Are you connected to the denon amp through HDMI?
The source (Pi) will read the EDID from the sink (display or AVR) and that will include audio capabilities.
A faulty HDMI cable may make it impossible to read the edid.
ssh in and run:
edid-decode /sys/devices/platform/gpu/drm/card?/card?-HDMI-A-1/edidand you should find an "Audio Data Block" describing the capabilities.
Is this for sure working? I have my tv wake up now but not my avr... Tried every setting with CEC. Cmdline.txt is also not editable from the OS? Thanks
/flash is mounted read-only by default, but you can change that.
mount -o remount,rw /flashThe article you linked to says:
PCM: This stands for “pulse-code modulation.” Use this setting if the external device you have connected to the HDMI port has already processed the sound, and you just want it to come out of your TV’s speakers.
This setting configuration for the Samsung TV changes the signal to 2.0 PCM as it passes through the TV. If you select PCM even though you have a home theater system or soundbar connected, the sound system will only receive 2.0 channel sound and the result will not be multi-channel surround sound, even if the sound system is capable of multi-channel PCM audio.
So that setting is 2 channel PCM only.
Also you are using SPDIF, which can handle stereo PCM, or compressed 5.1 using AC3 or DTS. It won't support multichannel PCM.
In kodi, set channels to 2.0. Enable AC3 passthrough. Enable AC3 transcode. You will get multichannel output from your 5.1 speakers (it will be using AC3 as the actual format that goes over SPDIF).
You can disable it in kodi: https://kodi.wiki/view/Settings/System/Input
There is almost certainly a similar setting on TV. It may be referred to by one of these names.
You are getting repeated select button presses over CEC (i.e. from TV or other HDMI connected device).
Try disabling CEC in settings.
this might be it: llctl
If I revert the backport of this PR (https://github.com/xbmc/xbmc/pull/21410), the closed caption subs work again.
Interestingly with it working, kodi sees one subtitle stream.
With it not working kodi sees two subtitle streams (but neither show anything).
I've pinged the dev, so may be no need for the issue if they can reproduce issue.
I can play that stream (in UK). And it doesn't have close captions on LibreELEC on Pi.
It does have closed captions on VLC.
I installed kodi on Ubuntu 22.10. It describes itself as:
Kodi from Debian (20.0-ALPHA2 Debian package version: 2:20.0~alpha2+dfsg1-1build1). Platform: Linux x86 64-bit
and it behaves the same as kodi on pi. No subs or closed captions visible (although I can choose between two options).
As this seems to be a general kodi issue, it's best to report it here.
Make sure you follow the template, include a debug log, indictate which versions of kodi this worked on, and which it fails on
Include the URL to reproduce the issue, and hopefully someone who knows this code can help.
Can you test with "Allow hardware acceleration with DRM PRIME" disabled?
If that works, test with "Allow using DRM PRIME decoder".
I know the streams may not play well with these options disabled, but it may narrow down where the problem lies if you confirm if closed captions start working.
It would be helpful if you can find a file that has the issue that isn't geolocked.
Yes, disabling DRM Prime isn't recommended but provides a workaround if you just need to screenshot video occasionally.
Perhaps not an important feature for most users but the screenshot command still does not work in LE 10/11 (it does not save the screenshot picture like in release 9.x but only the active GUI screen).
Assuming this is an occasional requirement, if you disable DRM Prime in video acceleration settings first, I believe screenshot will work.
Use 10.0.3 and add "vc4.force_hotplug=1" to cmdline.txt (on end of existing line).
The things you mentioned are all normal and occur on my system with working audio.
Another display would be a useful test.
Also if your current display has another hdmi port try that.
I don't see any audio errors in log (it looks much like mine).
Can you confirm if any local setting are causing the issue? Simplest way is to ssh in and:
systemctl stop kodi
mv /storage/.kodi /storage/.kodi_back
systemctl start kodiYou should now have kodi running with default settings. Any audio from navigating gui or playing a video?
If you want to return to your old settings then:
systemctl stop kodi
rm -rf /storage/.kodi
mv /storage/.kodi_back /storage/.kodi
systemctl start kodiI have noticed that the latest nightly does have the same kernel oops as in the original log. So favourite is the popcornmix fix scheduled for linux 6.1, maybe it has not been back ported to 6.0.5 properly.
You are correct. I've just checked and the fix from 6.1 is missing from 6.0 tree. I've cherry-picked it to rpi-6.0.y, so should appear next time LibreELEC bumps their kernel version (probably best to wait for confirmation here, as that's not an automatic process).
I believe a backport of the VC-1 patches are in current LE. e.g. see https://github.com/LibreELEC/LibreELEC.tv/pull/6538
I think errors like "mmco: unref short failure" are common when source is live TV (where there may be errors in stream, or it may start from a non-I frame). I don't think it fatal for playback.
But otherwise I don't know much about non-pi kodi, especially the audio drivers (which sounds like where the issue is).
Kodi is left running all the time and the LG is put into standby with the remote. After a while, the TV is restarted and the message no video signal appears.
Looks like you are using the Nightly/kodi 20 build. I assume that stable/matrix build works okay?
The error relates to i2c, and may be fixed by this.
