I found out that if I change the refresh rate in : Settings / Display / Refresh Rate from 60 to 59.94, the screen blinks and the sound is back - but once I enter suspend and back on again, there's no sound.

After a week dealing with this issue, I'm pretty sure my problem is with the NUC's resume from suspend and not a timing issue at all. I tried reaching out to Intel Tech Support but they shut me down saying my NUC is now obsolete and there is no further support. I wonder if the HDMI handshake waking from suspend is the same as a power on or reboot. I cannot power my NUC on from a full power down unless I press the NUC's power button. There is no remote control support for power on from this old NUC.
I'm now shopping for NUC8i3BEK (2018 model) to replace my much older 2013 i5 NUC. I'll gain 4K support and the no sound issue should be fixed.

Thanks but I tried that earlier in this thread. It didn't work for me.
-
I turned on my TV and Receiver. About 10 seconds later I turned on my Intel NUC. No sound again.
-
I will try turning on the TV and Receiver and then the NUC last. If that fixes the issue, I will try adding a 1 to 3 second delay to the NUC resuming from suspend using my Harmony 650 remote. Thanks for the suggestion. I will update this thread.
By the way, I tried both my Intel NUC's and they both have this same exact issue with my new Yamaha Receiver.

Update: I found a work-around tonight. If I start my system in TV mode (Verizon Cable Box) and then switch to Kodi which wakes my Intel NUC from suspend, the sound works every time. I'm guessing the TV mode completes the hdmi handshake and EDID, which the new receiver remembers until it's shut off. I can switch between Verizon TV & my NUC and the sound remains, even though the NUC goes into SUSPEND when the TV mode is on.
My guess is that the NUC's hdmi handshake / EDID signal or whatever is much stronger during POWER ON, than it is resuming from SUSPEND and that the new Yamaha Receiver is more sensitive to this. Maybe if I had chosen another brand of receiver, like Denon, I might not have this problem at all.

I struck out today. I tried a new cable, different hdmi input, an hdmi audio splitter and a custom EDID. None fixed my problem. Now I'm wondering if I should return the new Yamaha Receiver for another brand.

I used PuTTY and ran the command getedid create. It rebooted my NUC in 15 seconds but unfortunately it did not solve the no audio problem. I followed the directions to the T.
I am trying new hdmi cables, inputs and the hdmi audio splitter later today.
Thanks

It's been a while since I SSH'd into Kodi. I enabled SSH in Libreelec and launched FileZilla. I input the host, username and password and it's connected. Now what ? Where do I type the commands ?

Have you already tried a Custom EDID?
Actually, I just finished my phone call with Yamaha Tech Support and the guy was very knowledgeable. He said it does sound like an EDID issue. I don't know anything at all about EDID, so any help would be greatly appreciated. In the meantime I am going to try a new HDMI cable, another HDMI input and then as Da Flex suggested - an HDMI Audio Splitter. I'll click the link supplied for Custom EDID above.

I actually have an HDMI Audio Splitter packed away somewhere. I'll have to give it a try. Thanks !

My new Yamaha Receiver allows you to switch between HDMI 1.4 and 2.2 for each HDMI input. I crossed my fingers and selected 1.4 for the NUC and the problem still exists. Oh well. I'm in a phone queue waiting for a return call from Yamaha Tech Assistance.

Update: I connected my Intel NUC directly to my Sony TV (2009) using an HDMI cable. I then connected my Sony TV's Digital Audio output to my Yamaha Receiver. This fixed the HDMI handshake problem BUT I cannot leave it this way because of two new problems. First, the video is over-saturated with both contrast and color. And secondly (most important), my Sony TV does NOT pass HD Audio of any type. I guess the TV is just too darn old to handle HD Audio.
I really don't want to buy a new Intel NUC and TV at this time. I'm going to call Yamaha Tech Support to see if they have a fix. Rebooting the NUC every time I want to use it is frustrating and a little time consuming.
-
I'm not sure if my old Sony TV will pass HD Audio through it's optical output connector. I guess I could give it a try.
-
Could you describe your HDMI cabling please?
If it's NUC -> receiver -> TV, then your new receiver might block (don't update) HDMI communication after suspend.
Yes, the cabling is as you show. My 2009 Yamaha Receiver did not have this problem. My brand new 2019 Yamaha Receiver (same basic specs) has this problem. It's definitely an HDMI issue but I'm clueless as to how to fix it. For the meantime, I will reboot my NUC every time I use it.

My previous setup worked fine but with this new Yamaha Receiver there is no audio unless I reboot my old Intel NUC.
Intel NUC DC53427HYE (3rd gen i5)
Yamaha RX-V765 (old receiver)
Yamaha RX-A780 (new receiver)
Sony KDL-46XBR6 TV (2009 model)
LE 9.2.0
I use Wake from Suspend on my NUC because this model NUC doesn't support remote POWER ON. When waking from suspend, there is no audio and under Audio Settings I see this:
ALSA: HDA Intel PCH, HDMI #0
After a reboot of my NUC, I have sound again and see this:
ALSA: HDA Intel PCH, SNY Sony TV XV on HDMI #0
Any idea on what I can do to fix this problem ?
Problem Fixed ! See posts #28 to 35. (thanks to mglae)
