I'm running Ubuntu 16.04 on a virtual machine (2 GB RAM, 12 MB video memory) in VirtualBox 5.1. The host OS is macOS Sierra 10.12.5.

Whenever I play a sound on Audacity, the output sound is garbled and glitchy for a short while and the playhead jumps a couple of seconds ahead. The sound plays normally after that.

I tried reinstalling Audacity from Ubuntu Software. I also tried installing Audacity from the PPA. But the problem persists.

I'm experiencing similar issues with other apps as well. For example, in TuxGuitar, the position of the playhead and the actual note being played are not in sync.

Does anyone know a way to solve this problem? I would really appreciate any help.

I had the same problem with Ubuntu 18.04, Audacity 2.1.1 and VirtualBox.

I found that by changing Audacity's playback device to "sysdefault" the scratching and jumping goes away.
