These audio messages look like warnings, not fatal errors, but I am
not sure.  I would view the VM details using virt-manager and remove
the sound card device from the VM if you don't need it.

There were no further error messages indicating that starting the VM failed?

You mentioned using QCOW2.  Use "qemu-img check
sy0005embinf02_vdb.img" to run a consistency check on the image file.
There should be no fatal errors.
