Denon AVR-4520CI Audio Issues
My AVR-4520ci began having some audio issues today and I am hoping the group can help shed some light on it for me.
Here is a video I took if it is helpful:
**Since this is my first forum post, it would not let me post a link but on YouTube it is available under username klausflouride1 video name "Denon 4520ci Sound Issue."
There is no sound when set to AT&T Uverse, Blu-ray, Internet Radio, Spotify, and Apple TV but I do get audio when playing CDs (not shown in video). CDs (Marantz SA-11S3) play just fine in Zone 1 and Zone 3 so I don’t think it is an issue with my amp (Parasound A-31). Please notice in the video that when set to UVerse the speaker lights flash on and off. I tried updating the firmware and have reseated the HDMI cable to the UVerse box. When I turn the volume up when set to UVerse, Blu-ray, Apple TV, and Internet Radio/Spotify there is a fairly rapid thumping sound coming from my speakers. Any help with this would be greatly appreciated. If I should take it in to the local authorized Denon service center please let me know. Seems like every source connected via HDMI is not playing sound (although the Oppo BDP-105 only passes video over HDMI - audio is passed via the discreet 7.1 audio outputs into the Denon).
Thanks in advance,
