Raspberry pi 5 only 2.0 for ppm. Passthrough works fine on all channels

I'm using the latest LibreELEC Omega 12 build on a raspberry pi 5, with the jellyfin plugin.

Whenever I play a video with passthrough audio that my tv/soundbar (sonos arc with surrounds) supports, it works fine on all channels.

If I play a video file that doesn't use passthrough (e.g. aac), all the audio only comes from my front speakers.

If I run speaker-test -c 6, all audio also comes out of the correct speakers, but some channels are marked as unknown:

Any ideas how I can make non passthrough audio come through all the correct channels?

Many thanks

Hi

Here's my debug log file while I tried to play an hevc file with 6 channel aac audio:

https://paste.libreelec.tv/subtle-toucan.log

This is using the latest nightly build, LibreELEC (community): nightly-20240513-bcd4d7f (RPi5.aarch64)

Many thanks!

And here's a debug log while playing an hevc file with 6 channel ac3 audio using passthrough, where all the audio comes out of the correct speakers:

Hi

I've tried all the permutations of sound settings on my TV with no luck.

getedid-create failed when only my soundbar was plugged in, error saying it couldn't get connections.

As the RPi5 has 2 hdmi outputs, I plugged one into my tv and the other directly into my soundbar, then ran getedid create and got the following two edid outputs:

After a reboot, the problem was the same, only Front Left and Front Right speakers showing, but speaker-test -c 6 sounding correct but showing:

Any other ideas? Or is there any other way to force it to recognise the surround /lfe channels - asound.conf etc?

Many thanks
