Adding a virtual sound device to ESXi

Adding a virtual sound device to ESXi

2020, May 16    

While I want to stream audio and video from my Commodore 64, actually an Ultimate64, I stumbled across the absence of audio on a virtual machine running on my lab system.

Essentially I needed to manually edit the VM context.

Following this procedure: M

  • Make sure that the VM is in a powered-off state
  • Browse to the datastore where the VM resides
  • Download the .VMX file
  • Edit file by adding the undermentioned lines to the end of the file

    Startup the VM again sound.present = "true" sound.allowGuestConnectionControl = "true" sound.virtualDev = "hdaudio" sound.fileName = "-1" sound.autodetect = "true" sound.pciSlotNumber = "34"

  • Upload the file again to the same spot in the datastore

Now the VM can play audio again. In my case i can record/stream audio from my C64 to the VM.
