Description Of Issue
Very new to Roon; currently at the beginning of my trial period, and initial impressions are that I am in love with everything that Roon offers, and I’m entirely frustrated with my experience so far. Initial setup of Roon server was painless via Easy Installer. Configuration of zones/audio devices except for Chromecast devices has been painless. Streaming directly to the Hegel via Airplay works great, streaming to my iPhone and to the desktop app work great, but both enabling and streaming to any of the Chromecast devices or cast groups has been an absolute nightmare. When I’m able to get the devices enabled, playback works for approximately 3-5 seconds and then cuts out… every… single… time.
In any case, here is a sample from the logs when attempting to enable a Chromecast device as a Roon endpoint (Chromecast Audio, v1.42.172094):
10/21 11:38:03 Error: [cast/client] [CastReceiverChannel] Failure to start application 6242A3BE on device: {
"reason": "CANCELLED",
"requestId": 953,
"type": "LAUNCH_ERROR"
}
10/21 11:38:03 Error: [cast/client] [Chromecast-Audio-8230aa5b68bd1dd2b236f4a6e9a42029._googlecast._tcp.local] Failure to start Roon App on device
I experience the same issues both enabling and casting to the Nest Audio speakers and cast groups in our home. I have restarted the Roon service, as well as the entire server, as well as the Chromecast Audio. I have disabled the firewall on the box. This is a multi-function server with 32GB of RAM. Home Assistant and a few additional Python microservices I’ve written have no issues connecting to or maintaining connections to the cast receivers, so I am confident that networking and the network topology is not an issue here. All devices are on the same subnet. I do have a box of Google Ethernet Adapters for the CCA, so I can utilize one if you’d like, although I experience the issue on all of the cast receivers and groups I’ve tested with.
Thanks,
William
