I'm afraid not; it's still on my list to look at at
some point, but I've been focusing mostly on stuff

Hi,
I'm using qemu-system-x86_64 with the following options:
-audiodev pa,id=sound1,server=/run/user/1000/pulse/native \
-soundhw hda
After upgrade to 4.2.0 (qemu-4.2.0-7.fc32) I get the following warning:
(qemu) audio: Device hda: audiodev default parameter is deprecated, please
specify audiodev
