Virtual Machine: failed to start, internal error: unable to find audio backend for sound device

I had setup three VMs under Virtual Machine: 1 Linux, Windows 10 and Windows 11. All three worked fine. Then I upgraded to Fedora 35. Now the Linux and Windows 10 systems are fine, but Windows 11 give me this error when I attempt to start it:

failed to start
internal error: unable to find audio backend for sound device

The details are:

Error starting domain: internal error: unable to find audio backend for sound device

Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 65, in cb_wrapper

raise libvirtError('virDomainCreate() failed')
libvirt.libvirtError: internal error: unable to find audio backend for sound device

In attempting to search for solutions, there isn't an exact match to the error but it seems to be a problem with libvirt but it's curious it's just with the Windows 11 VM and the others are fine.

Any ideas?
