
smbThat bug report is about b) but also (without knowing so) complains about a)08:18
* diwic reads bug08:18
smbdiwic, The settings dialog is purely a UI thing I guess... Not sure why it was seen as not needed anymore... The other problem seems to be that something seems wrong with the chain and I am not sure where the heck it would be found nowadays...08:20
diwicsmb, hmm, can it export to ogg just fine, only mp3 is the problem?08:21
smbdiwic, Right, ogg seems ok08:21
smbdiwic, In essence the produced mp3 is vbr but has no xing header08:21
smbSo bitrate and length displayed are way off08:22
* ppisati -> reboot08:22
diwicsmb, ah, so it *can* export to mp3, but the result is broken?08:22
smbdiwic, right08:22
smbAnd without the dialog there is no way to verify or modify the way it does the encoding 08:23
smb(eg. have a different quality setting)08:23
diwicsmb, I know a few gstreamer people, but not sure if any of them are into mp308:24
diwicsmb, gstreamer-devel could be a place to ask08:25
smbdiwic, I think a good first step would be to get the dialog working08:25
smbapw, You cannot hear us anymore08:25
diwicapw, if your having mumble trouble, can you please pastebin me the output of "pacmd ls" 08:26
smbdiwic, Ok, I will try it there then08:26
apwdiwic, i am having 'not using the damn connector that is marked selected in the g08:26
apwgnome thingy' trouble at the moment08:26
diwicapw, IIRC the mumble audio wizard allows you to select a device there as well08:27
diwicapw, maybe it overrides gnome/pulseaudio's default setting?08:27
apwdiwic, well it didn't before the last reboot, wtf, i hate hate hate pulse08:28
apwopen letter to pulse "do what i say or get deinstalled"08:28
diwicapw, you can file a bug for it, against pulseaudio. Then I can spam you with requests to try newer versions and open bugs in upstream bug trackers. ;-) 08:29
* apw cries08:29
diwicapw, seriously though, I *do* want to fix it. 08:29
apwdiwic, yep i know, and i want it to work08:30
apwdiwic, its just every bloody morning ... every bloody time ... its broken somehow, i hate it08:30
apwdiwic, what against bugness fun08:30
apwdiwic, and compared to the utter hideous complexity of pulse the kernel seems easy08:30
smbapw, At least its not you disk or raid that is not working...08:31
apwsmb, heh ... at least that08:31
apwdiwic, pus08:31
* apw fails to use his keybaord as well ... sigh08:31
diwicapw, pulseaudio is far from perfect; but we're left with two options 1) be patient and try to resolve the bugs that still are there or 2) replace it with something else.08:36
ppisatiok, seems i've some mumble/pulse audio prob too08:36
ppisatii can hear you08:36
apwdiwic, heh understood indeed... its just an ongoing torture ;)08:36
ppisatibut you can only hear my music! :)08:36
smbppisati, We only hear your music08:36
diwicppisati, the output of "pacmd ls" please?08:37
ppisatidiwic: a mumble restart fixed it :)08:39
apwhttps://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/98288608:39
ubot2Launchpad bug 982886 in pulseaudio "selected input in the gnome input selector is not the input that mumble uses" [Undecided,New]08:39
apwdiwic, ^^08:39
ppisatidiwic: pulse didn't pick the correct input (mic vs $somethingelse)08:39
diwicapw, thanks08:40
apwdiwic, i have the 'default' selected in mumble, and its stubbonly the 'inbuilt audio' and not the usb mic08:40
diwicapw, hmm, maybe it has something with the "media-role:phone" that mumble identifies itself with08:42
diwicapw, I guess that if you run "pacmd stat" it would show the snowball mic as default source?08:44
apwDefault source name: alsa_input.usb-BLUE_MICROPHONE_Blue_Snowball_201111-00-Snowball.analog-stereo08:45
apwdiwic, ^^08:45
diwicapw, yep. So the analog input is either because of an media-role override or application override.08:45
diwicapw, how reproducible is this?08:46
apwdiwic, its the first i've seen this i think, where its not possible to change it08:47
apwdiwic, i updated today and rebooted, from fridays archive to todays08:48
apwdiwic, i have tried moving mumble to the blue and that works and when i put it back to 'default' it goes back to the wrong one08:48
