Hi,
Audio does not work when spicy is opened using:
lxc console win11 --type vga
However audio works with this same instance if I open spicy from cli and use this same spice socket:
spicy --uri=spice+unix:///home/mika/snap/lxd/common/config/sockets/1062376126.spice
This is probably related to some privilege issue (e.g. cannot connect to dbus) when spicy is opened from lxd snap package.
Lxc console command outputs errors like:
(spicy:1633481): dbind-WARNING **: 23:05:45.126: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
GSpice-Message: 23:05:45.182: main channel: opened
/dev/shm/jack_db-0/__db.001: No such file or directory
These errors are not shown if I open spicy from cli.

Hey,
Could you please let us know a bit more about your environment so that we can try to reproduce the issue? What’s the host OS (lsb_release -rc), kernel version (uname -a) and LXD version (snap list lxd)?
Thanks
Hi,
Certainly:
> uname -a
Linux SOLPF4F14Z4 6.5.0-35-generic #35~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue May 7 09:00:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
> lsb_release -rc
Release: 22.04
Codename: jammy
> snap list lxd

Here is a process tree view of this situation:
In the top spicy the audio works but in spicy forked from lxc process audio does not work.
This is perfectly fine but please know that latest/stable is a moving target so currently is has 5.21 which is an LTS version but when we publish a new feature release (soon), it will have your machine upgrade to a non-LTS.
In other words, please double check that you intend to be on a feature track and not the last LTS one. If you want to switch, now’s a good time, see LXD 5.21.1 LTS has been released for the exact snap refresh command to use.
Now, thanks for providing the version information, I’ll try to replicate the issue here.

One way to easily circumvent this issue is to use other spice clients than spicy or virt-viewer e.g. remmina or install them from other source than apt e.g. flathub so that lxd cannot find them.
Then you can just start your favorite spice client manually and use the socket from lxc console command output.
Maybe cli applications like lxd should not open graphical applications because this seems like a permission rabit hole which is not otherwise needed in lxd package.
