These are likely to be long standing P2 issues. We may be able to address them by 'workarounds' in our code, i.e. by using portaudio differently. This particular bug could be eliminated by keeping the sound card open all the time from once it is first open, and instead enabling/disabling playback and recording by switching in and out different audio callbacks. This solution would benefit all sound systems. It eliminates clicks on start/stop, facilitates monitoring when not recording (the sound card is of course open when monitoring), and has the advantage on Linux that ports remain visible and routable via Jack even when they are stopped.

The bug can (and on my machine frequently does) occur during normal use. As Pulse is the default sound system for most modern distributions, and Audacity is not usable for important work with Pulse (too unreliable), I think this bug well deserves the P2 priority. Re. comment 2, keeping the ports open would be a great benefit for Jack users.

Of course this depends on the distros accepting that change, and we could argue whether the value should be "30" or something else, but "30" solves the problems about 80% of the time. The "30" value solves another problem noted in the release notes but not in the bug title (that playback can skip through at many times normal speed).

[Ubuntustudio-bugs] [Bug 1530365] Re: Audacity plays too fast and crashes
I added upstream bug and edited the bug title to reflect that it isn't related to that specific microphone but a bug in Audacity (or PortAudio...). >From the release notes here: http://wiki.audacityteam.org/wiki/Release_Notes_2.1.2 #Miscellaneous_platform-specific_issues >A playback or recording freeze, recording dropouts or fast playback may occur when using PulseAudio. Freezes may be caused by repeatedly starting and stopping playback or recording in quick succession (or by holding down the Play or Record button). Workarounds: Try launching Audacity from the terminal with the pulse latency set to 30 ms in an environment variable: env PULSE_LATENCY_MSEC=30 audacity If you get underruns noted in the terminal, try a higher number in the PULSE_LATENCY_MSEC command. If the problem is unchanged, try a lower number. Alternatively, bypass pulseaudio by setting the playback and recording device to an ALSA (hw) choice in Device Toolbar -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to audacity in Ubuntu.
