LG UM7100PLB + Sonos Beam 2 + 2 x SL + PS5 audio on LPCM is lower than on Dobly/DTS

Hi guys,

These past days I managed to finish building this set up.

My settings: Beam 2 is plugged into the ARC HDMI port, PS5 is plugged in into the standard HDMI port.

ARC output is enabled with passthrough. AV Sync Adjustment is turned on with Bypass on. DTV Audio Settings is set to Auto.

The HDMI input is set to Bitstream.

In the PS5 settings, I set the output to Soundbar.

Even though in the Sonos app I get PCM Multichannel 5.1, the output is really low on LPCM. And by this I mean that most of the sound comes from the Beam (center and the other channels) while the SLs barely have some sound. On DTS/Dolby it's louder and it feels like surround.

I enabled True Playtuning.

Any idea what I got wrong?
