Hi Everyone,

I have my Headphones connected to the SPDIF Output and watch TV via the HDMI.

When I select the SPDIF Output, some videos like this one:

Will have audio from both the SPDIF and the HDMI. Why? I didn’t even think it was possible to have audio via both at the same time!

Here are my Audio Setting for using the SPDIF Output:

Here is the debug file when playing the video above.

TIA

EDIT: This is interesting.

Setting the SPDIF as the output and before playing the video.

Ugoos:~ # amixer get 'Audio hdmi-out mute'
Simple mixer control 'Audio hdmi-out mute',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]

After starting to play the video.

​​​​​​​Ugoos:~ # amixer get 'Audio hdmi-out mute'
Simple mixer control 'Audio hdmi-out mute',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [off]
Ugoos:~ #

​​​​​​​Seems playing the video is turning OFF the muting of the HDMI output.

Hi all,

This might help as this Sony Test File will turn OFF the muting of the HDMI Port.

If there’s more info you require, let me know.

TIA

EDIT: Further investigation shows that playing HDR10 or HDR10+ videos are the ones that are turning OFF the muting of the HDMI output.

I would appreciate it if one of the CE Team would take a look at this for me. Thank you.

Hi all,

Been nearly a week now and not one response.

Have I offended the CE Team? Is there missing information you require? Are you just not interested in these types of issues? Is it a low priority problem?

Would be nice to know as this issue is really annoying.

Thank you,

Greg

Hi,

Can one of the CE Team please look into this issue for me?

Thanks.

I’ll bring this to the team but things are a bit difficult form the last weeks. Can’t promise any timing.

@Vasco - That would be great, thank you. This issue has been really annoying for me.

According to the log, seems you are using Plex.

2024-11-05 09:57:05.568 T:4078    debug <general>: PLEX.kodimonitor: ... 'volume': 100, 'muted': False, ...}

So maybe Plex takes control of Audio, and unmutes HDMI?
To crosscheck, try same video playback from local storage.

Same happens if you play video via File Manager and Local Storage.

@Vasco - Don’t suppose anyone has looked into this yet?

10

What’s to look at? Your system is working the way you have set it up.

Disable the Audio Profile addon or configure it differently. Or check how you have scanned the video into your library to see why there is no audio stream details available for it.

First one was rho-bot but no luck. We’ll try yo reproduce and see if it’s fixable. Sorry for the delay

12

@Vasco - Sorry to keep bothering you on this, just wondering if you could reproduce the issue?

13

Tested your file and then another 3 or 4 and I had sound in both HDMI and spdif at the same time even when only spdif was chosen. I’ll report back with why this is happening and if there’s anything we can do.

Great, thank you.

@Vasco - Can I assume no word equals no fix?

Thanks,
