Audio canceled strangely with virtualbox grater than 5.2.18.

The problem

Starting with virtualbox 5.2.20, the audio began to not work properly for me. When I try to play some audio, I hear the first part of the audio, but it is cut of a short time before the end. So, if I for example try to play a file containing the words "Hello World!", I may only hear "Hello Wo". If I then try to replay the file, it works exactly as previously: I only hear the first part of the file. It works with virtualbox 5.2.18, but not with 5.2.20 or later, so the bug was introduced with the 5.2.20 release.

System

I am running windows 7 as host and headless arch linux as guest. I am using alsa as sound server on the guest.

Attachments

I will attach VBox.log and a webm file where I try to play audio. The webm file is recorded video from the guest. I try to create a file containing "Hello world!", called hello.wav, with espeak. Then I try to play the file with aplay, both in userspace and as root. Audio is included so you can hear the result.

Priority

This bug is very critical for me. I am blind and therefore I am partially using speech to access the screen content.

Thanks in advance!

The webm (video) file was too large. So I will attach this link where you can download it instead. ​https://drive.google.com/open?id=1jo5Yn0GJ7qTliuB46srIWZCse71t6TK-
