No sound on TV through HDMI

1. Sorry, but I could not find any Information about a "Grundig GU22WDVD01" TV on the Internet.

Did you try another HDMI-Port on the TV or did you use always the same ?

2. You're using the HDMI-Out of your Motherboard ?

If so, did you enable the "HDMI Audio Output" in the BIOS of your Motherboard ?

It must be in the BIOS under "Onboard Device Configuration"

I've got an English Manual of this Board, (Download from here

https://www.asus.com/de/SupportOnly…elpDesk_Manual/ - "H81I-PLUS User's Manual (English)")

Look at Page 2-24 (Picture of the BIOS-Mainpage) and Page 2-31(right on the Top the Setting is described)

3. Look at

System -> System -> Audio (where you can select the Audio Output Device)

Did you set

"Number of Channels" to: 2

and

"Allow Passthrough" to : Off

4. Also it makes me wonder why "ALSA: HDA Intel HDMI" is shown 4 Times.

You only had 1 HDMI-Output on your Motherboard.

Maybe you should "Reset above settings to default"

in System -> System -> Audio (it's down on the Bottom)

then turn off your PC and TV.

Than first turn on your TV and than your PC and look what Kind of Audio Output Devices are now available

Question to the MODS:

This is my 26 Post on this Board, why must it still be checked by a Moderator ?

I thought after 10 Posts this is not necessary anymore ?

Or did I get this wrong and it's 25 or more Post now ?

Niceguy You didn't reached the necessary amount of posts, so you're still a moderated guy. Just continue to be nice.

It's better not to make this public. We don't want to give spammers any target numbers.

Omina did check the Volumen Control on the TV too ?

Display: Grundig GU22WDVD01

Didn't find a "Grundig GU22WDVD01" but after a lot of searching on the Internet a "Grundig GU22WDVD10"

22 INCH GRUNDIG LCD TV HD READY FREEVIEW DVD COMBO MODEL GU22WDVD10 [u'SANDWELL'], Dudley

It's some strange combination between a TV and a DVD player like the "DVD" part in the Modelnumber shows.

It seems that this TV is not widespread (the Information above is the only one I could find) and that it is only HD-Ready and has only 1 HDMI-Port.

So again it makes me wonder why "ALSA: HDA Intel HDMI" is shown 4 Times.

You only have 1 HDMI-Output on your Motherboard and 1 HDMI-Input on your TV.

I've checked my own combination of an Asus Motherboard, LibreElec 9.2.8 and a Samsung TV.

The PC is connected with a HDMI-Cable to the TV and LibreElec only shows 1 HDMI Auido-Output.

And another question to Omina:

If you own this "Grundig GU22WDVD10", do you set the the "Resolution" in Settings -> System -> Display to 1920x1080 or to 1280x720 (which would be betterbecause the TV is only HD-ready) ?

So now we got Picture and Sound until you change the Video-Resolution in LibreElec ?

What Resolution(s) is your TV capable of ?

I think it's 1366x786 because the TV is "HD-Ready" only

Don't change it to a higher Resolution like 1920x1080 because the TV can't show it, and maybe for this reason you got an "Out of Range" message.

What Resoulution did LibreElec show to you ?

If it is 1280x720 it should be OK, and you won't get any problems, because this is a regular TV Resolution.

So if everything is alright I wouldn't change the Resolution.

But for example if some Parts of the Picture are missing or the Picture is stretched we must search for another solution.

If you want you can try this

In Settings -> System -> Display

1. Set "Resolution" to ether "Automatic" your native TV Resolution or 1280x720

This will only affect resolution of the User Interface and has no effect on playback.

If it is available I would set it to "Automatic"

2. Set "Use Fullscreen Window" to "ON" (I think this is done already)

3. Make a "Whitelist" and set it to 1280x720 60.00Hz and 1280x720 50.00Hz only

The LiberElec (Kodi) Videosettings are described here:

Settings/System/Display - Official Kodi Wiki

At last simple a Explanation (I hope I did get it right):

If some AV-Components are connect with a HDMI-Cable and are switch on, at first they "communicate" with each other "telling" the other side what they are capable.

Among other things the TV tells the other Side (for example a Blu-ray Player or even an PC) which Resolution he can show.

It's called "HDMI-Handshake", if you want more Information about it, you can Google it.

So if you turn your TV on first and then the PC, the TV will "tell" the PC of which Resolution he is capable and wich sort of Sound he can handle.

Think I've figured it out - it will play sound when I select interlaced resolutions (1920x1080i, 480i etc) but not when I use standard progressive scan ones (1920x1080p).

I was going to get a better TV anyway but thanks for all your help

You've been reduced HDMI data rate by doing so. Chances are your HDMI cable can't handle higher data rates, so it drops the sound. Get an HDMI 2.0 or 2.1 cable before getting a new TV.

One last Question to Mr. Da Flex:

How can you chose a resolution of 1920x1080 (it doesn't matter if "i" or "p") on a Screen that is only "HD-Ready" and has a native resolution of 1366x786 ?

I though there is this "EDID-File"

Extended Display Identification Data - Wikipedia

for Display Devices which describes their capabilities to a video source and was "transferred" during the "HDMI-Handshake".

So if the TV send this EDID-File to the PC, in LibreElec only a max. Resolution of 1366x786 would be possible.

Or did I get something wrong here ?

Is there a Difference between a TV and a Laptopdisplay `?

Like you know, I tried to install LibreElec 10.0.1 on my Asus Eee-PC and I couldn't get a Resolution of 1280x720 or even 1920x1080 out of it because the Display only has a native max. Resolution of 1024x600.

If it's really just an HD-Ready TV, then it's probably no cable issue. I think HDMI negotiation goes wrong here, and I suggest to create a custom EDID with supported resolutions.

Before that, why not set the Resolution of the User Interface to 1280x720, make a "Whitelist" with only the 1280x720 60.00Hz and 1280x720 50.00Hz Settings and set Adjust display refresh rate (System -> Player -> Videos -> Playback) to "On start/stop" ?

I think Kodi is desinged for working best with standard TV Resolutions like NTSC (720x480), PAL (720x576) or HD 1280x720, 1920x1080 and maybe 4096x2160 (because most, when not all Videos now are in one of this resolutions) and not some "strange" Resotutions (for example 800x600, 1024x768 or 1366x768) a HD-Ready TV or a PC Graphic Card has to offer.

I think for that reason too the Subtitles didn't show on my Asus Eee-PC which had an Resolution of 1024x600.
