this bug does not happen every time I record webcasting audio by audacity it happens from tome to time, server is the same
(In reply to comment #3) > this bug does not happen every time I record webcasting audio by audacity > it happens from tome to time, server is the same How are you recording the streamed audio? What source are you selecting to record from? Do you have software playthrough turned on or off in audacity? The memory map shows you have pulseaudio running - if this is being used as the audio source/sink then the problem is probably somewhere in it's emulation of ALSA, which has never been transparent. Using jack-audio-connection-kit to do the audio routing might be more robust, as it can be natively supported in Audacity. Direct downloading the stream to disk rather than playing it would be even better ... To track down the cause we will need a backtrace of the crash, or a valgrind run to locate the memory management error. This will obviously be harder if the problem is not reproducible. I wonder if the ultimate problem will turn out to be a buffer over/underflow caused by the web stream running faster or slower than PulseAudio's local clock?
please retry with 2.1.3-r1
