banjo Posted December 7, 2004 Report Share Posted December 7, 2004 Well, I almost got there with my recording project. I am trying to record from line-in into Audacity so that I can capture some recordings that I have made. I can record OK if I just run Audacity and then start recording, but the preferences default to monaural. When I set the preferences to stereo, and then click on OK, Audacity crashes with a Segmentation Fault. In fact, any time I display the Preferences dialog and then click on OK, without even touching anything in the dialog, Audacity crashes with a Segmentation Fault. I uninstalled Audacity and then reinstalled it with no effect. Anybody have a clue why this might be happening? Or, if not, is there a recording application out there that actually works? This is really getting frustrating. Thanks in advance Banjo (_)=='=~ Quote Link to comment Share on other sites More sharing options...
banjo Posted December 7, 2004 Author Report Share Posted December 7, 2004 (edited) Well, here I am answering my own question again. D'oh Since Audacity was crashing while setting its preferences, I found the .Audacity file and opened it in vi and made the changes manually. Then, when I ran Audacity again it came up with the settings I wanted. I managaged to record from line-in using stereo and life is good. The program works fine for that. I would still like to get properties working, but for now it is set up the way I need it. Maybe tomorrow I will go in and blow away the .Audacity file to see if it can fix itself and create a new one. But for tonight, my brain is fried. Linux rocks!

banjo Posted December 8, 2004 Author Report Share Posted December 8, 2004 I continue to slog along trying to make Audacity behave. I went back in tonight and blew away the .Audacity config file and then ran the program again. Audacity came up, and reinitialized itself and I could display the preferences dialog, set my preferences, and close it fine. I displayed the dialog box several times and it was working as expected. Then, I shut down the program and started it up again. Now, every time I display the preferences dialog and click on OK the program crashes. If I click on Cancel it keeps running, so something is going wrong trying to write to that file. I am very confused. I forge onward.

banjo Posted December 8, 2004 Author Report Share Posted December 8, 2004 In an effort to understand what is going on with my Audacity, I downloaded the source code for 1.1.1-3 and took a look at it. It appears that the preferences are being written out by the write() method of a wxConfig class. So it is probably crashing in there somewhere... (null pointer?) Here is where it gets interesting. The program is using classes from wxWindows, which is a set of platform independent C++ classes used to build GUI apps........ which is built on top of GTK+, which is a set of platform independent classes used to build GUI apps........ which...... So, the application itself seems to be several portability layers removed from where the actual work is done, and finding where the problem actually occurs could be a bit dicey. Anyway, as a backup app. I downloaded GramoFile, which is based on curses (remember that? .... yee haw) and I compiled it and ran it and it runs. It's ugly, but it runs. I was able to record from my microphone directly into a .wav file. Where there is a will, there is a way. Is nobody else using Audacity? Pity. Seems like a nice app. if I can get it to stop crashing. I seem to be talking to myself on this topic so if anybody wants me to just shut up, let me know and I will take it offline. I'm just sitting here playing with my mental blocks. Linux rocks!

I'm just sitting here playing with my mental blocks. Don't be discouraged - at least you're providing a clear path for those who may follow you... On an unrelated point - why do you have such wide margins? :huh: Quote Link to comment Share on other sites More sharing options...
banjo Posted December 8, 2004 Author Report Share Posted December 8, 2004 (edited) You mean, why the vertical format? I just got tired of having the wimpy forms on mailers like Yahoo etc. breaking my lines in ugly places....yuk. So, I go ahead and type a nice looking line and the mailer form breaks it at stupid places and makes it look like this paragraph. And then sometimes I go ahead and enter the text with no returns and the stupid mailers will not break the line at all and I have to read the line using the scrollbar at the bottom. So, I just got into the habit it typing teensy weensy little short lines that fit inside of the form. Maybe this form is a bit more friendly. call me crazy. Back on topic.... part of the reason that I am pursuing this is to figure out how all of this hangs together so that I understand why I fall so often into Dependency Hell and how to get out of it once there. I tried to build Audacity 1.2.2 last night and I didn't even get through ./config before it choked. Seems I need a wx_config or something that it could not find. Probably a development kit piece that I don't have. That is what precipitated my descent into source code and the wxWindows and GTK+ recursion.

adamw Posted December 9, 2004 Report Share Posted December 9, 2004 banjo: you probably don't have the wx -devel libraries installed...run rpmdrake, search for 'wx', and install anything with -devel in the name. Quote Link to comment Share on other sites More sharing options...
banjo Posted December 9, 2004 Author Report Share Posted December 9, 2004 adamw, Thanks for the hint. I will go take a look next time I get a minute to give it another try. Banjo (_)=='=~ Quote Link to comment Share on other sites More sharing options...
camorri Posted July 7, 2006 Report Share Posted July 7, 2006 Banjo, Any updates? Have you got Audacity working yet? I've been following this thread, hoping you would post a fix. I'm trying to get it working also, and no luck. I joined the Audacity forum. It seems you need to run Audacity on a lot of distros using aoss, this is a oss wrapper. I installed it on my Mandriva 2006 system, but no music yet. I can load a wave file, and soon as I press play, it crashes. All I get in the lauch window id: PaHost_WatchDogProc: cannot set watch dog priority! PaHost_WatchDogProc: killing hung audio thread! Killed This is after I launch Audacity with command 'aoss audacity' load a wave file, and press play. Sound on my system works for other apps. I disabled System Sounds. Seems Audacity can not live with that enabled on lots of systems. Well, I'll keep plugging away, hope someone out there can post success with a working config, or give us some idea on how to trouble shoot this mess...

null Posted July 7, 2006 Report Share Posted July 7, 2006 Well, here I am answering my own question again :D yeah, I had a thread about capturing video with kino and a digital camera... I was just talking to myself for several days.... but I got it fixed ... so did you get audacity fixed? I want to try it out also. Quote Link to comment Share on other sites More sharing options...
scarecrow Posted July 7, 2006 Report Share Posted July 7, 2006 This is really an old thread, but anyway... Audacity 1.2.4 runs fine here, no matter if I use ALSA or OSS, or if artsd is enabled or not. The most annoying thing about it is that it *still* does not support unicode, which is unacceptable for a modern application. Quote Link to comment Share on other sites More sharing options...
