--- Comment #1 from Felix Miata mrmazda@earthlink.net --- Definitely has been happening on my main KDE3 desktop going far too far back to remember.

--- Comment #4 from David Rankin drankinatty@suddenlinkmail.com --- Created attachment 778930 --> http://bugzilla.opensuse.org/attachment.cgi?id=778930&action=edit kcrash for this bug, captured while writing this bug.

I can confirm this still occurs daily on 42.3. It seems to occur more frequently when the number of windows and desktops in use increase. I generally have apps running on 3-desktops and is triggered, as far as I can tell, on a window focus change after some random number of changes has occurred. (In fact I just triggered it minimizing konsole and saved the backtrace). The kde sound them plays fine on on desktop switches, minimize, restore, etc.. until the crash occurs, then the system sounds are gone (until you restart kde)

There are continual logs to xsession-erros, e.g.

jack server is not running or cannot be started akode: Guessed format: xiph KNotify::playTimeout KNotify::playTimeout X Error: BadWindow (invalid Window parameter) 3 Major opcode: 19 Minor opcode: 0 Resource id: 0x4400022 jack_client_new: deprecated Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started akode: Guessed format: xiph KNotify::playTimeout jack_client_new: deprecated Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started akode: Guessed format: xiph KNotify::playTimeout KNotify::playTimeout X Error: BadWindow (invalid Window parameter) 3 Major opcode: 19 Minor opcode: 0 Resource id: 0x3aed637 jack_client_new: deprecated Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started akode: Guessed format: xiph KNotify::playTimeout KNotify::playTimeout jack_client_new: deprecated Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started akode: Guessed format: xiph KNotify::playTimeout KNotify::playTimeout

was assigned to me, but this problem happened in libjack, not KDE3. So changed assignee.

Can you please alter the KDE:KDE3 repositories to point to ie: <path project="openSUSE:Leap:15.1:Update" repository="standard"/>

libjack0-1.9.12-lp151.3.3.1.x86_64 now is installed on my primary PC. It takes time for the no longer expected crash to occur....

I used to use xine as the audio backend in my kde3 days. Try executing this: jack_control start ; jack_metro -f 25 -b 30

and see if you can make a crash, you have to use ctrl c to exit jack_metro. Also we can test with zynaddsubfx and qjackctl. Execute zynaddsubfx from the command line than you need to start qjackctl from another console and then click the connect button. You should see zynaddsubfx in the left hand window, expand it and you will have out_1 and out_2 expand system in the right hand window you will have paybacks 1 and 2. Select out_1 and drag to playback_1 to connect, repeat with out_2. Now you should have sound from the keyboard of zynaddsubfx, play around and if you can't reproduce the crash you should consider switching to xine, I'm bugowner for xine.

Please post any useful information.

knotify has crashed apparently trying to start jackd I've looked for a phonon jack to run jack as a backend in kf5 but it doesn't appear to exist. In the days when I used kde3 I tried the jack audio backend with no success. Is jack the only available backend for kde3?

--- Comment #21 from Felix Miata mrmazda@earthlink.net --- (In reply to Yasuhiko Kamata from comment #20)

KDE3 also supports OSS (Open Sound System) (run "modprobe snd-pcm-oss" in order to work).

When, every boot? Once only? If not, can it be made automatic? Does anything else need to be done to prevent the crashing that still occurs as of KDE3 updates as of a month or so ago? KDE3 for 15.1 seems to be getting rebuilt every week or so.

Has no effect. Still crashes in the same manner, e.g.

$ cat /etc/modules-load.d/snd-pcm-oss.conf snd-pcm-oss

(having rebooted and restarted)

Using OSS is not a solution, but a workaround. This means that you can use OSS instead of Jack in KDE3 (KDE3 control center -> Sound & Multimedia -> Sound System -> "Hardware" tab -> Audio Device).

--- Comment #27 from Ilya Chernykh anixx@opensuse.org --- If it does not happen in Trinity, the problem could be in some of the old KDE3 patches.

http://bugzilla.opensuse.org/show_bug.cgi?id=1047852 http://bugzilla.opensuse.org/show_bug.cgi?id=1047852#c29

--- Comment #29 from David Rankin drankinatty@suddenlinkmail.com --- Is there a single repository where we have the complete KDE3 source tree (with all current patches) we can 'grep -r jack' and look at where it is being pulled in? Recreating the tree from .srpms will be time consuming, but doable. It may be helpful to compare the results of the same output against the TDE git tree. I have old copies of the the TDE tree for 3.5.13-sru that will probably suffice.

The knotify crash still occurs but sometimes it can occur in a few hours, sometimes it takes a day or so. It is triggered most often when several sound events are triggered in quick succession (such as scrolling the mouse-wheel over the desktop background to change desktop in quick succession)

If we think this is narrowed down to the kde3-kdelibs source, I'll start with that. At least that is were kdelibs/arts/knotify resides.

Still happening in 15.2. :(

I'm keeping this bug open until I get the time to build an old version of libxine which still has the arts backend, fortunately it's archived back to the end of 2004. Unfortunately jack is not compatible with arts anymore. You could maybe find someone upstream that maintains kdelibs3-arts who can integrate it with the latest jack

--- Comment #35 from Dave Plater davejplater@gmail.com --- The only thing that will fix this is either an older version of xine-lib that still builds the arts backend or possibly a much older version of jack that still works properly with kde3. I have a little bit of spare time so I'm going to see if I can extract the last version of xine-lib that can still be used for kde3 audio. I've never used kde3 with a jack backend but I used the xine backend for the entire time that I had kde3. This is like trying to find the right spark plugs for a vintage car or the right valve for an old radio
