Raspberry Pi Forums

Hello,

I have recently bought a Denon AVR-3313 and when trying to plug my OpenElec-powered Raspberry Pi on it, I get HDMI sync issues (the screen flickers each time I move in the menu, and when looking at "tvservice -M" to monitor HDMI events, it tells me that the Raspberry Pi sees the HDMI link flap.

I have tried lots of different things to solve this issue without success:
- I have used another Raspberry Pi hardware
- I have tried changing the "config_hdmi_boost" value up to 9
- I have tried using a freshly installed OpenElec 3.0 version
- I have tried changing the Raspberry Pi power supply
- I have tried changing the HDMI cables

What's very strange about my issue is that when plugging in my Raspberry Pi to the front AUX1 port, it works perfectly, but when plugging it to the MEDIA SERVER port on the back (or any other port on the back, for that matter), I get the issue.

Thinking it might be an issue with the amplifier, I have also changed my Denon AVR-3313 unit, but I still get the same issue with my new unit.

Any thoughts? Anyone with the same setup as I have?

Thanks a lot for your help!

On my 3312 I had to turn off upscaling on the avr and put config_hdmi_boost=4 in config.txt I think the upscaling was causing most of the problem

Thanks for your response Dilligaf. I have turned off upscaling and have tried putting config_hdmi_boost=4 in my config.txt, but still no luck.

Here are the logs that I see using tvservice:

openelec:~ # tvservice -M
Starting to monitor for HDMI events
HDMI cable is unplugged
HDMI in standby mode
HDMI cable is unplugged
HDMI in standby mode
HDMI cable is unplugged
HDMI in standby mode
HDMI cable is unplugged
HDMI in standby mode

It goes on and on, until at some point the image stabilizes. Whenever I click a button to change the menu in XBMC, it starts flapping again.

Is there anyone on this forum using an AVR-3313 without any issue?

Thanks,
Vincent

You want to use force HDMI hotplug setting in config.txt

Hi Gordon,
I forgot to mention that I tried this as well. The result is the Raspberry no longer sees the flapping but the screen is still black.

Yesterday I tried OpenElec 3.1.7 as well as raspbmc without success. What's interesting though is that raspbmc showed no problem while in the installer (text mode) but then exhibited the problem after XBMC started.

I'd love to hear if someone has a working setup with an AVR-3313 so that we could share the differences to find out where the issue comes from...
