Running ESXi 5.1 update1a
I found a "hack" online where if you edit the VMX file of a VM and add in these lines, then re-upload the vmx file and boot the VM, an "HD Audio" device shows up in the VM hardware and windows recognizes it as a soundcard.
sound.present = "true"
sound.allowGuestConnectionControl = "false"
sound.virtualDev = "hdaudio"
sound.fileName = "-1"
sound.autodetect = "true"
sound.pciSlotNumber = "35"
If I attempt to migrate it to another host or datastore I get a validation error:
VM is configured to use a device that prevents the operation: Device 'HD Audio' has a backing type that is not supported. this is a general limitation of the virtual machine's compatibility with the ESXi version of the selected host.
Therefore the only way to migrate it is cold. I was wondering if VMware has a first party ability to add a sound card to a VM or if anyone knows any other workarounds for this?
Thanks
