Bug 12187

I was able to reproduce the initial issue on hardware available to me.

Interestingly, audio works with headphones, and once the headphones are unplugged, HDMI audio begins working as well, so I think its most likely a configuration issue.

Can you try reproducing the above?

similarly perform different tests with the headphones testing directly on nuc and then via HDMI and it does not work,
probe downloading the image again, relay tests on another nuc of the same model and switch HDMI cables, change monitor and can not get audio in any attempt.

try running this from a terminal:

pacmd set-card-profile 0 output:hdmi-stereo
gst-play-1.0 /path/to/your/wav/file

if the wav file is played but still without audio, I uploaded the whole volume using the arrows above, attached process log.

the audio is only present in the output of the NUC via HDMI there is no audio

I'm thinking this is a kernel issue, as we have found the following:

NUC6, intel-corei7-64: works (with some configuration)
NUC6, genericx86-64: does not work
NUC7, intel-corei7-64: works (with some configuration)
NUC7, genericx86-64: works (with some configuration)

intel-corei7-64 is currently using the linux-intel-4.9 kernel, whereas genericx86-64 is using the linux-yocto-4.12 kernel.

I may try pyro genericx86-64 next.

With pyro genericx86-64 (linux-yocto-4.10), hdmi audio works with no additional configuration.

With master genericx86-64, and PREFERRED_VERSION_linux-yocto = "4.10%", hdmi audio works with the additional configuration above.

There definitely appears to be a new kernel issue with the 4.12 kernel.

his is the type of karnel version,
sh-4.4# uname -r
4.12.12-yocto-standard

 in the automatic test of generixc86-64-nuc and wic, this present this in central error

does not play the audio in wav format, ogg through the HDMI monitor, in 2.4_M4_rc2, there is only the audio of wav and ogg formats in direct of the nuc output

does not play the audio in wav  or ogg format, through the HDMI monitor, in 2.4_M4_rc3, there is only the audio of wav and ogg formats in direct of the nuc output

BUILD: 2.4 M4: rc3-65d23bd7986615fdfb0f1717b615534a2a14ab80 
ENVIRONMENT: Genericx86-64_NUC
 NUC 6i5SYH 
images: https://autobuilder.yocto.io/pub/releases/yocto-2.4.rc3/machines/genericx86-64/core-image-sato-sdk-genericx86-64.hddimg

STEPS TO REPRODUCE: 
1. copy sample wav or ogg file to system
2. connect system with a monitor with HDMI
3. launch media player and play the wav  or oggfile

EXPECTED OUTCOME:
 wav or ogg file can be played without problem, with HDMI

ACTUAL OUTCOME:
the audio is not present with  played wav or ogg file in HDMI

The "snd_hda_codec_hdmi" parselog errors continue appearing in 2.4 RC3 on automatic BSP testing for genericx86-64 images in NUC (in both, wic and hddimg formats). For more reference, I have attached the log file with more details about the execution using the hddimg version.

This is an example of the errors that appear:
