studiobot<Eickmeyer> @teward001 I completely forgot about lp:new-session-manager and lp:dragonfly-reverb needing reuploads.15:50
studiobot<Eickmeyer> new-session-manager had a binary namespace issue and dragonfly-reverb had some unused copyright lines (upstream removed a lot of stuff).15:51
OvenWerksEickmeyer: sorry for the rant to the rant on the mail list... 16:52
EickmeyerOvenWerks: No, I 100000% agree with you, but not sure about the PC going away. The gaming market is too rich.16:52
EickmeyerMy method was deflection, your method was more pointing-out how myopic his assumptions are. Unfortunately, that's the author of our (now outdated) audio handbook which may end-up disappearing.16:54
OvenWerksEickmeyer: those guys: A) don't buy PCs, they make them and B) are willing to spend mac like prices or more.16:54
OvenWerksEickmeyer: I do not know of any local computer store where one can go in and buy a game ready PC.16:56
OvenWerksmaybe I am looking on the wrong shelf or something16:56
OvenWerksEickmeyer: can I get you to test something? If you have a copy of carla 2.2 around still.16:59
OvenWerksIf you could try the recipe in my last comment at: https://github.com/falkTX/Carla/issues/123717:00
OvenWerksSee if either Carla freezes or at least zita-a2j seg faults17:00
studiobot<teward001> @Eickmeyer [@teward001 I completely forgot about lp:new-session-manager and lp:dragonfly-rev …], ok i'll add it to the list17:00
EickmeyerOvenWerks: I'll give it a shot.17:01
OvenWerksI have found the fresh reboot is not needed... untill after :P17:02
EickmeyerOvenWerks: I don't know how to accomplish step 2. What's the command line for that?17:08
OvenWerksjack_control start17:09
OvenWerksstudio controls uses jack_control intyernally17:09
OvenWerksso it is ok to start jack using controls17:10
OvenWerksEickmeyer: ^^17:11
EickmeyerOvenWerks: I just tried it, and by step 9 could not reproduce. Carla is not frozen for me.17:13
EickmeyerHowever, zita-a2j did segfault.17:13
OvenWerksyou will find it does not with carla 2.1 I think17:13
EickmeyerI'm using Carla 2.2-RC1 in groovy.17:14
OvenWerksI think carla has a bloated jack callback17:14
EickmeyerWell, like I said, couldn't reproduce starting at step 9.17:14
EickmeyerCarla did not freeze for me.17:15
OvenWerksquite probably a callback for jack graph change or something17:15
OvenWerksI understand. That may be a difference in usb hardware or cpu or whatever17:16
EickmeyerThat's my guess. In this case, I'm using an old 2010 Mac Mini as the hardware. Didn't test with my main system which uses a USB audio interface (not a cheap one) as its main sound card 90% of the time.17:17
OvenWerksIt is interesting that zita-j2a for me does not freeze Carla but does also segfault17:17
EickmeyerThat tells me there might be an issue with the zita-ajbridge code.17:18
OvenWerkspossibly, but it doesn't matter if it is zita-ajbridge 0.8.2 or 0.8.4. I tried both17:19
OvenWerkscontrol c is the correct way of stopping zita-ajbridge BTW. anything else leaves a zombie process.17:20
OvenWerksit is also what the author says.17:20
EickmeyerHuh. Still, a segfault is pretty bad.17:22
OvenWerksI think what happens is that zita when it receives the ctrl c: removes it's jack ports and then tries to shut it's client and fails because carla, on getting a graph changed callback is still busy and so the client close segfaults.17:23
OvenWerksmany of the jack callbacks are RT (have to complete within one cycle) and are not supposed to include any call to the jack api.17:24
OvenWerksin my code I have had to save the callback info, set a flag and then have some other code take care of the info saved.17:25
OvenWerksCertainly in python but I also do so in c/c++ code17:25
EickmeyerGotcha. Ok, then it comes down to that I couldn't duplicate your issue using a USB headset I own.17:28
