Public bug reported: Recording applications (audacity, arecord, gnome-sound-recorder) record extremely slowly (at what seems to be 0,1x speed), which means that at playback the sound is played at a very high pitch and much faster than the original.
To help you understand the issue, I've attached an archive containing two files recorded at the same time, one with arecord -f cd and the other with a stand-alone Olympus recorder. A video of Audacity's behavior when trying to record is also available: https://youtu.be/Fe20eQNvZVA Look at the seconds hand of the xclock and how much it is moving before Audacity is done recording one second of audio. Things I've already tried: * Purging and reinstalling Audacity * Purging and reinstalling Pulseaudio following the guide on the Ubuntu Wiki * Running audacity with this command: Exec=env PULSE_LATENCY_MSEC=30 audacity as suggested on AskUbuntu * Reinstalling Ubuntu on a new hard disk * Running audacity on a live CD (in Ubuntu version 16.04.3, 17.10.1, 18.04 daily and Xubuntu 17.10.1, 18.04 daily) The machine is a Ryzen 5 1600 with an ASUS X370 Prime motherboard. The problem can be reproduced as follows: * Boot a live DVD of Ubuntu/Xubuntu 16.04.3, 17.10.1, 18.04 daily (versions I've tested with) * Install audacity via the terminal * Start recording, microphone is connected to the rear microphone jack.
