@ -796,11 +796,18 @@ Supported audio devices are:
* `intel-hda`: Intel HD Audio Controller, emulates ICH6
* `AC97`: Audio Codec '97, useful for older operating systems like Windows XP
NOTE: The audio device works only in combination with SPICE. Remote protocols
like Microsoft's RDP have options to play sound. To use the physical audio
device of the host use device passthrough (see
xref:qm_pci_passthrough[PCI Passthrough] and
xref:qm_usb_passthrough[USB Passthrough]).
There are two backends available:
* 'spice'
* 'none'
The 'spice' backend can be used in combination with xref:qm_display[SPICE] while
the 'none' backend can be useful if an audio device is needed in the VM for some
software to work. To use the physical audio device of the host use device
passthrough (see xref:qm_pci_passthrough[PCI Passthrough] and
xref:qm_usb_passthrough[USB Passthrough]). Remote protocols like Microsoft’s RDP
have options to play sound.
