Hi One of my students want to run miniAudicle under ubuntu 9.04. I helped him compile it, but for some reason it behaves quite strange. When the VM is started it shows run time of some large number (36276252.3645 or something) and when the first shred with sound-generating a ugen connected to dac is added the mini segfaults. I never saw this behaviour before, any idea what's up? NB: Sorry for the rather imprecise error report, I only saw his machine once, about a week ago... -- Atte http://atte.dk http://modlys.dk http://virb.com/atte
That happens to me once in a while, too. Sometimes, the VM hangs for a
second, I get the Cancel/Abort dialog, and if I hit Abort it usually
just keeps going. It doesn't happen in the middle of the process,
though, which is why I'm not all that concerned. It just seems to be
an error on startup.
I know compiling for 64-bit systems, even with -arch i386 yields tons
of warnings, so it could be related to one of those. There are just
too many deprecated things to count. Does anyone have a version of the
mini for OS X in an Xcode project? Until I get it transferred to Xcode
there's no way I'm spending time debugging that, but I would love a
64-bit ChucK/mini if possible.

I saw that too, quite frequently even, to the point of me being quite annoyed by it. I believe (but this is based purely on gut feeling) that Pulse-audio (the Ubuntu default) doesn't play as nice with Alsa as it should. For me this seems related to certain applications (say Skype or a browser running Flash (or having opened it)) claiming the soundcard in ways they shouldn't. As ChucK depends on the audio drivers polling it (or so it seems to me) a malformed connection there will muck up every thing else. For me it has so far been fixed by stopping the VM, quitting all such programs, adn re-starting it. sadly this process may well crash the mini altogether. I can't point a specific finger either but something, somewhere, is wrong. Personally I suspect Pulse, but Pulse is fine with combining, say, Skype, Flash and a mp3 player. Could we be claiming the soundcard in a non-nice way under some conditions? I think I feel it's the audio system's job to notify us when something is wrong in a claim laid to it but it would be good to document exactly what claim and how, if i would be right, and how to prevent such conditions Might be a RTAudio issue? Might be something applications like Skype or Flash take to be a lowest common denominator on Linux systems? Kas.

Hmm, you might be right but: 1) I installed miniAudicle on my wifes eee running a vanilla ubuntu 9.04 and I never had a problem here. 2) He didn't have any other applications running at the time. 3) I wasn't able to successfully run the mini even a single time. Wouldn't a solution be to remove pulseaudio? I didn't hear much good about it over at linux-audio-users, many say the first thing they do upon installation is to remove pulseaudio... -- Atte http://atte.dk http://modlys.dk http://virb.com/atte
For what it's worth, the same thing happens to me on OS X 10.6 (and
earlier on 10.5) with a MacBook Pro.
