Finally got our music system stabilized for reliable operation and thought I'd share a few notes in case useful for others. This is a wired DLNA system with MC 20 running on a MiniMac and music stored on a Synology DS214Play NAS. All files are FLAC with a mix of CD and HD resolutions. Three rooms use NAD 7050 and three rooms use Cambridge Audio StreamMagic6 for rendering. The three rooms with CA boxes also have TV's connected via Ethernet. One of the NAD's is connected to the MiniMac via USB (using the NAD driver), while the others are connected via Ethernet. Remote control is via Gizmo on an Android phone and JRemote on iPhone and iPad. Remote equipment control is via RTI from the iPhone and iPad (I still can't get the Android phone to reliably connect to RTI).
1. Application Conflicts: One of the first things we had to do was deconflict multiple applications trying to play the same role (e.g. DLNA server). These have been widely addressed elsewhere in this forum so I'll skip the details here.
2. Auto-Start: We had MC being auto-started twice and two copies running conflicted with each other. This problem was also solved through help from this forum.
3. Power Saving Features: I ended up turning these off for the Synology DS214Play NAS, MiniMac, and Dell Monitor. Seemed to have problems occasionally when components went to sleep. Maybe out-of-sequence wake ups among components causing problems.The power amps still sleep, but these don't seem to interfere with operations.
4. TV and Music Networking: Organizing the TV Ethernet connections onto one Switch and running music through another helped improve reliability. Even with a Gigabit LAN and good NetGear switches, we were experiencing loading issues when multiple rooms ran concurrently. The networking aspects are well beyond my comprehension - recommend hiring a good professional. One issues was that the AT7T U-verse guy would come and change things around to optimize performance for TV's, then my networking guy would have to change it back to balance network performance for TV and music systems.
5. DLNA Controller Settings: The NAD and CA renderers each require different DLNA Controller Option settings within MC. I disabled SetNext Support for all rooms (on advice from this forum). For the NAD 7050 rooms, I also set MC to "Ignore Transport Events". The combination of these two settings solved a strange problem with the NAD's where the first song would play fine, then every subsequent song would be highly distorted. This configuration of DLNA Controller Settings was also recommended by the engineers at NAD. However, turning on Ignore Transport Events broke the CA StreamMagic6 renderers. They would stop playing after one song. So I had to turn it off for those rooms.
6. Remote Control Connections: While the music components are connected via wired Ethernet, the handheld remotes (iPhone, iPad, Android) are connected via WiFi. There are multiple WiFi access points throughout the house to get good signal strength throughout. We had several problems with handoffs among access points as we moved around the house controlling music in different rooms. Upgraded the WiFi system to one that has built-in handoff features among access points, which helped. Still have a few problems with this, but most of the time it can be fixed by manually forcing the handheld to remote to reconnect to MC. The iPhone still gets confused sometimes trying to reconnect to the old PC that had MC on it before I switched to the MiniMac. May need to reinstall JRemote to make it forget the old PC.
Thanks for all the help from this forum.
