Kodi 18.5 - surround centre channel muffled

Hi forum members!

I am running Kodi 18.5. (Librelec 9.2.0.) I am having some issues with surround sound. On my Sonos Playbar The center channel is muffled only on media with 5.1 surround sound.

Since the problem occured all of a sudden, I am positive that my wires and settings are correct. For the purpose of this question, I will explain it.

Sony TV and Playbar connected with optical cable. Raspberrry Pi 4 connected to TV via HDMI. Sony TV sends the sound to Playbar - audio out is Auto (not PCM)

Important Audio settings in Kodi

Audio output device: HDMI

Number of channels: 2.0

Allow passtrough: on

Dolby Digital (AC) capable reciever on

Enable Dolby Digital (AC3) transcoding - on

Playbar is recieving 5.1 Dolby Digital signal. But, on 5.1. sources, center channel (vocal levels) are low.

Is anyone experiencing the same?

Will reseting my Libreelec configuration to default do the trick or do I need to install Kodi all over again?

Thank you

Have you modified the Downmix- Center Mix level?

I have tried to move the slider. No noticable difference. The voices muffled, but the efects, boom

Thank you for the reply.

Try a real power cycle of all devices (pull the cord for >= 30 seconds).

One by one device or all together?

If the issue persist pull and plug all data cables.

Finally try other HDMP ports and cables.

Is it possible that optical cabe is semi faulty and has problems only with centre channel? I can no imagine that...

Thank you