diwicapw, ah, interesting. Can you execute this command "pacmd set-log-level 4". Then switch back to 'default'. Then pastebin me "grep pulseaudio /var/log/syslog"08:49
apwgrep pulseaudio /var/log/syslog08:55
apwdiwic, http://paste.ubuntu.com/932257/08:55
diwicapw, thanks. PulseAudio says "not guilty": "Apr 16 09:55:02 dm pulseaudio[2964]: [pulseaudio] module-stream-restore.c: Not restoring device for stream source-output-by-media-role:phone, because already set"08:58
diwicapw, let me dive into the mumble source code to see how it opens the pulseaudio device. It'll take a little while so use whatever workaround you prefer if you need audio.08:59
apwdiwic, ok thanks09:03
apwdiwic, oh and just for completeness i have restarted mumble following those being attached and made the defaults; to be in this position.  plus audio output changes approriatly just fine ... i also have usb speaker fun09:05
jorgesuarez_hi, is there some place where is explained the removal of -server flavour for 12.04? there are no technical implications? i find the release notes too brief09:06
apwjorgesuarez_, there were no configuration differences which could not be done in userspace09:06
apwjorgesuarez_, therefore there was no point in building two identicle binaries09:06
jorgesuarez_so, preemption and timer interrupt can also be switched? didn't know09:07
apwjorgesuarez_, no but they had the same settings09:07
jorgesuarez_i thought based on https://help.ubuntu.com/10.10/serverguide/C/preparing-to-install.html#intro-kernel-diffs that preemption and timer interrupt were different on -server09:08
jorgesuarez_maybe something has changed since 10.10?09:08
apwthat was back in 10.10 thats practically the jurassic :)09:08
jorgesuarez_but i can't find non-jurassic docs ;)09:09
apwdecisions to change things like that are discussed at UDS and would be in theory at least documented in the write up of those09:09
apwon the blueprints for each release since09:09
jorgesuarez_the blueprints on launchpad, you mean?09:10
apwthe one and only09:10
jorgesuarez_i'll take a look then, thanks!09:10
jorgesuarez_(sorry, i'll be afk now but come back later)09:11
diwicapw, it's mumble's fault. It explicitly sets the wrong device to be used. See comment #2 in your bug for some explanation.09:34
apwdiwic, bad piece of junk ... did you shove it over to mumble ?09:34
apwdiwic, i vote for (1) so it moves correctly09:35

tgardnerherton, which Lucid patch has failed to be verified ?12:44
henrixtgardner: the reverted patch was 73ae7483541a7e5e90cc4ce09a08763d86945486.12:44

desrtno.  it's on the to-merge-in-next-version repo13:43
desrtintel-drm-next iirc13:43
tgardnerdesrt, it seems like it might qualify as  a bug fix for the 3.4 merge window, though I haven't actually looked at the code. Have you asked upstream about it ?13:45
desrtupstream has taken it13:45
desrtthe freedesktop.org bug is marked FIXED13:46
tgardnerdesrt, no, I meant have you asked them to get it into the 3.4 merge window ?13:46
desrtoh.  i have no idea.13:46
* desrt has no idea how the kernel works13:46
tgardnerdesrt, you don't necessarily have to know how it works. just ask them to merge that specific patch because it fixes your problem. you never know, they might listen.13:47
desrti'd guess that drm-intel-next is what will go into the next release?13:48
tgardneryep, 3.513:48
desrttgardner: so i think it's already slated to be merged (along with a bunch of other things)13:48
desrtah13:48
tgardnerwhich is months away yet13:48
desrtso you mean a 3.4.x stable release13:48
tgardnerdesrt, 3.4 isn't in the can, so it could still make it as a bug fix13:48
desrti guess i can ping on the freedesktop bug...13:49
tgardnerdesrt, right13:49
desrtokay.  done13:49
desrthow does that affect ubuntu?  aren't we on 3.2?13:49
tgardnerdesrt, our policy is that we typically only pull fixes from upstream, either 3.2 stable or Linus' repo.13:50
desrtgotcha13:50
desrtso if they're willing to land it on a stable branch then you'll take it13:51
tgardnerdesrt, correct, but it _first_ has to get merged in Lunus' repo13:51
