Something to add:
I always leave my NUC on, but turn the Denon receiver and tv off.
Now I just turned on my receiver and tv and... I had no sound at all. To be more specific, I had NO audio device! Only headphones were selectable. I had to reboot to get my sound device back.
It hurts to see my five year old AMD htpc is working fine (except it's too slow now).
Any driver / bios updates coming to resolve this issue?
I am sorry to hear that have had issues with your NUC computer and AVR connections.
Similar problem was reported previously and the Intel engineering department is currently working to get this issue resolved. I still do not have an estimate time of resolution but you I recommend checking the following URL for more information:
Allan, thank you for your quick response!
I read the thread, and I just updated my bios version again to the latest v 24.
Also I reinstalled the Realtec driver and software, as I had removed these.
In the Windows device manager, the previously listed HDMI audio device 'changed' into the Realtec High Definition Audio. And I was unable to update the driver automatically, it was stuck at a 2010 driver....
Now, I have two audio devices in the Win7 mixer: Speakers (Realtec High definition audio) ánd DENON-AVR.
When I select the Speakers option, there is no sound at all. With the Denon, I have sound but only 3.0 sound. The subwoofer is silent.
The Realtec tool only shows stereo output, and mono inputs no matter what I do. No matter if I select my Denon or the Speaker option in the mixer.
By the way: The Speaker option only shows 3.5" jack in the Windows mixer panel...
I hope this info helps!
Disable the Realtek audio device in the EFI if you don't intend on using it. It is only for the 3.5" stereo jack. As far as the HDMI audio with your Denon is concerned, there seems to be many users encounterning many issues with it. Did you select the Denon-AVR and click on configure to select the correct speaker configuration?
