I’m using Audacity for different audio cutting tasks on Debian Testing with PulseAudio. Some month ago everything worked perfectly. Several month before that it did not work at all.
Currently when I play an audio snippet, it’s playing incredibly fast and Audacity crashes. The current solution seems to be this:
env PULSE_LATENCY_MSEC=30 audacity
Use this command to launch Audacity from your terminal and it will work.
