Essentially i needed to manually edit the VM context. Following this procedure:
- Make sure that the VM is in a powered off state
- Browse to the data store where the VM resides
- Download the
- Edit file by adding the undermentioned lines to the end of the file
- Upload the file again to the same spot in the data store
- Start up the VM again
sound.present = "true" sound.allowGuestConnectionControl = "true" sound.virtualDev = "hdaudio" sound.fileName = "-1" sound.autodetect = "true" sound.pciSlotNumber = "34"
Now the VM is able to play audio and in my case also record/stream audio to my Twitch channel.
