You need to open port 5353/udp for avahi and port 4713/tcp for pulse.

See the options listed here:

You can use anon or IP based ACL. It can also use X11 based auth but
that's not always super handy.

If this is 0.9.7 then I'm not really sure (as I wrote in my other mail),
but hopfully I misread and you're actually using the 0.9.8 from rawhide
and simply disabling the suspension of the device will work around it
and patching will fix it.
