Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Linksys wrt 1900 ac router connected to LG tv via ethernet
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
Chromecast end point on LG TV w/ optical connection to new Topping D90 DAC DAC is connected to NAD 375 BEE with rca connects.
Description Of Issue
DAC IS receiving 48KHZ signal from LG tv optical connection, but is not sending any audio to connect NAD amplfier. Identical setup to NAD internal DAC works fine.
To narrow down the issue at hand I would recommend temporarily streaming music through another app to this endpoint and let me know if it works! Based on what you’ve said, it sounds like Roon is working as expected, so we should eliminate the possibility that this is an issue with setup.
