pavucontrol would normally work as you expect except it seems your qemu
configuration is using the USB sound card exclusively, preventing pulse
from using it - unless real-time latency is a high concern, there of
no noticeable benefit of pass-through for a sound card

this also would normally work as you expect if you let qemu handle the
sound output - that becomes simply another pulse client on the host
(if that's your thing)

or, more simply, remove the pass-through and let qemu "just work" by

or, for more sophisticated needs, use the net-device features of pulse
(or JACK, if low-latency is a concern)
