Hello, Tiki
Thank you for your help.
However, this improvement in functionality does not resolve my issue.
This is because it’s a problem caused by format unsupported.
The issue arises because Denon does not support 32-bit sources; Denon Home only supports PCM format up to 192k/24bit.
I am not sure if TuneBrowser can detect this problem.
I have captured packets with Wireshark and indeed, it returned a large number of RST packets.
