Audio/video problem - linux guest on OSX

[Beans3]

I have a problem with playing audio/video in Linux mint 19.2. i have to keep resetting my audio with this command:

[quote]sudo alsa force-reload[/quote]

But after I reload the problem quickly recurs.

Some information about my system:

• Host: OS X Mojave 10.14.3
  Guest: Distro: Linux Mint 19.1 Tessa base: Ubuntu 18.04 bion
  Guest Additions: 5.2.26
  Virtualbox version: 5.2.6 r128414 (Qt5.6.3)

I think it may be due to a virtualbox graphics adapter driver - InnoTek Systemberatung GmbH: VirtualBox Graphics Adapter - because when I try to update it via Device Manager I am met with the following error message:

[quote]Package dependencies cannot be resolved

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

The following packages have unmet dependencies:

virtualbox-guest-x11: Depends: virtualbox-guest-utils (= 5.2.18-dfsg-2~ubuntu18.04.3) but 5.2.18-dfsg-2~ubuntu18.04.3 is to be installed
                      Depends: libxcomposite1 (>= 1:0.3-1) but 1:0.4.4-2 is to be installed
                      Depends: libxdamage1 (>= 1:1.1) but 1:1.1.4-3 is to be installed
                      Depends: xorg-video-abi-23 but it is a virtual package
                      Depends: xserver-xorg-core (>= 2:1.18.99.901) but 2:1.19.6-1ubuntu4.2 is to be installed

When I run sudo apt-get install on any of the dependencies above it reports no need to upgrade, eg

[quote]$ sudo apt-get install  libxcomposite1
Reading package lists... Done

libxcomposite1 is already the newest version (1:0.4.4-2).
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

beans7@beans7-VirtualBox:~$ sudo apt-get install xorg-video-abi-23

Note, selecting 'xserver-xorg-core' instead of 'xorg-video-abi-23'
xserver-xorg-core is already the newest version (2:1.19.6-1ubuntu4.2).
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.[/quote]
