| Summary | 0000144: Playback disable | ||||
| Description | Playback disables "randomly", must exit and return. One scenario (not the only one): hit space bar to play from mixer window, possibly not in mode where this is possible, but then playback disabled totally, even when hitting play button with mouse. all it does is change the play button to pressed, clicking again unpresses, but no playback. | ||||

although its quite a lot of work, it would be really helpful if you could get some gdb backtraces when this happens. you don't have to run it under gdb - once it gets into this situation, go into the directory where your ardour executable lives, and type gdb ./ardour PID replacing PID by the pid of ardour (from the output of ps). once gdb gets to its command line, type "thread apply all bt" and send ardour-dev the output or paste it into a bugnote. this type of bug is caused by a deadlock on a mutex, but i can't track it down unless i can see where the deadlock is happening. thanks. feel free to ask if you have any questions. |

I'd be happy to do that - the only big question I have is on this part: "replacing PID by the pid of ardour (from the output of ps)" - what is this and how exactly do I get it?" once I know that I can do this - so if I'm understanding, I wait til this happens, then immedietely open up another terminal go to the executable and gdb all I need is to understand where to find PID :) |

you can find the pid (or process id) thus: ~> ps aux |grep ardour nettings 14535 0.0 16.7 86956 85928 pts/8 SL 13:50 0:00 ardour nettings 14638 0.0 0.1 1828 624 pts/10 S 14:12 0:00 grep ardour ^^^^^-->this is the process id |

Reminder sent to nquit Did you ever get around to doing this? It would be very helpful. |

I also have the this problem. I can't do any playback. I accidentally touched the scrubs button, and marked a section. After that, playback is disabled for this session. I have tried to exit ardour and load the session, with the same result. I downloaded ardour .9beta8 and compiled it. Started it with the line gdb /usr/local/ardour/bin/ardour, and commanded run. Loaded the session when the window came up. Stopped the program (pressed Ctrl-C in konsole) and did a "thread apply all bt" on the gdb command line. Output follows. Hope this helps:-) Thread 7 (Thread 81926 (LWP 445)): #0 0x406cb61a in poll () from /lib/libc.so.6 0000001 0x084be8a5 in ARDOUR::Session::midi_thread_work() () at basic_signal.cc:25 #2 0x084be833 in ARDOUR::Session::_midi_thread_work(void*) () at basic_signal.cc:25 #3 0x40296e31 in pthread_start_thread () from /lib/libpthread.so.0 0000004 0x40296eaf in pthread_start_thread_event () from /lib/libpthread.so.0 0000005 0x406d430a in clone () from /lib/libc.so.6 Thread 6 (Thread 65541 (LWP 444)): #0 0x402995d4 in __pthread_sigsuspend () from /lib/libpthread.so.0 0000001 0x40299398 in __pthread_wait_for_restart_signal () from /lib/libpthread.so.0 #2 0x00000020 in ??

I never tried using the scrub button I have been madly trying to recreate my version of this and it has yet to do it again |
|
|
As reported boerre, i pressed scrub, and could not playback, transport remained stuck, so i checked the options window and notice that the transport option was set to scrub, and the only way i could change the option was editing the xml configuration file and removing it from there (can't remember if it was at the ardour.rc file or at the session file). What is strange is that there is no pulldown option "Scrub" at the transport, normally. Regards. |

|
Unless someone can duplicate this in 0.9beta11, i will close this bug in a week. |
|
|
for some reason, i missed the fact that this was occuring in scrub mode. scrub mode is going to be removed for the 1.0 release. it is too broken, and is arguably pretty useless. |

believed resolved. |
