Hello!
I still have a problem with ZONE2.
In some situations I cannot send audio to the headphone amplifier connected to the Denon ZONE2.
In the settings of the DENON X3500H I set HDMI audio in "PCM".
When the source is the bluray UHD player everything works correctly: I can send the audio to the headphone amplifier.
1. if the source is the TV, I cannot send the audio to the headphone amplifier. The TV is connected to the DENON X3500H with an HDMI cable. The HDMI port of the TV (LG B9) has the "ARC" function. I solved it by connecting an optical toslink cable between the TV and the DENON and setting the optical audio source in ZONE2. Can I solve the problem without connecting the optical cable?
2. I connected a PC to Denon. I can't in any way send the sound from ZONE2. In the windows settings I set stereo audio. How can I solve with the PC?
