VMs becomes Aborted on start with audio enabled

[dtgeorge]

After update to 5.0.12 from 5.0.10 there are an issue: VMs has Audio enabled cannot be started and drops to Aborted state. Disabling Audio solves issue.

Each start attempt adds segfault to kern.log:

 EMT-3[2993]: segfault at 18 ip 00007f191d3f3ab8 sp 00007f1942415bd0 error 4 in VBoxDD.so[7f191d383000+27a000]

VBox.log for selected VM contains:

UPD1: this ticket is about headless virtualbox! UPD2: it starts fine when I set Host Audio Driver setting to "Null Audio Driver" value, but there are no sound (

Before I had value "Alsa Audio Driver" for that setting and it worked fine. But not with 5.0.12

alsa version:

aplay --version
aplay: version 1.0.27.2 by Jaroslav Kysela <[email protected]>

Same problem as #14942.

May be related to #14981.

Should be fixed in VBox 5.0.14.
