UDP socket timed out, the app is not receiving audio data packets

Hello there! I’m trying to play audio from my Windows virtual machine on Proxmox, it successfully connected but no audio data is received.

  • The firewall is disabled both on the Windows virtual machine and Proxmox.
  • I’m connecting to the virtual machine via Ethernet, with traffic route to 192.168.2.2 which is the Proxmox host (then to the virtual machine).
  • On windows, connecting AudioRelay to 127.0.0.1 does receive audio data normally. Indicated by the latency display.
