Audacity 1.3.3-Beta (Poss. Bug) - Crash after resample.

[thundergod]

I have never bug posted before, so please excuse me if I screw this up. I prepared the following last night after a crash while using audacity. Thank $deity I was able to attach GDB to the process before it popped its clogs. I hope someone can help me with this. Here goes. (Ps: If this doesn't format correctly, blame VI. I prepped it in that! )


******************************************************************************************************
Below is a backtrace from audacity 1.3.3-Beta (Unicode version)

The output was recovered when I attached GDB to Audacity Process following
the GUI of Audacity ceasing all function. (Click buttons, no playout, no record,
no meters, nada.)

Previous to this, I had been editing a track within Audacity and had just finished
a track resample from 44100Hz to 22050Hz. The resampled track would not playout.

Playout was via ALSA:FRONT

Crash occurred at 00:11 25/02/08

I'm not certain if this feature is in Audacity 1.3.3 (I use 1.3.4 in Xubuntu), but try looking in the "help" menu and see if there is a "Audio Device Info" option.

If there is, check this carefully to see what sample rates ALSA supports for your selected playback and recording devices. (I notice that with my sound card there is quite a strange selection of supported formats which vary depending on which input and output I use)

That facility I cannot see in 1.3.3 - but I do know that the device I have (Intel 82801DB Onboard) accepts 8000hz, 11025, 22050, 44100, 48000 and 96000hz for playback and record.

This one is a mystery to me Steve, we got the (unstable) 133 issued with Mandriva 2008.0 - I am at a loss as to why Mandriva would even issue an unstable beta with a working OS...

I know that my soundcard can do these too, but with ALSA I can only record at 48000 Hz on one input, 44100 Hz on another, and the whole lot on spdif (which my card has no socket for), or on any of the other inputs that have 0 channels available.

If I'm using Audacity, I have to use 48000 Hz and then it works great, but using JACK I can use any. Unfortunately Audacity causes JACK to freeze on my machine.
