Steve wrote by email: An alternative workaround for bug 276 appears to be to set the output device to "dmix". I've been testing this for the past couple of days, and no freezes when using dmix.
The advantage of dmix over "hw:" is that the vast majority of sound cards do not have hardware mixing, so when the "hw:" device is used, only one application can use it at a time. On the other hand, dmix is a plug-in for ALSA that provides mixing, so multiple applications can use the sound card simultaneously. The downside of dmix compared to the "hw:" device is that not all distros install it by default (though I think that most do). The downside of dmix compared to PulseAudio is that it does not support recording what is playing on the computer. PulseAudio would be the best device to use if it were not for bug 276 (and it is the default for most modern Linux desktops).

I connect my earphones to the mic and use it for hearing both my own voice live and the computer sound (I have to select it in Ubuntu's sound output settings). This works fine for a while, and I can record and play back through the mic. Seemingly randomly, however, pressing play or otherwise trying to start playback sometimes makes Audacity skim quickly through the audio, playing garbled sounds which I assume are a fast forward version of my audio. Sometimes, it resumes normal playback before it reaches the end of the file, and everything seems fine. Most often, though, it does not, and pressing the stop button or anything else crashes Audacity. If I restart Audacity and restore the autosaved audio, the problem persists. However, selecting another audio output in Ubuntu's sound settings fixes the problem. I recently upgraded to Ubuntu 15.10, but this has been a problem since at least 15.04. I now use Audacity 2.0.6-2build1.
