Setup: LG OLED65C2PUA (2022 model with eArc) with Sonos Beam 2; One SLs surrounds; and Sub Mini with Tivo (Android TV) Mini via 600 Mbps fiber optic.
Problem: While watching broadcast TV channels the audio on S2 now showing Stereo PCM or Dolby Digital Plus 2.0, and sometimes Dolby Multichannel PCM 2.0, but I used to get Dolby Digital Plus 5.1 before software update of the Tivo Mini
I get Dolby Atmos and DD+ 5.1 while using Amazon Fire TV Stick 4K Max for streaming services
