libvirtError with pipewire audio backend

Hi everyone, I'm having trouble regarding using the pipewire backend for libvirt. My OS is GNU Guix with Wayland and pipewire running with wireplumber on a user session. I have the following versions: libvirt-9.10.0 (with pipewire enabled) qemu-8.2.2 (with pipewire enabled) libpipewire-1.0.3 I only modified the =<audio>= configuration in the xml file using =sudo virsh edit win10= as follows:     <audio id='1' type='pipewire' runtimeDir='/run/user/1000'/> I can confirm that pipewire is running and that I have pipewire sockets in the directory specified. But when running the VM using virt-manager, I get the following error:     Error starting domain: internal error: process exited while connecting to monitor: 2024-09-17T05:54:03.785811Z qemu-system-x86_64: Failed to initialize PW context     Traceback (most recent call last):       File "/gnu/store/nxpr6npj618pqmlanqqh7ks9a92jgm98-virt-manager-4.1.0/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper         callback(asyncjob, *args, **kwargs)       File "/gnu/store/nxpr6npj618pqmlanqqh7ks9a92jgm98-virt-manager-4.1.0/share/virt-manager/virtManager/asyncjob.py", line 108, in tmpcb         callback(*args, **kwargs)       File "/gnu/store/nxpr6npj618pqmlanqqh7ks9a92jgm98-virt-manager-4.1.0/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn         ret = fn(self, *args, **kwargs)       File "/gnu/store/nxpr6npj618pqmlanqqh7ks9a92jgm98-virt-manager-4.1.0/share/virt-manager/virtManager/object/domain.py", line 1402, in startup         self._backend.create()       File "/gnu/store/yaqxaja0ckyf6fm7gnd9iqlrijz6qcqy-python-libvirt-10.6.0/lib/python3.10/site-packages/libvirt.py", line 1362, in create         raise libvirtError('virDomainCreate() failed')      libvirt.libvirtError: internal error: process exited while connecting to monitor: 2024-09-17T05:54:03.785811Z qemu-system-x86_64: Failed to initialize PW context If I switch the audio backend back to =spice=, the VM will run but there's no sound. I am not sure if this is a virt-manager problem or I somehow misconfigured libvirt. How should I proceed about this problem?
