I need to try the LE 12 nightly and see if it resolves the issue.

If not, share a log from the nightly...

Quote from REXus

In both cases used format is AE_FMT_S16NE, present on both platforms. What about frames, which is diffrent? Is there a way to change them?

If connection breaks on a higher frame rate (only audio in your case), then it's sometimes bad HDMI cabling.

I would check whether your HDMI cable(s) is/are conform to HDMI 2.0 or 2.1. Those cables have better shielding, so they can handle higher data rates (4K video, HD audio etc.).

Thanks. LE and OSMC receive different capabilities from the AVR.

Differences are at "dataFormats" section. Missing data formats on LE:

• AE_FMT_S24NE3
• AE_FMT_S32NE
• AE_FMT_S16BE
• AE_FMT_U8

I guess you found an LE bug. Wait for chewitt now.

Understand, the reason i asked for help is some of the add-ons impacted would appear to be popular for example uTube and OpenVPN ( to use with NordVPN)

Use our search function (magnifier icon) with "YouTube" or "VPN" as keywords.

Pro tip: Start your search from the forums main page to search in all sub-forums.

I've tested a Behringer UMC22 on my RPi, and it works fine. The output is studio quality, if connected to active studio monitors.

Python version is compiled into LE. So you can't change the Python version on LE. You can only downgrade LE.

If you're disappointed with the situation, ask the add-on developer to compile with a newer Python.

Quote from REXus

Why "channel count" is 2?

Try two output channels on LE's audio settings. As mentioned, the six DTS channels (see log) will be encoded into those two.

Quote from REXus

Sound system configuration is fine, because it worked well with Raspberry Pi + OSMC (well, there were another things that not worked).

Do you have another microSD for LE on RPi? Then we could compare both logs.

Multiple audio channels can be encoded into two channels, so don't care about it.

Looks like LE doesn't support audio passthrough on your device:

Quote from REXus

Worked fine on OSMC installed in Raspberry Pi with same files. So AVR should not be a problem (it supports up to 96 kHz and 24-bit).

Thanks for the info! Your AVR is a good one.

I guess we have to dig deeper now...

You have to struggle when trying to compile your own EQ add-on. Nobody will do it for you.

Don't waste your time, and buy a hardware DSP.

Quote from REXus

Hi! I'm new here, and I've just installed LibreELEC on my old Odroid C2.

Everything works fine except for sound passthrough. While this feautre is disabled, sound works, but only in stereo. If I enable it, at the beginning of every video I hear "crack", and then, if sound is in format accepted by my sound system (selected in Kodi options) there is silence and sound system indicates no digital data, else - if sound has to be converted to other format - sound comes in stereo.

Sound system configuration is fine, because it worked well with Raspberry Pi + OSMC (well, there were another things that not worked).

Any ideas?

I recently had a similar issue with passthrough on RPi3B+. So if your AVR is old, then the issue could be a high sampling rate.

Quote from jazzlpunk

Thanks, then I will also need to provide a log file again, right?

If it doesn't work with LE 11.0.3 either, yes.

10 / 12 bit deinterlacing is a know issue. As a workaround, disable deinterlacing at playback menu (gear icon).

OK, I've tested testfile2.TS on my RPi3B+. I can replicate the issue with my AVR.

The test file has AC3 audio. If your AVR can't play all AC3 streams, you have to edit LE's passthrough setting:

1. go to Settings -> System
2. on the bottom-left, set GUI mode to Advanced or Expert
   
3. go to Audio
4. enable Allow passthrough
5. disable Dolby Digital (AC3) capable receiver

My AVR has Dolby Digital and DTS, but I guess it can't handle higher sampling rates on Dolby Digital.

11.0.3 is latest. If you can't find it in the menu:

1. login by SSH
2. cd /storage/.update
3. wget https://releases.libreelec.tv/LibreELEC-RPi4.arm-11.0.3.img.gz (for RPi4)
4. reboot

Please update to latest LE. I don't think it will fix the issue, but you'll get more attention from devs.
