@MrDenis ----- Thank you for chiming in here and sharing your experience with us. The feedback is appreciated. To help me properly evaluate this behavior, can you please provide me with the following information:

  1. An expanded description of your setup as seen here.

  2. Please provide the details of your network configuration/topology, as well as providing insight into any networking hardware you may be implementing. I want to have a complete understanding of what the chain of communication looks like in your setup.

  3. I know from another report that you are accessing your musical collection off of a Drobo NAS. In your troubleshooting of this issue did you try playing any locally stored content on your core machine? If so, was the experience the same or different?
