[Regression] v9.1.1: hw/audio/hda audio output stream closes (SPICE)

Description of problem
Beginning with QEMU 9.1.1, SPICE is unable to route audio from the guest to host. This affects virt-viewer as well as Looking Glass. Reverting packages to 9.1.0 restores functionality.
Reported at Arch Linux forums and Looking Glass discord
I've confirmed 6d03242a caused the regression, applying reverse patch to 9.1.1 resolves the issue
