Proxmox Window 11 Sound

When making changes to the VM, best to have the VM off. Make the changes and boot the VM.

This took me hours to figure out, with most of the time used searching and with no avail. So I started to experiment and found the answer.

In the Proxmox PVE VM, go to Hardware and make sure that Display is set to SPICE (qxl):

ProxmoxWindows11Sound

This will activate the audio in Windows 11.

Windows11WithSound

Even though the audio is activated on Windows 11, unless the Audio output mode is set to Local on the RDP client, Windows will shows no audio.

Windows RDP client:
WindowsRDPEnable sound-RDP edit

If using Remmina:
RemminaRDP
