Enable audio in LXD Virtual Machine

LXD
1

Hello all guys!
I have a vm instance with windows 10 and I am trying to configure the audio.
I am very satisfied with the performance of LXD on virtual machines, an excellent job from the development team.
I imagine that the variable to mount intel HD audio is equal to -soundhw hda in the yaml file of the profile of my vm instance.
I don’t know the correct syntax to mount -soundhw hda in my virtual machine, I hope you can help me.

My settings

config:
raw.apparmor: /home/** rwk,
raw.qemu: -drive file=/home/dennis/VMLXD/win10.iso,index=0,media=cdrom,if=ide -drive file=/home/dennis/VMLXD/virtio-win-0.1.185.iso,index=1,media=cdrom,if=ide

Adding -soundhw hda to raw.qemu should work.

try to use that variable, but it reports the following error

Looks like you attached the soundhw=hda option to the virtual CD drive. I believe it should be separate.

I tried all options.
raw.qemu: soundhw=hda,
raw.qemu: -soundhw=hda
raw.qemu: -soundhw hda,
raw.qemu: soundhw hda

where will i be failing?

Your existing raw.qemu has two -drive directives, separated by spaces. You would need to add a new directive, separated with spaces.

raw.qemu: -drive file=/home/dennis/VMLXD/win10.iso,index=0,media=cdrom,if=ide -drive file=/home/dennis/VMLXD/virtio-win-0.1.185.iso,index=1,media=cdrom,if=ide -soundhw hda

which of all these variables is correct?
raw.qemu: -device soundhw=hda
raw.qemu: soundhw=hda
raw.qemu: -device intel-hda
I have removed the options they have from the Live CD, I only have the audio montage
My setup
config:
raw.apparmor: /home/** rwk,
raw.qemu: -device soundhw=hda

stgraber@castiana:~$ lxc config set win10 raw.qemu -- "-device intel-hda -device hda-duplex"

Hi, Thank you for the solution. It does solve the problem. However getting the below error frequently and the audio stops playing in the VM.

dev/shm/jack_db-0/__db.001: No such file or directory
(remote-viewer:20659): GSpice-WARNING **: 23:11:29.077: playback: ignoring volume change on audiosink
(remote-viewer:20659): GSpice-WARNING **: 23:11:29.077: playback: ignoring mute change on audiosink

Any assistance would be appreciated! Thank you!