EickmeyerMy biggest issue, and what is probably bugging me most at the moment, is how the pulse bridge in Studio Controls in Fedora isn't working properly, if at all.17:29
OvenWerksEickmeyer: I have a spare partition (20G) I could install if there is an ISO.19:18
* OvenWerks has some Ardour work to do too...19:32
RikMillsEickmeyer: ok, I was just being dumb and tired as I so rarely do pristine-tar stuff. glad you got redkite done :)20:45
EickmeyerOvenWerks: Yeah, there's an ISO, let me see if I can get the link for you.20:55
EickmeyerRikMills: So, what I do is "pristine-tar list" which returns a list of what can be checked out. Then I do "pristine-tar checkout {latest tarball}". Then I "mv {tarball} .." to get it in the parent directory. After that, it's just a matter of "debuild -S (-d)" and an upload.20:56
EickmeyerOvenWerks: What I have won't represent F33 very well (because it's rawhide, and F33 branched earlier this week): https://kojipkgs.fedoraproject.org//work/tasks/3671/48863671/Fedora-Jam_KDE-Live-x86_64-Rawhide-20200807.n.0.iso21:00
RikMillsEickmeyer: yep, I was just not thinking properly21:19
EickmeyerRikMills: Happens to all of us. :)21:20
RikMillsindeed (insert Teal'c gif)21:23
OvenWerksEickmeyer: ok I will check this one first... then maybe upgrade or wait for an iso I can play with.21:33
OvenWerksEickmeyer: RE: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244 there is no such package that I can see... and it looks like user trouble rather than an actual fault21:47
ubottuLaunchpad bug 1872244 in jackd-defaults (Ubuntu) "Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen)" [Undecided,Confirmed]21:47
EickmeyerOvenWerks: To be fair, the Rawhide ISO is fairly close. About a week ago they pushed a change to the build system which broke Jam, and they're just now getting it fixed. I use Rawhide because it's developed alongside F33 at this point, and will be until F33 releases.21:54
EickmeyerOvenWerks: RE bug 18722144, I just invalidated it. You're absolutely right, that was a support request, not a bug.21:56
ubottuError: Launchpad bug 18722144 could not be found21:56
Eickmeyerer... bug 187224421:56

OvenWerksEickmeyer: the iso DL keeps dumping out... oh well half way through21:58
EickmeyerThat's very strange. It shouldn't, koji is the "source of truth" for the builds.21:59
OvenWerksright now it says paused22:00
OvenWerksmust have been a bad keystroke22:01
Eickmeyerbad keystroke?22:01
OvenWerksThat paused it.22:01
EickmeyerAh, downloading now?22:01
OvenWerks but it failed about 20 sec after resume... restarted and quite again.22:02
EickmeyerOk, maybe I can get it on my nextcloud.22:02
EickmeyerOof, upload is going to take over an hour. Keep trying.22:04
OvenWerksseems to be stuck at 1.3 Gb22:05
EickmeyerMight be because Koji isn't mirrored, so you're downloading directly from the datacenter in WA DC.22:06
EickmeyerThough, I'm experiencing some slowness too. Might just be congestion everywhere.22:07
OvenWerksmy restart from 0 made it past 1.3 this time.22:27
EickmeyerOh good.22:27
EickmeyerMy upload still has 39 minutes, so it would be nice if your download finished before my upload.22:27
OvenWerksnow failing at 1.8...22:31
Eickmeyer*sigh*22:38
OvenWerksmade it to 1.922:40
EickmeyerWell, that's progress.22:47
OvenWerksfirefox fails to open a file browser... I think it is hard coded to nautilus :P23:02
OvenWerksanyway, it finally finished23:02
EickmeyerIt shouldn't. It's hardcoded to xdg-open.23:03
OvenWerksmaybe kubuntu does not have that set up... or maybe I am remembering xfce but that was set with thunar as favoured file manager23:07
OvenWerkseverything else opens the right file browser23:08
EickmeyerIn Groovy xdg-open is set for Dolphin.23:08
EickmeyerStudio Groovy.23:10
