I've started looking at that. Using either 48k or 44.1 depending on spice-server is easy. The annoying issue is when the server/qemu agreed to use 48k internally, but a client only supporting celt tries to connect, then you need to do some resampling, and this means we need a bit of refactoring of the existing code to get this to work.
