I am playing with audio and I know that the syntax has changed.

I have a NetBSD 9.2/amd64 guest that I have tried launching like this:

#!/bin/sh
/home/oc/git/qemu/build/qemu-system-x86_64 \
-drive if=virtio,file=/home/oc/VM/img/netbsd.image,index=0,media=disk \
-drive if=virtio,file=/home/oc/VM/img/netbsd.image.old,index=1,media=disk \
-M q35,accel=kvm -m 500M -cpu host -smp $(nproc) \
-nic user,hostfwd=tcp:127.0.0.1:5555-:22,model=virtio-net-pci,ipv6=off  \
 -device intel-hda -device hda-duplex \
-serial mon:telnet:127.0.0.1:6665,server,nowait \
-pidfile /home/oc/VM/pid/netbsd-pid

See the " -device intel-hda -device hda-duplex " line? I am not sure
if this is enough, but I can see the audio device in the guest:

dmesg|grep -i audio

I have also tried the old syntax:

-soundhw all

With similar output in dmesg but no audio forwarded to host.

Any help will be appreciated.
