Cannot cast to Google nest.

[nemasu]

Hello,

I am unable to cast from Chrome to my Google nest speakers. It still works fine from my phone or another machine on the network, but it's not working from any guest VMs.
The error I get from my Windows guest VMs is "casting tab audio is not supported on this device".
Here's my networking configuration:

auto lo
iface lo inet loopback

iface enx84afec73d6ec inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.10/24
        gateway 192.168.1.1
        bridge_ports enx84afec73d6ec
        bridge_stp off
        bridge_fd 0

Is there something I need to do to get multicast working properly between guest VMs and other devices on the network?

Thanks

Hey,

do you run the same OS in the VMs as on the other machines in your network?

Hi, yup everything is Windows 10, except for the Proxmox host.

Did you take look at https://pve.proxmox.com/wiki/Multicast_notes? You could try the things mentioned here https://appuals.com/fix-casting-system-audio-is-not-supported-on-this-device/.

Yeah, I tried a few of those things, like

  post-up ( echo 1 > /sys/devices/virtual/net/$IFACE/bridge/multicast_querier )

I also tried "Re-Enabling the media Router" in the 2nd link.
The rest seem irrelevant, as it works just fine using the same set up but using a machine on the network instead of a VM.

Edit: I tried this instead too:

post-up ( echo 1 > /sys/devices/virtual/net/$IFACE/bridge/multicast_querier )
post-up ( echo 0 > /sys/class/net/$IFACE/bridge/multicast_snooping )

Thought for sure that would have worked, guess not.
