Question: Airplay connection problems from iMac
My Marantz stereo is connected to my home network. It has Airplay enabled.
I can stream music to the Marantx from my iPhone, iPad, Apple TV or from my iMac. Every now and then I have to restart the devices. Apart from that I have had no issues with this.
Suddenly, from one day to another, without doing any updates or any changes to anything on my network, I can no longer stream music from my iMac to the Marantz.
I have of course rebooted everything, including my router. I can still without any problems, stream music to the Marantz from the iPhone, iPad or AppleTV. The Marantz shows up as an available Airplay speaker in iTunes om my iMac. If I shut down the Marantz, it disappeared from the Airplay speakers list in iTunes.And when I reboot the Marantz, it shows up again. The Marantz is having no network problems. I can use internet radio on it etc.
But when I try to connect the iMac to the Marantz, I get an error message saying "An error occurred when connecting to the Airplay unit Marantz. AN unknown error 20".
Any suggestions for further troubleshooting?
