Everything is working... thank you very much guys!

In order to make the NUC6CAYH function correctly you have just to upgrade the BIOS and the Firmware of the NUC link text. You will need a Windows installed in the NUC in order to install the updates.

I guess the same problema happens in NUC7ixBN, cause the firmware upgrade is availiable for both models.

The model is NUC6CAYH

Note 3 : Keep your resolution no higher than 1920x1080 or no sound via HDMI again..

I have tested playing a youtube video in Ubuntu Live USB and the audio start functioning when the resolution is lower than 1080p

:S

@maldorhan I have news on this topic... I have connected the NUC to other TV with Ubuntu and I have sound! When I connect again the NUC to the Samsung Smart TV, the audio is off again...

Searching on the Internet I found that the NUC does not send audio output throught HDMI with 1080p resolution... The TV that I used to test has a smaller screen and that why the sound works.

So, is it possible to change the screen resolution in recalbox for emulastation and emulators?

@maldorhan No, I can not listen the emulestation song, neither the sound in games (I have just tested with Crazy Taxi for DC).

These are my audio settings in recalbox.conf

------------ C - Audio ------------

Set the audio device (auto, hdmi, jack)

audio.device=[0:3] HDA-Intel - HDA Intel PCH + HDMI 0

Set system volume (0..100)

audio.volume=100

Enable or disable system sounds in ES (0,1)

audio.bgmusic=1

@substring everything is max/unmuted but the audio is not working :_(

@maldorhan thanks for your answer.

The NUC is conected to a Samsung Smart TV.

Hello everybody,

I hope someone could help me on this forum... as you can read in the topic title, I have bought an Intel NUC6CAYH for Christmas cause I want to run Recalbox x86_64. Until that I was using a RPI3 with good results, but I decided to try with a NUC to emulate more powerful systems such us GameCube or Dremcast.

The problem is the audio... I can not listen anything when I use recalbox or kodi. I have tested every parametter I found on the Internet (to force hdmi output, to force alsa, etc, etc.) but I'm always getting the same result: No Audio.

This is the output of aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog]

Testing again and again, under some circunstances, recalbox detects only 3 audio devices (the first three devices of aplay output) and then, audio is working properly. But when I restart, the audio is lost. If I check again the aplay output I can find the 5 devices.

This scenario happens randomly when I retart about 10 times the NUC...

Any ideas guys?

Thanks in advance.
