By sleep I mean screen off, the mac is still running and it sometimes responds to transport controls sometimes does not.
I have my server a synology NAS and my IMac on fixed IP’s The Imac is shown as the active interface.
The media network summary shows 3 Media Renderers, I am using a network speaker (yamaha sound bar ysp-5100) on a fixed IP as the player but it is not in the summary although it is listed on the remote as a zone player and shows up under playing now in the tree.
Sometimes using JRemote on my ipad when the imac screen is off I can select to play an album and it will wake the yamaha speaker and play and I can change track and volume, the Imac screen remains off. Sometimes the yamaha is not in the zone list and if I manually power it on it appears and I can play a track. Sometimes the Yamaha is showing and if I put the imac screen to sleep I can’t play anything.
I can’t get a grip on why everything works one minute and then not. Imac NAS and speaker all on fixed IPs.......??
All my devices are cable only ipad is wifi.
